6÷2(1+2)

3 × 3 = 9

9 also. 6/2 is 3, times (1+2 is 3)

so 3 times 3 is 9. Britfag here and my year 3 teacher taught me well.

It's 6 asswholes.

Parentheses go first, so 1+2=3, then 6÷2*3. Multiplication before division, so 6÷6=1.

6 divided by 2 = 3
1+2 = 3
3 + 3 = 6
ez

That would be 9.

>Multiplication before division
Except no, they go at the same time, so you go from left to right, doing the division first. It's 9.

Math teacher here.

PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction

6 / 2(1+2) - Parentheses: Add numbers inside
6 / 2(3) - Multiplication: Multiply 2 and 3
6 / 6 - Divide: Self explanatory dumbass
=1

It's 1 you inbreds.
>>
21
>>
>>719939474

You're a shitty math teacher then.

PEMDAS doesn't discriminate between M/D and A/S, you just go from left to right at that point.

Somehow i got the answer Kentucky

>>719936082

"The answer is that this is a badly-formed sentence. ... You can make claims about conventions and what is right and wrong, but really the burden is on the author of the sentence to put in some commas and make things clear. ... Math is not marks on a page. The mathematics is in what those marks represent."
>>
M/D are interchangeable but the multiplication in this case would come first as it's still a part of the overall bracketed sum. Answer is 1

parentheses take priority

All of these fucking threads boil down to this; it goes as follows:

Anyone who says otherwise is an uneducated, third-world nigger.

Definitely got 1. Order of operations, niggers.

>>719938320
Incorrect. Order of operations. It's 1. Inside parenthesis first, then multiplication, then you divide.

OP here. listen, in order to stop all of this PEDMAS bullshit, we have to argue about how PEDMAS works. I was taught PEDMAS, but others was taught

We need valid points, and proof to back them up.

>>719940725
You are right Anon. The answer is 9, not 1.
Multiply or divide, left to right.

The real Question:

100 - (100 - 1) = 99?
100 - 100 - 1 = -1?

The expression is poorly defined... it comes down to whether you read it as:
6/{2(1+2)} = 1, or
(6/2).(1+2) = 9
I'd be inclined to interpret the expression in the first way.
>>
>>719940366
You are correct. I would only add it is M or D; A or S; LEFT TO RIGHT!!!

6÷2(1+2)
6÷2(3)
3x3
9
>>
>>719941476
Your expansion isn't correct. If we replace the numbers with variables:

x - (x - y)
= x - x + y
= y

Therefore,

100 - (100 - 1) = 1

The way it's set up is all retarded...
Only an idiot would write a problem like that.

How retarded do you have to be to not get 9?

multiplication or division first or just what comes first.
>>
Jesus Christ 6/2(1+2) Google = 9
>>
>>719940528
What are you going on about? Multiplication and Division get done at the same time, left to right, addition and subtraction are done at the same time, left to right.

3x3=9 but 3/(1/3)=9 does as well. Just like 1+2=3 and 1-(-2)=3. They get done simultaneously with equal priority because subtraction is synonymous with adding negatives.
>>
>>719944011
It's what comes first.

It's a fucking fraction you retards. 2(2+1) is the denominator.

PEMDAS is for second graders. Just follow the parentheses from inside out, as in: (6/{2[1+2]})

old fags will say 9.
new fags will say 1.
Formating is unclear. Math as a language,is only sensible if its syntax is concise.
>>
>>719939959
>>
>>719949561
It's only 9 if you read like a retard. In order for the answer to be 9 the problem would have to be as follows
(6/2)(2+1)
But it isn't is it. The 2 after the division belongs in the denominator of the fraction, not the numerator, so

6/(2[1+2]) is the correct way to read the problem
>>
>>719936082
6 / 2 * ( 1 + 2 )
and result i got is 9
i am a newfag here in the whole 4chan. srsly the hell is wrong with you guys? desinformation is this seriously ? fuck the future is going to be a piece of shiet
>>
>>719950381
You're wrong. The 2 belongs in the denominator with the (1+2). Read a couple posts above. It's about how you group the terms with parentheses
>>
6/2(1+2)
6/2(3)
3(3)
9

>>719950573
clarify me then.
step by step.

>>719949936

No, it's really not. Type it into a computer program the way it is written in the OP, and it will evaluate it as 9.

Multiplication and division have the same precedence level and are evaluated from left to right.

If the writer of it intended you to read it with parentheses like you added, they would have written it with them. The answer to this problem is objectively 9.

6/2(1+2)
=6/2(3)

6 divided by 2 multiplied by 3. You then complete them from left to right and get 9.

6/2(3)=6x1/2(3)

>>719936082
1
>>
>>
>>719940528
Nope. Multiplication and division have the same priority in order of operations, so they are done left to right. Addition and subtraction have the same order of priority, so they too are prioritized left to right. Pretty basic stuff, really. Just Google it.
