Lots of people have differing opinions.

I understand how it works but it just doesn't look right to me to divide then multiply because it goes against PEMDAS.

The parenthesis are done first (1+2) which equals 3.
Then, since there are no exponents you would move on to 6/2. Though in the acronym PEMDAS multiplication comes first, in the equation division comes first, and in any form of math when dealing only with division and multiplication you do the problem from left to right. Thus you are left with 6/2 (which is 3) times 3, which gives you an answer of 9.

multiplication and division have the same priority, so when all that is left is * and /, you go left to right. 9 is the correct answer.

I've heard of the dumbing-down of American education, but dear God, what are they teaching in schools these days? Order of operations should be the first thing on the plate. There is no answer but 9. Now, understanding that 9 is the answer, figure out how that comes about and reject any other logic. And never use that logic again--for this problem or any other....

Guys, I got the answer lol
The problem is poorly written! It's the main reason why there's so much ambiguity present and different interpretations have arisen.

It's 9, and I can't believe people don't understand order of operation. How do you debate it? It's a right and wrong question.
You also go left to right, if that helps.
Oh, and when there is no operation to sort out in between the parenthesis, you can treat is as multiplication.edit on 12-6-2012 by satron because: (no reason given)

I will go with 1, and you can blame the Canadian public education system on this one! They taught us BEDMAS , or Brackets Exponents Division Multiplication and Subtraction. So, I don't know, maybe I should have gone to private schools?

now this is where I guess I break the rule, cause I change it to:
3 (3)
meaning I do the division of the number outside the brackets before multiplying it against the sum inside the brackets, which technically breaks the rule.
