Even in that order I'm still confused From what I remember (bear in mind it's been at least 7 years since I did this stuff and in England the exams are "dumbed down" anyway) dealing brackets first means you should get rid of them, so you'd multiply the (2+1) with the 2 rather than leaving it as 6/2(3) and thus end up with 6/6 = 1.

Another possibility is that I may have remembered this all wrong. Apparently that's the case

To me both multiplication and division or addition and substraction are equal. So I will start from left to right in the equation:

6÷2（2+1）= 6/2 (3) = 3 (3) = 9!

Re: 6÷2（2+1）=？

It's 9

6/2=3
2+1=3

First you have to opperate the parenthesis, then you opperate from let to right. 3 x 3 = 9

Well I would definitely defriend someone if he started insulting me because of saying the correct answer

Well mathematics is a language with very fussy, standardized grammar, and the way the expression is written makes it equal to 9.

1 is neither a logically sound nor appropriate answer because the expression 6÷2(2+1) means "take 6, divide by two, multiply by 3." It does not mean "multiply 2 by 3 and divide 6 by that whole thing." There is one way of interpreting what is written here.

So basically we should dismiss what they taught us in school?

I'm not even surprised

No, this is what they taught you in school

You do what's inside the brackets first, i.e. change 2+1 to 3...then the expression is 6÷2 x 3.
