you rage you lose
>>700716494
They're both right. If you're talking fractions the teacher is right, but if the one pizza is bigger then the kid was right. There's nothing to rage about.
>>700716708
You should've blacked out the name under the picture.
>>700716579
Common Core... 'Murica.
>>700716761
The question is clear. "how is that possible?"
so he said how it was possible
>>700717037
I understand that. However that doesn't make the teacher wrong.
>>700717143
>were you there?
lol that's great
>>700717225
It does, because the answer is clear. There is a true and valid answer to the question. It shouldn't be a trick question, it doesn't say "assume the pizzas are the same size"
The teacher is wrong in this instance because the student answered correctly how the pizza could be bigger. The correct answer shouldn't be "it isn't possible" unless there is more to the question.
>>700716753

>>700716753
What is the old way? How would that equal one?
20 divided by 5 is 4, and two times two is 4, and finally 4 times four is 16. where the fuck does the 1 come from?
>>700717225
It does. He said a way that it was possible, he can't be told it's wrong.
>>700716579
this one is particulary nasty. I wonder what kind of major teacher have to pick to teach in the USA. Woman studies maybe ?
>>700717225
please do not be a teacher
>>700717225
the teacher marked the kid's answer as wrong. so even if they were both right, the teacher should kick rocks. And the teacher is wrong, because the teacher doesn't realize that a lower fraction of something bigger can be a larger amount.

2*2 is done first, so you have 20/5*4
/ and * have equal ordering, so 20/5 is 4, 4*4 is 16.
wtf is the old way? ignoring order of opperations, and doing 2*2*5, then deviding 20/20?
thats wrong. math has 1 way of doing it. i feel bad for the future of america if this is whats being taught
>>700716761
Wrong. The question is who ate more pizza, not who ate a larger fraction of his pizza.

>>700717997
Nvm, I see how this is retarded
>>700717568
I assume that they somehow think that you have to multiply 5 by 4 first
>>700716494
the question is "how is this possible?" not "is this possible?"
kid was right, teacher failed to frame the question in context. Beat that teacher senseless.

to cut a board into 2 peices, you do 1 cut. this took 10 minutes.
to cut a board into 3, you do 2 cuts. 2*10 = 20.
>>700717862
thats retarded. you first do the bracket, then go from left to right. (since there is no +-)
therefore: 16

You are wrong.
Actual maths suggests that you simplify the numerator and denominator

>>700717997
the action that takes time is cutting
>>700716753
Why do they even teach this?
Nobody writes questions this badly. If there is any ambiguity in your question, you're wrong for asking it in that form.

she did a task that took her 10 minutes. she was asked to do that task 2 times.

By old way, you mean "right way". Common Core is the single most retarded thing I have ever seen, and it actively contributes to the ongoing stereotype that Americans are all retarded.
>>700717879
since it is 20 / 5 (2 * 2) you have to do 5 * (2 * 2) before you divide by 20 because there is no "*" shown between 5 and (2 * 2) so you have to take it as a whole number first which is divided by 20

5(4) is implied multiplication, so it's subtly different than explicit multiplication like 5*4.
Implied multiplication is done before division and explicit multiplication.
>>700718412
so "the old way" is completely messing up the order of operations? great
>>700718341
Are you fucking retarded? It won't take any less time to cut the board just because you are cutting it more than once. If it takes 10 minutes to cut the board once it will clearly take 20 minutes to cut it twice, into 3 pieces. Fuckface.
>>700718135
that's stupid, once you have the bracket solved, the answer no longer gains any priority over any other part of the equation, it's been solved. idiots.

>>700718475
But there is no paranthesis at that point as you've simplified it as much as possible so it becomes
> 20/5x4
Since multiplication and division are on equal footing, you go from left to right, giving you 16. You don't factor a paranthesis, you eliminate it.
>>700717879
> Tfw when you are a yuropoo who doesn't understand what the hell Americans are talking about when using math cause they use different symbols
>>700718781
The only true answer here
20/5(2*2) = 1
20/5*(2*2)=16
>>700718475
Thats not a fraction, you numbnuts, and if you were to turn it into a fraction it would be (20/5). which (20/5)*(2*2) = (4)*(4) = 16. If you come up with one you were either taught incorrectly or are simply retarded.
>>700716761
the question asked who ate more not who ate more of their pizza, the kid was right 100%

This so much, remember when Russia bombed Georgia and muricans were loosing their minds?
Remember when they bought the whole "Sadam had direct involvement in 9/11, here are some JPGs to proove it!"

parentheses are to contain a separate but relevant equation as written in the root problem, the sum does not gain any priority over the rest of the quation once you have it. It's 20/5x4, which equals 16, no wonder you fucking apes lost the space race

The old way is going left to right, how else would you do it. You start with 20/5=4 then 4*4=16.
>>700716579
Since it only takes one cut to make a piece 2 pieces, and one cut took her 10, it would take her either 10 or 20, depending on weather or not you count her first cut.

this is spacial relation and the kid answered correctly.
the student judging by their handwriting, is still a young child under double digit age. you cannot ask a child who forgot to put "n" at the end of "than" to proof a test. he's going to assume the test is being honest with him.
he reasoned correctly that the only possible way 2/3 of a pizza is greater than 5/6 of a pizza would be if the 2/3 pizza was larger to start with.
that's spacial relation problem solving.
so the question says when is 2/3 > 5/6.
and he says when you have 2/3 of 2 and only 5/6 of 1.
and the teacher marked it wrong. he's not being a smartass. the test was being a smartass.

That's not exactly how it works....
It took her 10 minutes to make one cut....
So, if she takes another board and cuts it twice (into three pieces), at the exact same rate (10m = 1 cut), then it will take her 20 minutes to make 2 cuts...

He didn't answer it correctly. The pizza could be 1% bigger, and the guy still would not have eaten as much. The is a specific size bigger that the pizza would have to be in order to insure that the guy ate more pizza. The kid is wrong because he did not include this size ratio.

Teacher IS right, and 4chan is autistic. If she cut a half of the board into half again, cut would be half as long and take half as long to make. I guess you could argue she cut the board flat and just was really, really slow, but that doesn't make sense.
>>700719122
For those of us who actually care about math, there are two possible expressions here:
20/(5*(2*2)) = 1,
(20/5)*(2*2)=16
which ever you mean is essentially down to interpretation of whether division is first or the multiplication is. Unambiguous notation and unclear rules are the issues.
In practice, one would evalute left to right, so (20/5)*(2*2)=16 would be more likely assumed.
>>700717702
A lower fraction of a larger amount doesn't automatically make that quantity bigger. 3/5ths of 501 is still smaller than 7/10ths of 500 even though 501 is bigger.

But you must multiply before dividing. Also when an equation is part of a fraction you work it out before solving the fraction.

Both are correct
-Brackets/Parentheses/Braces/Unary operators done in order of nestedness
-Exponents
-Multiplication and division, done from left to right
-Addition and subtraction, done from left to right
Graduating High school and not knowing that subtraction and division are not commutative.

>>700720235
There is no precedence between the two, hence pemdas, bedmas or whichever fucking one you have can still be correct. They are the same 'tier', they come before additon and subtraction, which are also on the same 'tier'. You go left to right when dealing with division/multiplication and you go left to right when dealing with addition/subtraction. No trolling, no baiting, it just is.

>>700719313
Look at it like this
>>700720927
ofcourse you can, because there is a "implied" multiplication there. BUT, what I meant was, that there is no difference in implied, and normal mulitplication (as stated by >>700718781)
It doesnt behave any different, you still go from left to right, following the order of operations.
The problem is still badly written since it can be misunderstood, which should NEVER happen
>>700719357
>>700719480

There is a reason fractions exist. if you use a fraction instead of the divion sign it would be unambiguous. I mean it is now as well but it would make the problem clearer.
>>700718894
You are fucking retarded.
PEMDAS and BEDMAS are the same thing and Multiplication and Division are done from left to right. It doesn't matter which order they are in the acronym. If multiplication comes before the division in the equation, you do it first and vice versa.
>>700721320
that would be 20/[5(2*2)]

Either way you still multiply before you divide and you work out parentheses before anything else. 2x2=4. 4x5=20. 20/20=1
>>700717879
>>700717568
>at least going off memory of what I was taught
In this equation, two numbers are being divided, 20, and 5(2*2), 5(2*2) is essentially one term, because there's no multiplication sign explicitly written between the five and the bracket, it's part of the same term, thus the operation of multiplication between the two must be done first for them to be treated as equally whole.
20 / 5(2*2)
>could be written as
20
---------
5(2*2)
>the inside of the bracket is equal to 4, and 4*5 is 20... so...
20
------

Have you never seen a word problem before? Nothing about the kid's answer is even remotely wrong, and that teacher should be punished in some way for such a shit type question. Since your a math guy I will repeat the question and see if you aren't retarded. One kid eats 5/6 of a pizza, another kid eats 4/6 of pizza, how is it possible for kid two to eat more pizza? If kid two has a larger pizza, would it, under any circumstances, be possible for him to eat more pizza despite eating a smaller fraction of his pizza?
>>700720862
No, couldn't care less is basically saying you could not give a single fuck, that nothing matters less. COULD care less means you could, well, care a bit less if you tried - it's not the most insignificant thing. See what I mean, maybe it's just an American v england thing. Just seems odd to us is all.
>>700720060
its just too soon to talk about it
>>700721669
wrong, you dont multiply before you divide. divisions and multiplications have the same value (same as plus and minus) therefore: left to right.

Actually here is how you get 15 minutes.
Imagine cutting a perfect square, 1 foot by 1 foot, straight down the middle, leaving you with two rectangle shaped pieces. This 1 foot long cut took you 10 minutes. Leaving you with to pieces that are 6" by 1 ft.
Next cut, you cut one of the rectangle pieces in half, the narrow direction, so you only have to cut 6" instead of 12". 6" of cutting time takes 5 minutes.
So, you have one piece 6"12", and two pieces that are 6"x6".
With total cuts required, one 12" cut, and one 6" cut, that require 15 minutes of sawing to do.
>>700720594
No the problem is people are simplifying the paranthesis, then not eliminating them, which is the point of simplifying them to begin with. There's no one that is decent at math that would see it as:
>20/5 (4)
Because the paranthesis is already eliminated giving you
> 20/5*4
Which is 16.

Clearly since the board has already been cut in half any additional cuts will take half the time. ie 10 minutes becomes 5 minutes because the board is 1/2 as thick!

>implying intensifies
This entire thread. I blame notation. The associativity of multiplication and addition in a field leading to sloppy by efficient notation (dropping parentheses). It makes expressions simpler, but for people who just memorized rules--90% of this thread, it leads to something that requires _debating_, jesus christ.
We have failed society.

I'm actually (and seriously) a fan.
American primary schools don't teach math today. They teach calculation.
It's not important to be able to multiply numbers quickly. It's much more important to know what multiplication is on a fundamental, intuitive level.
>>700722081
