My public school education on pemdas is that for multiplication/division and addition/subtraction, you do them on order from left to right. Doing it that way gets me 16, which I believe to be right, but I'm also very bad at math. The way you had explained is also technically correct, if you do the multiplication out of order. Now that I think about it, you could solve for the parentheses by multiplying 2+2 by two, giving you 8/8 quicker and still yielding 1. I'm now having more doubts about my math capabilities, both are right, but I know that's wrong, I just don't know why

No, that's the correct way to do it, as per The Distributive Law.

both are right

No, only 1 is right. If you get 16 then you did division before finishing solving brackets.
