What the forget, i was just talking to my friend about this.
There are 2 ways to solve this, and the problem arises in that I'm not sure if the parenthesis is canceled after you multiple. Let's lay this out:
6÷2 (1+2) = ?
6÷2 * 3 = ?
3 * 3 = 9
or
6÷2 (1+2) = ?
6÷2 (3) = ?
6÷6 = 1
I believe it's 9, but if you think the parenthesis should stay around the 3 PEMDAS tells you to multiple the 2 and (3). I think it's 9 because once you add 1 and 2 you're left with just 3. And then PEMDAS tells you to multiple and divide left to right.
