If you don't understand "zero" I am not going to let you drive my car because you won't put gas in the tank. I'm pretty sure that farmers that over-wintered animals understood "nothing" as well. The stockpile of food for the animals and the other stockpile of food for the humans could get empty before spring. That would be a horrible disaster for the people depending on it. They either understood "running out" or they died. I don't believe this "didn't have the idea of zero" stuff. And empty plate, and empty cupboard, an empty barn, all of these were just other names for nothing.

Farmeryeti I think that most people intuitively thinks of 0 as even, but after learning more about 0 and how it acts in a weird way in many cases, like how 0 is neither positive nor negative, and how you can't divide by 0, some people might start to question whether 0 is actually even or if it's neither even nor odd. Apparently it does fit in well with the even numbers though.

I honestly always thought zero was even because of when I was like six and we would line up in pairs at school, I concluded that zero was even because odd numbers always have someone left out with pairs, but even numbers don't, and since 0 doesn't have anyone left out it must be an even number.

+Arc Kocsog The only reason for that is to make profit for the casino. When you bet on even, and it's correct, you get to double your money. But there are 18 even, 18 odd and one zero on the board IIRC (37 possible outcomes in total). So if you put M euros on it, the average amount you get back is: (18/37) * 2M + (19/37) * 0 = 36M/37. So on average, you always get less back than you put into it, and the 1/37 left over is the profit for the casino. Another way to visualise it: say there are two persons gambling, one always puts €10 on even, the other puts €10 on odd. For most runs, the result would be even or odd, and the casino wouldn't gain or lose anything. But for on average 1 in 37 runs, the outcome will be a zero, and the casino will get the complete pot of that run. The only way to win with the roulette, is to not play it often. When you play it only a few times in your life, the final result will not get the chance to average out (and hopefully to your advantage).

What ever number/counting/completion system you use, zero is always the higher receiver in the system, while it's higher emitter/receiver completon changes as we change our counting system. (Completion - the digital sum of all the numerical elements in the number system. Completon - two numbers, one of each type(emitter and receiver/odd and even) that add up to make the completion.)

coolguy 284 If you are talking about the modern definition, sure, but the historical origin is far more complicated than this. In reality, what happens is that you draw a circle and then a triangle using a central angle. There are many limes that have some special relationship to the circle, e.g a tangent line or secant line. The ratios are then defined in terms of how the special line is parametrized by the angle and the radius of the circle. Only a few of these ratios are taught today, though, which are the sine, cosine, tangent, cotangent, secant, and cosecant.

The addition of odd and even numbers is quite interesting as well. When adding any even number to an odd number, the answer is always odd. But adding any odd number to an odd one gets an even.

I always thought it was obvious that 0 is even, if you have an even number and subtract/add 2 your new number will also be even, so if we start at 8 which is even, then subtract 2 = 6 (even), subtract 2 = 4 (even), subtract 2 = 2 (even), subtract 2 = 0 (even?)

Al-Khwarizmi (or Al-Juarismi) was not established in North Africa: he lived and worked in Bagdad in the IX century and is mostly famous for his compilations and contributions to Algebra (he gave its name to this branch of maths) and Arithmetics among others.

Well, zero IS congruent to 0 Mod 2, which would be my definition of "even." :)

Mark Stump I think you mean 0 is congruent to 2 (mod 2), as congruence works like this, if a mod c = b mod c then a is congruent to b (mod c). You are right in saying 0 is congruent to 0 (mod 2) but it is also congruent to 0 (mod 3) or 0 (mod 5) etc. Just wanted to let you know :)

Mark Stump Thank you for clearing up the misconception. I thought you meant if for all natural numbers x, if x is congruent to x (mod 2) than it is even. Now I see you meant if for all natural numbers x is congruent to 0 (mod 2) than it is even, which is correct. Although you could have made your definition even better by just saying if x mod 2 = 0 than x is even, which is the same as both your's and Brady's definiton. :) And I do think 0 is even because it is a multiple of 2. Its kind of interesting to see whether people choose division or multplication to define even/odd numbers.

Jeevan Devaranjan It's the same congruence class and the same set of integers! Still, you had me worried for a few seconds: I'm old and senile, but I know how it works. I'm saying if "a" is congruent to 0 mod 2, it's even. (My proposed definition) If you think this definition fails, show me an "a" that is congruent to 0 mod 2, but isn't even... or show me an even number that is not congruent to 0 mod 2. I said nothing about congruency to 0 mod 3, 4 or 5... if we did have the word "threeven," of course I'd want a similar definition and I'd want to include 0 again...so it'd be even AND threeven. This doesn't bother me; I don't think it should trouble you. Surely you don't think 0 should be considered throdd!?

+salaciousBastard Basically if f(c) = ?/0, then you take a limit of f(x) as x->c, and that would be the answer. Most of the time this equals +- infinity (or a complex infinity), however, if ? = 0, then it could equal any number.

+E_M_E_T So basically, what you're saying is that it's both infinities at the same time. Wouldn't that simply mean that they take each other out, just like numbers with real values? I think I'll keep saying that it's impossible, because 0 isn't something that actually exists. It's an idea of nothingness to help with calculations.

+E_M_E_T Infinity is not a number. Nice try, though.

As a biologist, Here is how I see it. Even things means in pairs, like your ears, you have a pair of ears, or feet. If you can write a number as equal parts in digits. 12 can be written as 6+6. 2 can be written as 1+1. For 0, it is not a a pair of something; in my arrogant opinion, you cannot have 0 pairs. Thus, 0 is not an even number.

Plot twist : they were explaining that "is zero, even a number".

If you divide by n such that n is a divisor and n approaches zero, you can only take the limit of that expression. For example, the limit of (x^2 - 1)/(x + 1) as x approaches -1 is - 2.

He is referring to an even "number". 0 is an even number. 0 is also considered to be both "even and odd function".

I've always seen zero as "genderless," unless a larger number ends in zero. Then the zero makes that number even.

Think of Zero as a mathematical fulcrum and it begins to make sense: the transition point between negative and positive numbers certainly exists, in that one might even model it in this way, but it is not of either realm in any real sense. As such, Zero’s adherence to rules can only be described through unusual behaviors, some of which have no finite boundaries. Understanding Zero and all that it does and doesn’t mean further helps in understanding Nil (or Null), which is the absence of even the concept of a given thing. Nil is like removing the foundation upon which counting MIGHT occur, whereas Zero has that foundation yet does not make use of it.

In terms of cows and sheep, I think they'd say 'none' or 'nothing' or 'no', that worked as a proxy for 0.

Zero is infinitely zero.

When I start to teach number theory in 2nd grade, we Rach even and odd numbers using the number line. We don't teach even plus even is an even as they don't know how to add. I then teach that zero must be even since it is between -1 and 1, both odd numbers.
