Let's take that thinking and put it towards language. In language, we're constantly evolving it to make it easier to communicate with each other, and this has resulted in things like slang and text-speak. With language, you're taught the proper way and people come up with the slang and such themselves, and maybe eventually that becomes the norm. So now tell me, how is that any different than with math? You learn basic language components and structure early on in your life because it helps to have when you get to the more complicated parts of language later on, and that's the same with math. These are still the basics, and if you change the basics because it's easier for them now, they're going to have trouble later. You can still teach a kid that addition and multiplication problems can have the numbers switched and get the same answer, but letting them know that there's a reason later on to keep it consistent is important.

@revanreborn1219

6 жыл бұрын

Rukifellth On that we can agree.

The great irony is that they're marking students wrong for something that shows that the kid actually understands the material and is capable of improvising with it. If the student can only follow the steps by rote exactly as you have specified at all times, then there's a very good chance they don't understand and can't apply the information to novel situations. But worse, I would argue that "5*3" is grammatically ambiguous about grouping. The way *I* have always read "5 times 3", I interpret it more like "5 multiplied by 3", not like "3 groups of 5". Indeed, interpreting the phrase "5 times 3" to mean "3 groups of 5" sounds like archaic and stilted old-timey English to me, and does not roll off the tongue at all. So if I were one of these knuckleheads who thought it mattered which way they grouped it, I probably would have marked the *other* answer as incorrect. But seriously, there is no "correct" grouping of 5x3 in the abstract. To mark them wrong here is just factually wrong, because the commutative property is a fundamental algebraic relationship. Getting pedantic about notation with 8 year olds to trip them up with technicalities is just sick, especially when that notational quirk is just an arbitrary convention chosen at random and is in no way implied or infer-able from the usage of that notation, and doesn't even affect the result. Again, I would argue that what the child did is more intuitively correct.

The foundational skills of problem solving vs "repeat after me" . Yes there are strict formulas...but most are not as strict as it seems they are teaching in public schools. And even worse....they are taking simple formulas that work great as they are, and complicate it for no good reason. It's a mental experiment of redirection. So glad I homeschool. Thank God. ❤

Fester Blats, third graders? You are saying THIRD graders? Are you serious? Since when does it take more than 2 years of math to get past addition? That's fourth month material, first year. Usually around that time, children are also supposed to know that the operations of multiplication and addition are order-independent - if they aren't told, they will recognise that themselves within months. And well, thing is, the language itself is ambiguous because the operation is commutative. "5 times 3" does not really correspond to any particular real-world experience. It could mean "5 groups of 3" just as well as "5 repeated 3 times", with latter being merely rearranged to better correspond to mathematical notation, and linguists don't even know for certain which it is. Indeed with non-commutative operations, it's kind of common that the first operand is the primary one, while your (and teacher's) interpretation suggests that second operand is the primary operand of multiplication. Another point to be made is that the student is being punished for being resourceful while being correct, because adding 5 three times is easier than the other way around, and punishing that seems like a terrible idea. School is supposed to develop universal skills, like creativity, critical thinking, logical reasoning, ability to combine these skills to gather and process data and arrive at new conclusions. It's often observed that it doesn't succeed at doing this, that often it quenches creativity and has you memorise an ever growing set of recipes that allow you to handle specific situations, but not even slightly different ones, recipes that are quickly forgotten once they fall out of use, leaving the person rather helpless. If you were looking to see why that might be the case, you have a real tangible example right here. You might object, that if we don't punish creativity here, you're not gonna know whether they understood that not all operations are commutative. But that's the wrong way to go about it - you just need to test that separately by including test cases where they would mess up if they failed to grasp that.

It is the foundation for the more complicated math. If students of the more complicated math do not have the comfort of the simplicity in the simple math, if basic addition has been made overly frustrating, how will they learn the complex stuff? And, if they can't learn the complex stuff, God help us when we have no competent engineers in 20 years!

Me too. Cause my teachers reads 5x3 as 5 MULTIPLIED BY 3. So 5 is duplicated 3 times instead of the vice versa

"Common Core" is incorrect. This is correctly expressed as 5+5+5. According to pemdas, the calculation is executed from the left. The first term (5) is "multiplied" 3 times. Not the other way around (commutation rules aside). If you don't believe me, substitute in a division operator and attempt to apply the same logic. The error here is, they've tried to introduce a semantic of "associativity" (specifically for the multiplication operator)

@jsr4096

Seems we're getting into semantics, but okay. PEMDAS doesn't explicitly call for execution from left to right, but is rather define an order of operations which would --otherwise be evaluated from left to right--. Fair enough. Let's take the 2÷5*5÷2 portion of your expression. The reason, is that PEMDAS is moot here, as multiplication and division have equal precedence. Executing the 2÷(5*5)÷2 (mult. first) yields a different result to 2÷5*5÷2 (from left to right). So if it "in no way follows left to right", how am I to know which order to execute this? While there are uncountable examples of commutativity (e.g. the example you gave), what do you do in situations where commutativity is not applicable? Perhaps I've misunderstood you? Apologies if so.

A teacher, wanting to get some paperwork done during class, gave his pupils the task to add all the numbers from 1 to 100 together. Before he could sit and open his paperwork, believing that they had enough work for the whole hour of the class, a single boy said: "Five thousand and fifty". The teacher asked how did the boy know it so quickly. The boy explained that by adding the first and last number, 1 + 100, he'd get 101, by adding the second and second to last number, 2+99, he'd again get 101, and that there were 50 such pairs, resulting in the total 5050.

The second example of yours sounds a lot more clumsy, and sounds like the way someone would say the line if they were writing a script for Yoda. It sounds nothing like the way I would expect anyone to naturally talk. A better example would be the "don't end a sentence in a preposition" rule, that many teachers insist you follow. It ends up requiring you to beat around the bush to say simple sentences, and rearrange the preposition to a place that sounds so unnatural, and makes it so much more complicated to follow the sentence. You can end a sentence in a preposition, it is just called an adposition instead.

this is partly why I hated math in school and thought I was bad at it but when I took remote learning in college and the only grades came from in-person tests, I was able to get over a 100% in the class.

In high-school, I was nearly expelled for refusing to 'show my work' when factoring polynomials. I had developed a technique where I could do in my head, and it always worked. In Mr Takahashi's math class, everyone showed their work. I tried to 'show my work' by using my technique, but he couldn't follow it. "Do it the standard way!" The teacher was old-school, so my refusal was a discipline issue, not a mathematical one. I made an appeal to the school counselor to prove my point. They tested me by having my teacher write problems on the board, and I was to call out the solutions. He wrote over 250 problems, including some that were deliberately badly formed, which I caught as well. At one point, I was calling out answers as quickly as he could write the problems. He was mad. He didn't know how I was cheating! I had to present my technique to my math teacher, a school counselor and the Vice Principle that I had learned to factor in my head and to prove it, I walked them through the process. They all understood the process after that, and the VP thought it was a 'clever trick'. After a few more examples, my teacher just left the room, silently. I was excused from showing my work, but I still had to pretend to do it, for the sake of other kids! BTW, the 'trick' is to ignore some of the terms, and look for patterns of sums, differences and products of the whole numbers. If there is a 13 and a 42, then 6+7 and 6*7. You also know that everything is positive, as 6 + 7 = 13. If you had -5 and a -36 then 4-9 and 4*-9 is afoot.

I was put off maths for years by a moronic teacher because she always marked me down even though I got every answer right just because I layed it out vertically and not in a horizontal line like she wanted. Back then I thought "I got it right and its still not good enough, I tried so hard to get everything right, I'll never be good enough she hates me" because that's how little kids think. It ended with a massive argument between my dad and the school Turns out the only reason they could come up with was it 'wasn't policy to teach students to lay it out vertically until year 4' my dad was furious.

It depends on what you take into account. If you add 2 and 2 you're by necessity the fifth thing in the equation. Another Example is 2+2 has to exist in context of what isn't those 4 things i.e. space thus being a fifth entity in the equation. 0 is equal to 1 when considered in isolation, 1 in contrast to 0 is 2 things and so on.

"5x3" is the same both ways. If it stated "Three, Five Times," then this would make sense. But 5x3 and 3x5 are exactly the same. It doesn't matter whether you envision it as 3 groups of 5, or 5 groups of 3. There is no preference information included in the statement "5x3." Common core is attempting to assert that '5' is always the number of groups if it comes first, but that's arbitrary and false. For this reason, common core is Wrong, and should be abandoned.

That happened to me in college....but not until then. Unfortunately k-12 was already forcing "my way or your wrong" compliance mentality in the early 2000s. But it was inspiring to have a teacher tell me I was doing it a more efficient way (in college) like you did...and they didn't understand until I explained my work. Lol But then they said they would use it and asked to show the rest of the class. One of the best moments of my entire experience in the educational system. But I'm extremely grateful I now get to homeschool my children. Praise Jesus ❤

Back in elementary i sucked at multiplication and instead used that method of addition when i came across certain multiplication i couldn't remember and in turn as i continued to use it i began to remembered the answer and eventually came UNDERSTAND how multiplication worked and with that understanding i could do multiplication with ease. So from the way i see it that child is merely taking a different approach to remembering the multiplication by trying to find out how it works instead of just trying to outright memories it without understanding.

That's what worked with my special needs kid honestly. I didn't learn that way myself. But it was a logical method. We actually would reinforce it in homeschool by practicing with simple logic skills to stretch the brain so-to-speak, then move into math. For multiplication grouping and counting are all you need IMO. I started teaching that concept very young to my child though, but that's why I think repeating it through the years from being a toddler is why even though moderate special needs he was able to comprehend it ahead of some of his class even. Meanwhile the teachers at the Charter school (at the time using a useless online method..) were not bothering to teach it at all...and I learned that others commonly expect kids to remember and regurgitate times tables w/o comprehending the concept. Now we do times tables because he likes the fun songs we found for that...and it was something we worked up to. A lot of public education is whack for the order in which they teach things as well. Some charter teachers told us to work on decimals and place value first, for example but I found this to be too confusing and not necessarily logical. So we skipped it, but learned mult., Division, fractions early, and when we came back around to the rest it was a breeze. Because the pathways for critical thinking were there, and it was less confusing with his brain a bit more developed. They teach history in odd ways too....all over the place and not as linear as it should be IMO. But also they lie a TON in history and social studies. Especially when considering how corrupt the process is with our government. The forefathers were not Christian, but anti-Christian and actually mounted attacks on real Christians like the Quakers. Christians also did not start the Spanish Missions...those were Catholics. But it's interesting how much they will twist things to create a narrative that works for them vs the people. God speed. ❤

The commutative property guarantees the answer will be the same, regardless of whether it's ab or ba. However, 3x5 and 5x3 are not the same math problem. The former is "three instances of five added together", while the latter is "five instances of three added together". That principle is the basis of all further mathematics, and should always be taught before shortcuts such as the commutative property. Math isn't always about what the answer is, it's about the understanding the concepts behind the problems in order to understand how you arrive at the answer. You could tell a first grader "10 squared equals 100", and they could memorize that answer and spit it back to you whenever you asked them. Unless they understand WHY, though, then the entire thing is pointless. Instead of memorizing multiplication tables and spitting them back whenever asked, students are learning how to understand the concept behind multiplication before anything else. If anything is indefensible, its the fact that we used to teach simple memorization instead of teaching principles and concepts like we do now.

You're correct, if the "story" you're referring to is solely the answer. 3x5 and 5x3, although they yield the same answer, are not the same problem. Even still, the point is completely moot in relation to the story presented in the video, since the problem didn't ask "what is 5x3?", it asked the student to use the repeated addition strategy to solve 5x3 (source: the paper itself i.imgur.com/KtKNmXG.png). Using repeated addition, 5x3 is not 5+5+5. It's 3+3+3+3+3. The student failed to correctly use the strategy being stressed in the example, as is further explained by the student's other error visible in the image I have provided. Common Core stands, the student was wrong from both a conceptual perspective as well as the practical application of the concepts he/she was supposed to be using.

It's the curriculum the schools choose that causes the problem. The state standardize test don't care bout the "shortcuts" used, they just want the correct answer. But the teacher is stuck with the book lesson, and grading on that scale. So if a lesson states that aXb=b+b+b+..+b and the student shows the work as a+a+a..+a, then yes they are wrong. It's along the lines of this question "use a blue crayon and a yellow crayon to show what happens when you mix the two colors." You have a blue, yellow, and a green crayon. You know the end result is green, so you just use that. But you are wrong, because you didn't follow the directions. Silly, yes. But it's testing a skill, not an answer.

Multiplication also adheres to the commutative property, it only doesn't apply when there is also a arithmetic function in the statement so (8+1)*2 is not equal to 8+(1*2) but that is why there's a formal order of operations that always applies absent parenthesis to indicate otherwise. He is correct, the commutative property dictates that a*b = b*a, understanding the commutative property along with when it applies is an essential tool in advanced algebra, discrete mathematics, trig, and calculus. You do kids no favors teaching them things that must later be unlearned. As for evaluating correctly to 4-5 verses 5-4 is a bad example. Subtraction written that way is short hand for addition using negative numbers the commutative property doesn't apply there because you're essentially saying -4 is equal to -5, the way 5-4 should be written is 5+(-4), now suddenly we see that the commutative property does indeed still apply to subtraction. 5+(-4) = 1 = (-4)+5 All three statements are indeed equivalent.

having an actual structure to learning, instead of just memorizing a multiplication table is better. period. using your brain to think instead of just memorize answers leads to better educated, more intelligent students. its the OPPOSITE of what youre describing. instead of indoctrinating them with the answers without telling them how those answers are arrived at, its teaching students to THINK and process the information rather that regurgitate an answer. sure, there is a framework and it seems stupid to mark them wrong for arriving at the wrong answer the wrong way, but teaching people to arrive at an answer in a way that the next lesson builds upon, and the next lesson after that, etc etc leads to, like i said, a better education. no, its not the way you were taught, but american schools suck. they do. we are trying to improve that, and a more structured, more intuitive system is what other countries who have far better educations systems have been using for a long time.

If you're taught that in mathematics, 5x3 by strict definition means 5 sets of 3, and 3x5 means 3 sets of 5. Then when asked on a test to show your work for what 5x3 equals expressed as a sum of numbers, if you put down 5 +5+5 =15, you're wrong.

Strict definition is an exercise in semantics. Because given the property A * B = B * A; the strict definition that you described is semantically equivalent to 3 sets of 5. The strict definition would be an important nuance for linear algebra but for this application; penalizing the child for a disagreement over semantics is a real dick move.

I wanted to bash the idea at first. But Say if had a construction project and a certain part of the structure that I was building called for 3 5ft length boards and I instead cut 5 3ft length boards..

British maths teacher here with 25+ years teaching experience in secondary schools. (Aged 11 - 18). As a maths graduate I know there are many ways to answer a lot of maths questions. I can think of 10 ways to answer 125x45 for example. Any student who gives a recognisable, correct method to get the correct answer will get the marks. BTW the "grid method" for long multiplication (that Americans call common core) is a perfectly valid method, as well as the traditional "column method". Some kids prefer one methpd, some the other. Others have their own methods, and if it works for them - great.

Because of reflective property, 5*3 = 3*5. The students should not have points reducted for something as trivial as "it's five groups of three, not three groups of five."

As a native spanish speaker, this will be tricky for me, since in spanish, the first number is the one we are multiplying (cinco por tres or three times the # five), so this means that the real answer for us will be 5 + 5 + 5, but if you read it en english, 5 * 3 (five times the number # three) so it makes sense for me that the answer will be 3 + 3 + 3 + 3 + 3

Your picking apart the curriculum which was written by people who actually know WTF they are talking about.

Anon54387 gosh then why do they say “use different strategies”

In multiplication and addition operations of whole numbers, it isn't a matter which constant is left or right the only matter is values. The fact that you multiply 5 three times or 3 five times is based on interpretation only if it is a word problem question. If it's arithmetic it's correct either ways.

Why do they even need to write it out. Isn't the entire point of the multiplication table to not do that. I understand if it was like the first few practice problems, you do the proof a few times then you get the short cut that's how that works. What do they need to reinvent the unit circle and define sine, cosine and tangent for each and every problem when they do trig?

Teaching multiple ways to reach the same answer is effective teaching. However, penalizing a student for thinking differently than they are told to think is outrageous. I'm so disappointed that this is what teaching has become. They are encouraging group think. Can anyone see how dangerous this is!

No kid should have to be punished for actually using the right formula, much less using AN EQUIVALENT FORMULA. If the formula gets you the right answer every time and it's simplified and thus nets less possibility for mistakes, USE IT, or you're only making things harder for yourself. EQUIVALENT FORMULAS ARE INTERCHANGEABLE. That is why they are equivalent.

And this my friends is called inefficient. Doing more work rather then doing less work for the same outcome.

Disagree. Teaching a student what the question actually _means,_ and teaching the student that asking the question a different way can mean getting to the answer a different way is immensely valuable... and will SAVE them a lot of grief and frustration when they get to much harder concepts down the road. Teaching students _how_ to think and not just _what_ to think is far more "efficient" than just telling them, as you apparently would, that 5X3 is the exact same things as 3X5. Had you been given an "efficient" education when you were younger, you'd already understand this. We're trying to help these kids avoid thinking in circles like you're doing when they're your age.

Efficiency... Interesting you use that word as America's education system is anything but efficient. Yes, you're right that it "teaches" students how to think, but that's the problem. It TELLS them how to think, not letting them apply their own methods to solve issues. (Being a CSE Major, I have found my own education has crippled my ability to think through solutions.) The education system is so normalized that students who don't learn in a conventional environment are lost, just like I was. I wasn't a good student, not from lack of trying but because the system I attended forced a singe learning method on me that was highly inefficient and extremely stressful for both myself and my father. It's a system that forces everyone into a tiny box and cuts off the bits that won't go in or don't fit, and it's not a good system. It never was, but that's the way it's been and that's reason enough to keep it around in the eyes of politicians and boards of education. I'm also finding as I've grown older that people think kids are stupid, which isn't true. Not in any sense of the word. In fact, they're smarter than most adults but the "old guard" (meaning adults like you and I) actively, and sometimes intentionally, stifle that intelligence. Everywhere I look, I find some mention about how kids need guidelines, rules, and strict enforcement. How students need to adhere to a set of standards and anyone not meeting them is not only lost in the dust, but considered a complete dunce. Like learning a different way or having a different method from "the norm" is somehow a mark of shame or rebellion against a system that is, in honesty, completely broken. Kids aren't stupid, they're just inexperienced. Maybe we should treat them like that instead of labeling them "dunce" until further notice. Back to the immediate matter: 5x3 = 3x5, this is simple math equivalency. I ask you this then: is it more efficient to think "Oh, it's 5 groups of three" or "three groups of 5 = five groups of three, so I can do three groups of five and get the same answer." Do remember: This is math, not English. It shouldn't have been marked wrong, despite what "educators" think. If they wanted the student to think of it a different way, then make a note or tell them, but don't mark a right answer wrong because the method wasn't what was expected. In Computer Science there are literally hundreds of ways of doing one action. Some long, some short, all are considered right because they work. Math should be the same way; If you have a method that works, use it. Rome wasn't built in a day, nor by politicians. P.S. Sorry for being wordy, but this is something I'm rather passionate about.

Scors4 Couldn't agree more! But I think that's changing, maybe in the next 20 years or so we'll be changing how children are schooled. The governments won't change it, of course, but the private sector will improve education methods, and then public schools should follow suit.

It is also a language situation, in spanish you read it: "cinco por tres" or "tres por cinco" the word "por" just indicates the operation in this case multiplication, that is enforced by the commutative property of multiplication, so in spanish you know there is a number being multiplied by the other. Division on the other hand has no commutative property, so 5 diveded by 3 is different than 3 divided by 5. So, when you use the word "times" to express multiplication, and you evaluate the student as presented in this video, you are evaluting english, no math.

What about commutative property? Both answers should be considered right.

It is a common mathematical law that a • b = b • a. That kid was right.

I had it backwards, 5x3 in my head meant 5 plus itself 3 times.

If you ask me, it makes more sense for 5×3 to be the same as 5+5+5. To me, it's like saying you're taking the number five, and multiplying by 3. Or adding 5 to itself 3 times. Idk. It's hard to explain. All I know is that this is bull.

5x3 is 3+3+3+3+3 fundamentally in math. You cannot switch it to 5+5+5 because that is wrong. When you get to higher orders of math such as calculus and algebra you can't swap the order around just because its easier, it leads to an incorrect answer. Try multiplying matrixes both ways, you will end up with different answers. One will be right and one will be wrong. This is why typically higher order math tests such as my calculus exam less than a 1/3 of the points given on the essay questions were for the actual answer. The majority of the points were for showing how you got to that answer.

You say it doesn't matter. But for the millions of engineers and other professions that require you to understand higher order mathematics it does matter. The point is to prepare you for a job you may need the skill for in the future. Just getting the right answer to 5x3=15 is never going to help you in life, especially when we have a calculator. It's understanding the concept of multiplication that will help you in life. Although I think the common core method is extremely stupid, this is one place they get it right. If you think the only thing important in math is getting the right answer, you dont understand mathematics at all. Not to mention if you think you can magically get the right answer everytime with this method in higher order mathematics, not only do you not understand math, you are probably very dumb. You can't just magically get every answer right every time. That is why we learn how to solve problems. Math is extremely straightforward, but at the same time becomes more and more complicaticated the further you get. Of course creativity is important in math, but if you can't even understand a fundamental concept of how multiplication works, you won't get further than calculus before you hit a wall. It's much better to teach students the proper way of multiplication early since its not any more complicated. Whats more complicated about it? You say its more complicated than it needs to be, but all it is understanding the order of which to multiply. The order of which you need to multiply matters at higher levels, and since its extremely easy to teach someone this way of thinking at an early age I believe it will help them since its no more complicated than the other way. However some of their teachings are more complicated and just confuse students. But teaching them that there is a difference between 5x3 and 3x5 is not complicated at all.

Florida did so to the detriment of Florida's kids. Not conditioning kids how to more easily handle more andvanced math can't be good thing. this question was *not* testing the kids comprehension of the commutative properties of multiplication in the simplest of terms, if the event it where about that both answers would have been correct

JCaesar That not how common core works. Common core is actually a higher set of standards than what states had before. You call it a broken program yet you have no clue what it is and how it functions.

In the great words of Stewie Griffin "It doesn't matter how you get to the end of the rainbow as long as you beat the leprechaun".

Even back when I was going to School,whether it was writing out long division or whatever. The procedure was as important as the answer.

5x3=3x5 Proof: 5x3=3+3+3+3+3 =15 3x5=5+5+5 =15 5x3=3+3+3+3+3=15=5+5+5=3x5 Therefore 5x3=3x5. Is there really need for proofs to explain as to why the kid is correct? Ffs

The reason is actually pretty simple. Because (at least for me) multiplication and division are leaned around the same time, teaching young children that you can swap multiplication, but not division,can be confusing. Also, the simple term for 5x3 is "5 of 3", which again, could cause confusion in young kids. I see where you are coming from, but if you take into account all factors, you can see why it was done

Thats ridiculous, it strips away the inventiveness and creative aspect of mathematics from a young age, math is meant to have multiple forms, many problems have multiple proofs and ways to solve them and you shouldnt be restrained to one way.

I didnt grow up with common core but I had a teacher in middle school who took half points if you didn't write it out exactly how they taught you and I was already struggling with math. I got a 50 because I forgot a step in her method meaning all my answers were right. If you're reading this ms.laird, screw you

loradreamer12 I had a similar issue in that I was naturally great at math but kept failing because I had a hard time writing out all the steps, or not as well as they'd want me to. I'd see a problem and just _know_ the answer in my head but noooo, I gotta write it out. Sometimes trying to write it out would result in me fucking up at some point during the process and I would have been better off going with my instinct lol. Man, fuck those teachers. At least I answered it right.

That's stupid as shit because in College if you manage to get the right answer you always get full marks as long as you show all the work you did.

I would get it, if this was some kinda word problem... and you needed to write how many groups there were, or the sizes of all groups after some shuffling around like "Each group got 2 more members" But otherwise writing it out like that is pure lunacy once you get to double digit numbers. Now class show your work for 15x1, and if you mess up with the amount of 1s the question will be marked wrong.

I found this looking 4 help to teach cc math to my child...and this is exactly how I felt

Your kid is actually brighter for choosing the simpler way.

Why was this in my recommended?

Dan Brioli or they're making the whole thing up. First of all there's no such thing as a "common core test"; common core refers only to a set of proficiency standards, not any particular curricula. Secondly, this smacks of "aren't you OUTRAGED at this?!?!" that's usually a dead giveaway the storyteller is presenting an outright lie or very specifically edited facts in a heavily misleading direction so as to be, effectively, a lie. Until I see the actual test paper and hear the actual teacher's side of the story I'm inclined to believe it's fake.

Yes. Why, indeed..?

They also do things now in college that emulate, it. Instead of answering true or false, and moving on to the next question quickly, you had to make sure they didn't rearrange the order of the false and true choices. For example, true was always thought to come first but I got marked off a couple times failing to realize they switched the ordering. Now it is, FALSE or TRUE, with false being the first choice.

Is it just me or is 5 x 3 more naturally seen as 5 + 5 + 5 over 3 + 3 + 3 + 3 + 3 anyway? Like, isn't it just a natural inclination which way you see it in the end? wtholyf
