I Finally Found Out What 0/0 Should Be

www.udemy.com/course/prove-it...
0 divided by 0 is sort of a mystery. Does 0/0=1? Does 0/0=2? Is 0 over 0 infinity?
If we are talking about a 0 over 0 limit, we say 0 over 0 is indeterminate. However, in this video we won't focus on any 0/0 limit rule. Instead, we will try to figure out what 0 over 0 equals. Hopefully, we can have 0/0 explained.

    This is the type of guy that doesn't take (0/0, or no) as an answer! Also, if we take (0+0)/0 instead (0-0)/0 = 0/0 = x-x= 0 but 0/0 is also x. So 0/0=x=0. So we reach a contradiction: the *only* solution for 0/0 is 0, but also based on the sol presented in the vid, 0 *AND* infinity.

And it doesnt make sense within this universe, but the way people solve things that end up with division by zero is using limits. Sometimes the limit exists, sometimes it doesnt, but I feel like 0/0 could be defined as any number in existence

    I still think undefined is the best way to go about this and my main reason is through physics. Mass is equal to force divided by acceleration. However, if an object has no resultant force applied to it and is not accelerating, then it's mass could be calculated by 0/0. We know this mass could be anything, meaning the mass is undefined by this equation. This doesn't make the object have infinite mass or every object that wasn't accelerating would become a black hole of infinite density and destroy anything around it, which isn't the case. This isn't a solution derived from actual mathematical approaches so there are probably a lot of counter examples to this point but I felt this could be an interesting talking point.

This format (like every other fixed-precision floating-point formats) has precision limits which render some calculations into no-ops (they do nothing, even though data has actually been processed). Each format has its own specific limit, both for large absolute values and tiny abs values. "binary64" reaches its limit when the abs value reaches 2^53, because the mantissa has 52 real bits and 1 "ghost" (implicit) bit.

Floating-point is the opposite of Fixed-point, it means the "decimal" (actually binary) point can be moved freely left or right, you can represent a wide range of magnitudes (like the size of a solar system measured in centimeters, or the size of an atom measured in meters, although not with 100% accuracy). Fixed-precision means the memory use is constant, never grows, never shrinks, so there's a limit to both the magnitude (exponent) and mantissa (significant digits). It's just scientific notation but with specific (non-arbitrary) constant limits. The "ghost bit" is a bit whose value is always "1", so it doesn't need to be written in memory, therefore making it implicit, and squeezing more precision out of the limited memory. Trailing zeros are the zeros to the right, big numbers require them to preserve the magnitude if the mantissa is filled to the brim, these zeroes are also "ghosts" but in a different way, since their existence is purely mathematical (not in memory). The exponent is also responsible for "adding" these trailing zeros

    infinity is quite a few different numbers, actually. 0/0 is not encompassed by infinity, because infinity is valid mathematics, 0/0 is not. Bri got it wrong by assuming that 0/0 obeys mathematical principles, and thus concluded that it should be infinity according to that. but 0/0 lies outside of the scope of mathematics, so that assumption is wrong, and thus the conclusion that 0/0 has a relation to infinity is also wrong. it's trivial in fact to get division of any number at all by zero to appear to be any number. for instance, you can drop a hole into y=x at absolutely any point by simply multiplying both sides by 1, as shown below: - for any n != 0, n/n = 1 - y*1 = y, x*1 = 1, thus y = x is identical to y = x*1 - given both of the above y = x * n/n - to get division by zero at x-value m set n = x - m - now at x = m, y = x * (x-m)/(x-m) is identical to y = x * 0/0 - since x * 0 = 0, this means that we have y = 0/0 - if we take the limit here we will get that y = x, and thus at x = m it is necessarily true that 0/0 = x - since we can set m to absolutely any value we want 0/0 is thus also equal to absolutely anything and everything simultaneously if we look at other functions, like tangent, we can see that division by zero also shows up where solutions are impossible, like for tan(pi/2), where the limit from the left is positive infinity and the limit from the right is negative infinity. it's not possible to have two values more different from each other, yet division by zero yields both simultaneously an infinite number of times with just this one function.

    @@sumdumbmick *infinity is quite a few different numbers, actually.* No, it is not. This is a nonsensical statement. Infinity is a property of sets. Definitionally, we say that a set S is infinite if and only there exists an injection from the set N of natural numbers to the set S. Every number system is a set, as is every object in mathematics, and some number systems have infinite elements, and those elements are numbers that are infinite. There is no number called "infinity", though, because "infinity" is a property of sets, not a number. *0/0 is not encompassed by infinity, because infinity is valid mathematics, 0/0 is not.* This much is true, though I get the impression we will strongly disagree as to _why_ this is true. *it's trivial in fact to get division of any number at all by zero to be any number.* This is a bold claim, and I take this to be the thesis of your comment, so I will be deconstructing the rest of your comment in context of this thesis. *now at x = m, y = x·(x - m)/(x - m) is identical to y = x·0/0. Since x·0 = 0, this means that we have y = 0/0.* Not so fast there. In order to conclude that x·0/0 = 0/0, you must necessarily assume associativity of ·, which is not at all warranted here. *if we take the limit here we will get that y = x,...* No, this is a nonsensical claim. In the equation y = 0/0, there is nothing to take the limit with respect to, we just have two constants. Also, limits are irrelevant to questions of evaluating arithmetic expressions. *if we look at other functions, like tangent, we can see that division by zero also shows up where solutions are impossible, like for tan(π/2), where the limit from the left is +♾ and the limit from the right is -♾.* Yes, it is true that lim sin(x)/cos(x) (x π/2) = +♾, and lim sin(x)/cos(x) (x > π/2, x -> π/2) = -♾. However, this has nothing to do with the topic of division by 0, since the denominator is never equal to 0 in these expressions. What you have proven is that lim tan(x) (x -> π/2) does not exist, which does not itself prove tan(π/2) is undefined. In fact, I have an easy counter-example to your claim. Let f : R -> R with f(x) = 0 if x = π/2 + n·π, where n is an integer, f(x) = tan(x) otherwise. Then here we have lim f(x) (x -> π/2) does not exist, yet f(π/2) = 0. This disproves your claim that lim f(x) (x -> π/2) not existing proves f(π/2) is undefined.

    There's no glitch in the expression:[0/0]. The issue is that the term "what is" has no meaning in mathematics, especially in algebra... unless you're describing which categorical numerical set certain numbers exist within. For example, that 1 is a real number, or that π is irrational. That's completely different from asking what x "is" in the equation y=x/0. "Is" is a linguistic artifact, spoken by amateur mathematicians who aren't interest in solving equations the correct way to begin with. That's where the aberration is introduced; it's a cultural mistake, not a systematic variety. Here is the answer:[ [0/0] ⇒ [0=0] ] In English, that says that zero over zero is zero equals zero. Next, let's make it x/0 to see what happens. [ [x/0] ⇒ [x=0] ] Put this on a graph to see what happens. www.google.com/search?q=0 That's just a graph of zero. However, the Zero Property of Multiplication states that 0=0*y for any real number y. The Multiplicative Property of Equality states that we can divide both sides by any real number to derive an equivalent statement. So that's actually a graph of y=0/0. And y=x/0 is also that graph, because:[ [x/0] ⇒ [x=0] ] There's no mathematical errors here. x/0=y doesn't define y. So we say that x/0 _"is"_ undefined. That doesn't mean that we broke math, or this is an undiscovered operation. We know what it means. It means that y can be any real number. That has a meaning in mathematics. We call it 'undefined,' not because we don't know what it is, but because we do know what it is, and what it is is any real number. Defined means that out of many, we've selected some of them, which is what x is in this case. x is the number that's defined in the equation y=x/0. What is x's definition in this linear graph? It's 0. I'll prove it. [ [y=x/0] ⇒ [y*0=x] ] [ [y*0=0] ⇒ [0=x] ] There it is forwards, and backwards. Sorry, but this is already a solved case. If you learned the basic properties of algebra you would know this already.

Nothing ever equals infinity, things can only approach infinity as you change a variable. For example, x/y approaches infinity for x>0 as y tends to zero from the right. Whenever you hear a mathematician say something equals infinity it's shorthand for a limit of some kind. B) let's use expression x/0 x/0 isnt infinity as the rules of algebra say that, if x/0 = infinity, then infinity times zero equals x, for any x you choose. IF x/0 = ∞, THEN ∞ * 0 = x However, this is obviously wrong as any number multiplied by zero is zero. And infinity is not a number, it's an idea. C) assuming the expression x/0 and x is 10 apples, you can't add an infinite amount of zero groups together and end up with say 10 apples also you can rationalise 0/0 much simpler using the idea that division is the inverse of multiplication: 0/0 = 0 is absurd and incorrect because it would allow for the proving of 1=2 (which obviously is absurd) 0x1 = 0 0x2 = 0 lets say we allow the division of 0: 0x1/0 = 0x2/0 (both divided by 0, so equivalent to previous lines) (0x1/0) x 1 = (0x2/0) x 2 (both times by 1, so equivalent to previous lines) cancel out the zero on both sides and you get: (0/0) x 1 = (0/0) x 2 cancel out the expression 0/0 on both sides and you are left with 1 = 2, which is obviously incorrect meaning division by 0 is impossible

Historically, when calculus was rediscovered by Newton and Leibniz (I say rediscovered, because it is now well-known at this point that techniques of calculus has been used millennia before), they formulated it by appealing to infinitesimal quantities, and they called it infinitesimal calculus. The concepts of the derivative, the integral, and the method of exhaustion, were then understood as special applications of this infinitesimal calculus. The primary notion in this infinitesimal calculus was that there existed infinitesimal nonzero quantities ε that were taken to have the property that ε^2 = 0. This method, though, was extremely nonrigorous and very heavily criticized, it being widely seen as apparently inconsistent and leaving too much ambiguity. This created problems for calculus as a mathematical application. Later, when real analysis was invented, calculus was reformulated in terms of topological ideas and ε-δ arguments from real analysis. What this allowed was for a consistently rigorous mathematical theory that allowed us to do everything that calculus was invented to do, all without ever needing to appeal to infinitesimal quantities at all, instead, relying solely on the properties of the real numbers. Limits were invented not to allow calculations that involved division by 0. They were invented to set calculus on a foundation that did not rely on ill-defined infinitesimal quantities, but instead only on the properties of the already known system of the real numbers.

    @@victorscarpes *Do infinitesimals create a bunch of weirdness and inconsistencies? Absolutely.* They _used_ to. This is why they were replaced by limits. However, infinitesimals did not stay defeated, and they have made a comeback. In the mid 20th century, a mathematician by the name of Abraham Robinson develop a rigorous system for dealing with infinitesimal quantities and infinite quantities, a system that was dubbed "hyperreal numbers". These numbers are the basis for nonstandard analysis, which can serve as an alternative foundation for reformulating calculus in a simpler way. In this reformulation, limits are replaced by the standard part function. The standard part function is a function that gves you the real number closest to the finite hyperreal number you input. So for example, if I have a hyperreal number 7 + ε^2, where ε is infinitesimal, then st(7 + ε^2) = 7. If I have -3 - ε, then st(-3 - ε) = -3. When defining the derivative, you can simply define it as st([f:(x + ε) - f(x)]/ε), where f: denotes the natural extension of f to the hyperreal numbers. However, since this system is recent, relative to the history of mathematics, not many textbooks have been written implementing this system for educational purposes and it is not yet part of curricula in most countries. It is likely it will become common in the future, though.

    You can consider multiplication as a way of ssimplifying successive aditions, 3x2= 2+2+2 (or 3+3). So, when it comes to division you can consider it as a way of simplifying successive subtractions (only with natural numbers), 10÷3=10-3-3-3=1 (means you can subtract the number 3 three times and the rest will be 1- natural numbers of course). So, having that in consideration, x÷0= x-0-0-0-0-0.....=x, which means you can subtract the number 0 infinite times and the rest will be the x. The same way 10/3=3 and rest 1, x/0= infinity and rest x.

    @@findystonerush9339 0/0 being equal to infinity or 1 is semantically and mathematically impossible as A) infinity isn't a number per se: infinity is not a value. Its a name given to a "boundless limit". Nothing ever equals infinity, things can only approach infinity as you change a variable. For example, x/y approaches infinity for x>0 as y tends to zero from the right. Whenever you hear a mathematician say something equals infinity it's shorthand for a limit of some kind. B) let's use expression x/0 x/0 isnt infinity as the rules of algebra say that, if x/0 = infinity, then infinity times zero equals x, for any x you choose. IF x/0 = ∞, THEN ∞ * 0 = x However, this is obviously wrong as any number multiplied by zero is zero. And infinity is not a number, it's an idea. C) assuming the expression x/0 and x is 10 apples, you can't add an infinite amount of zero groups together and end up with say 10 apples also you can rationalise 0/0 much simpler using the idea that division is the inverse of multiplication: 0/0 = 0 is absurd and incorrect because it would allow for the proving of 1=2 (which obviously is absurd) 0x1 = 0 0x2 = 0 lets say we allow the division of 0: 0x1/0 = 0x2/0 (both divided by 0, so equivalent to previous lines) (0x1/0) x 1 = (0x2/0) x 2 (both times by 1, so equivalent to previous lines) cancel out the zero on both sides and you get: (0/0) x 1 = (0/0) x 2 cancel out the expression 0/0 on both sides and you are left with 1 = 2, which is obviously incorrect meaning division by 0 is impossible D) if it were equal to infinity, it would be equal to negative infinity, as infinity is a direction. So to find out the difference, we'd simply do infinity - negative infinity, right? By doing this, we run into the Hibbert's paradox of the grand hotel. Suppose Hilbert’s hotel has an infinite number of rooms and infinite number of guests are booked into the hotel. By common sense, it seems like the hotel is fully booked right? Wrong. Infinite sets just defy logic. Suppose there was another guest who wanted to book into the hotel, all the hotel staff have to do is just shift guest in room number 1 to the next, the guest in room number two to the third and so on… So by this logic ∞+1=∞ Similarly ∞−1=∞ Just remove the guest from room number 1 and shift the remaining guests to the predecessor of their room numbers. You still have an infinite number of guests. Let’s apply this logic then Seemingly ∞−∞=0 But suppose we remove the guests which are present in the rooms having an odd number(1,3,5…..) we still have infinite number of guests. So we get ∞−∞=∞ Let’s remove all the guests except the ones present in the first 50 rooms. So ∞−∞=50 You see where I’m going with this? Simply that ∞−∞ is indeterminable. So as a result, x/0 is indeterminable as assuming it leads to infinity, the natural convention is that it leads to negative infinity, and attempting to calculate the origin by subtracting them from each other leads to a paradox

    which works quiet well with the infinit different limits you can get with 0/0. Like yx/x will always be y so we get any limit for 0/0. If we add 1/x to it we also get ±∞ and thus the extended real numbers. It will work with complex numbers aswell. Possibly for quarternions as well. So our current rules for any field will lead to limits of 0/0 sitations to be anything. Which is also a good reason to leave 0/0 undefined.

    This is what Bri was referring to about his last video if anyone is wondering: One workaround to this is to define any such indeterminate forms to equal the nullity, ⊥ . It’s essentially an absorbing element that is more “powerful” than 0 or ∞, so we define results like: 0/0 = ⊥ 10/0 = ⊥ etc… Same goes with indeterminate forms involving infinity. ‘⊥’ has the properties: x + ⊥ = ⊥ ⊥ + ⊥ = ⊥ x ⊥ = ⊥ x / ⊥ = ⊥ ⊥ - ⊥ = ⊥ etc… for any x, including x = ⊥ The only exception to our standard maths rules are the properties 0*x = 0 and x / x = 1 for any non-zero number x, and also x - x = 0; Since ⊥/⊥ = ⊥ and 0*⊥ = ⊥ etc… So basically rather than just infinity, we create a new concept ‘⊥’ which we can treat like a number. Again this is only a theoretical work-around to the problem, it is not official.

    You must look equation as finding a solution set. If zero is possible, you should take care of this case accordingly during the process of calculations. If zero is not possible, you should prove that It must be the case. For example, If (x^2-1)/(x+1)=-2, then x must be different of -1, because It would say that we are deviding by zero which is not possible, hence, for x not equal to -1, we have ((x+1)(x-1))/(x+1)=-2 hence x-1=-2, hence x=-1. Which is a contradition with the hypothesis. This means that there is no solution for this problem. Usually, contradiction comes from this type of equation. The basic tip is to redo the calculations with care when some contradiction comes to appear. Logically thinking, this is because we have left behing some piece of information during the calculation that would show the problem in the computations. Can you imagine what would happen if I hadn't realized that x=-1 is not a solution? A simple substituition of x=-1 would solve that problem and let we know that x=-1 can't be a solution, but in exams It is not easy to predict what would happen.

What you have however are 2 pizza halves, hence 1 divided by 2 equals a half. So, using pizza slicing as a definition for division (which is perfectly fine), we arrive at : given A pizzas, and B pieces, we call the size of the pieces A/B Exemple : 15/3 is 15 pizzas "sliced" into 3 pieces of 5 pizzas each. 15/3=5 So, what would be 0/0 ? 0 pizzas sliced into 0 pieces of pizza. What size is my no piece of pizza ? Well, I have 0 piece of 50000 pizzas, so should 0/0=50000 ? No, since any piece size would work here, by practical maths, there just can't be any answer to question. And that's fine, since in practice, there are many questions where we don't have an answer to.

    When I was little I tried to devise a system where 0/0 = 1. I Said 1/0 is some constant called Omega, and 0 times Omega is 1. To resolve the issue where 0 + 0 = 0 implies 2 = 1, I asserted 0 + 0 > 0 instead. I let 0 be defined as 1 - 1. Therefore 2 - 2 > 1 - 1. This also means for example 3 - 2 > 1. Zero squared is 0 - 0. 0^2 - 0^2 = 0^3, etc. I constructed an infinite sum k = 1 + 0 + 0^2 + 0^3 etc, and noticed that 1 - k behaves like the new "zero," breaking division and such. To resolve the new issue of division by 1 - k, I devised a system where (1-k)/(1-k) = 1, and 1/(1-k) = Omega_1, wherein a new constant k_1 such that (1 - k_1) caused new division problems until the creation of the new constant Omega_2, etc.

    I've always thought about multiplication and division as an organization of groups; for example X multiplied by Y is the same thing as X groups of Y. Similarly, X divided by Y is the same as turning X into a number of groups equal to Y. Explaining all of that probably seems redundant because most people might have already concluded all of that on their own, but most of the reason I'm doing it is just put things into words rather than symbols for the purposes of creating a more mentally tangible situation. Anyways, apply this to what 0 represents: nothing. If you take nothing and put it into no groups, that means there are no groups of nothing. By definition, having no groups of nothing would mean you have no groups in which nothing resides, as in, every group has something in it. Thus you effectively have everything. I think one reason why all of this might be an issue on a computational level is because you can only describe the answer by what the input is not. Hopefully all of that was understandable and logically sound.

    I think it should be 0 because infinitely expanding nothing should give you nothing. In more detail, in the expression a/b for a != 0, the limit of a/b as b approaches 0 is infinity or negative infinity (depending on which side you start from. That is, dividing by 0 is like infinitely expanding (in one way or another). Basically, when you divide a number by a value between 0 and 1, the smaller the denominator, the larger absolute value the resulting expression gets. So I see dividing by 0 as the ultimate expansion operator. Great, so if you infinitely expand anything other than 0, the result is infinite. But I think things should be different with 0. If you infinitely expand 0, you still get 0. If you have nothing and then infinitely zoom into it, you will still see nothing! But if we accept that 0/0 should be infinite, then we are saying that 0 is indeed something that can be expanded, which to me contradicts the very notion of 0, which is pure nothingness. So, infinitely expanding 0 should still be 0 from a philosophical point of view.

    Except it often isn't. The whole idea of Calculus is actually based on taking the difference quotient formula (essentially a modified slope formula for curves) and applying what happens when you make the change in x and make it zero. This in turn makes the change in y also zero. With the exception of whole numbers (like an equation of y=7), the result is not zero, but instead a whole other function that describes the slope of the line tangent to the original equation.

If you got a bucket of nothing and keep trying to fill it with nothing then you can constantly keep filling it and infinite amount of times thus inversely. You take as much nothing out as you wish. It is why personally I avoid the question by denouncing zero as a number in the first place and more of a concept

    0/0 = 0 is absurd and incorrect because it would allow for the proving of 1=2 (which obviously is absurd) 0x1 = 0 0x2 = 0 lets say we allow the division of 0: 0x1/0 = 0x2/0 (both divided by 0, so equivalent to previous lines) (0x1/0) x 1 = (0x2/0) x 2 (both times by 1, so equivalent to previous lines) cancel out the zero on both sides and you get: (0/0) x 1 = (0/0) x 2 cancel out the expression 0/0 on both sides and you are left with 1 = 2, which is obviously incorrect meaning division by 0 is impossible as for the first part, say we have 20 oranges and want to distribute them amongst a table. if i wanted to divide them into 2 groups, the expression would be 20/2 meaning each person receives 10 oranges. if i wanted to divide it into 1 group, it'd be 20/1 --> each person receives 20 oranges for dividing by zero, however, what is the number of oranges that each person receives when 20 cookies are evenly distributed among 0 people at a table? There is no way to distribute 20 oranges to nobody, so the resulting answer is undefined, not zero, because the parameters defining how the oranges are to be distributed are zero

    My job is disease modelling, and it's common to model infection rates as beta*S*I/N, where beta=infection rate coefficient, S=no. of susceptibles and I/N=the proportion of the population that is infectious. However there are situations where you get a pathological S=0 and I=0 (e.g. everything has died in that area), but you want your model to keep going because there's stuff happening elsewhere. In those cases I say 0/0 = 0, since the infection rate when there are 0 individuals is 0. I suppose technically it's 0*0/0, which is more strongly 0 than just 0/0, but even in other situations where 0/0 appears I typically want to interpret it as 0. So the answer is: given the context, what do you want it to be?

In the expression 0/0=x in which I solve for x, I can rewrite it as: X×0=0×0 using inverse multiplication to solve for x. 0×0=0 X×0 regardless of the value of x will lead to 0. As well, if rewritten as a division (0÷0) how many times does 0 go into 0? 1 time, so 1 0. In the example of 2÷1 1 goes into two 2 times, so two 1's (1+2=2) in 1÷1 how many times does 1 go into 1, one time (1). In 100÷10, how many times does 10 go into 100? 10 (10+10+10+10+10+10+10+10+10+10) So in 0÷0 how many times does 0 go into 0? 1 time (0) 1 time. This breaks down immediately when you go to check though: 1×0=0 but so does any other number multiplied by 0. So the answer is variable by definition, which is why it's better to use an x as the solution in an equation. Thus: 0/0=x 0/0×0=x×0 0=0 (no matter what x equals, for this equation to be equal, this side must be 0.) So inverse multiplication is the best approach for solving this problem

    @@ladymercy5275 From my personal interpretation, I always interpreted undefined as a value that can not be defined using out numerical system. For example, before i was invented as the square root of -1, the square root of -1 for some time could not be defined, thus considered undefined until we chose to define √-1 as i. Another example would be the limit as X ➡️ 0, for 1/x. The limit does not exist, so I would also say it is undefined. Indeterminate, on the other hand, from my personal interpretation, states that a value can not be determined to either exist as a value in our numerical system or not, as defined by the term undefined. In layman terms, undefined means "There is no value that can be attributed to this algebraic expression" while indeterminate means "it is impossible to determine whether this value exists in our finite complex numerical system or not." A good analogy for this is whether a person is atheist or agonist. The atheist is confident that no god exists, this is the undefined form. The agonistic can not determine if God exists or not, this is the indeterminate form.

    0/0 would be 1 if 1/0 could exist. Unfortunately, the existence of 1/0 contradicts the associativity of multiplication, and it also may contradict the distributivity of multiplication over addition, or the associativity of addition, depending on how one chooses to define the algebraic structure. Regardless, if multiplication is not associative, then even if every element has a multiplicative element, one cannot coherently define a division operation.

    I don't think this analogy works since taking pieces from a pool of pieces doesn't represent division since we usually associate division with taking fractions of a whole pice, not multiple indivisable pieces. So it becomes quiet difficult: If we have a whole "non" piece (a piece that is nothing as a place holder for 0) and try to take a "non" piece of it are we left with an infinit amount since we take nothing away. On the other hand we can't take anything from nothing so we get nothing.

    The issue of dividing something with a small number approaching zero is that the result approaches infinity for tiny positive denominators but the result also approaches negative infinity for tiny negative denominators. For exactly zero the result becomes a contradiction between positive and negative infinity. Before adding the additional oddity of using 0 as the numerator, I think it is meaningful first to acknowledge the fundamental issue that you're dealing with in the denominator.

    It has been ages since I was in school and was not a good student. (well since I was 13 anyway) one of the things they always thought is that you don't divide by zero. I once thought about what about 0/0 first answer I got is simply you don't devide by 0. which is not a satisfactory answer because it isn't an imaginary number (at least the way I understand imaginary numbers like I said I'm not a good student) unlike if you divided any other number than zero by zero. because if you use multiplication as reverse of division you do arrive at correct numerator unlike it is in the case if you divide any other number by 0. I do agree that zero over zero is undefined if undefined simply means it has no single answer. but I do believe that it being every number that multiplied by 0 gives you zero a correct answer its just not a singular answer but multiple of answers. as far as 0/0+1= 0/0 being impossible because x+1 is not x in this case if x=1 then 1+1=2 and 2 is not equal to 1. however 0/0 can just as easily be 1 as it can be 2 because every number that we know of multiplied by 0 gives you 0 therefore a correct numerator. and if you take 0/0 as equal to 1 it is just one of the answers and its just as true that 0/0 is 2 or 3 or -1 or -2 or whatever. and 1+1=2 and I see no real reason why not to say that 0/0+1 is equal to 0/0. I know i would be burned at the stake if any mathematician would have their way (and to be honest I'm pleasantly surprised that a mathematician such as yourself chosen to actually consider this question rather than say it is nonsense)for suggesting it but I really don't see anything wrong with it at this point. especially considering that there is for example particle wave duality so one thing can be in two states at once. furthermore I wouldn't necessarily say that negative number to infinite power is an imaginary number at least not the way I understand what imaginary number is. It is definitely undefined even more so than 0/0 but i don't see it as imaginary (although I know it is not a number at all but rather a concept) if we would treat infinity same way we treat numbers then the concept resulting from it might not be same type of concept as imaginary number such as square root of negative number. (of course once again in this case I might be completely wrong like I said I was a bad student and what I'm suggesting is sacrilege) because no number multiplied by itself gives negative number but if you multiply negative number by infinity by taking only odd numbers you don't come up with a real number but with real concept and if you do the same with even numbers you also get a real concept. and yes if you apply the infinity containing both odd and even numbers you are not able to define if the number is positive or negative and this number would not only be undefined but also not on the number line as we know it. but that doesn't necessarily mean that it is like even root of negative number because in this case you have the answer already given and you are supposed to find the number that fits the answer number that not only doesn't exist on a number line but multiplied by itself is supposed to give you an answer that does exist on number line also it doesn't seem to make any sense as far as we know. now I'm the type of guy who would never say never but square root of negative number simply seems not to make any sense. while negative number to infinite power has some chance of being a real concept (even if not a real number) now the last thing for which I will probably be called insane or worse I'm not even sure if infinite root of negative infinity is a fully imaginary number or at least a concept. because if you take infinity of odd numbers the concept makes sense (even if it isn't a number) and yes if you take infinity of even numbers it is an imaginary concept. but if you take them both you are not able to determine if the concept is real or imaginary and it has a real part. I don't know what possible use any of this would have but we do have uses for one hundred percent imaginary numbers so maybe at some point we will have uses for all or at least some of what I talked about. and if there was something tangible that had something to measure where 0/0 for example applies then this thing would be not one position or size or dimension or whatever but many many of them at the same time and understanding this system would give us information about something unusual and who knows what kind of applications something like that would have. some scientist put 0/0 in the equations relating to black holes. now we don't know for sure if this equation applies also the denominator for this equation is 1-0/0 which can add up to any number including 1 and 1-1 is 0 . and since the numerator is sometimes non zero number it doesn't seem to make sense. but there are things in universe that appears not to make sense until we understand them.
