I was taught PEMDAS. Parenthesis. Exponents. Multiplication. Division. Addition. Subtract. 2+2 is in the parenthesis, so that'd be 4. You times the other 2 with that now 4 which is 8. Then you divide 8 by 8 which gives you 1. That's if it's followed by PEMDAS.

The "or" parts are important because they tell you that multiplication and division are in the same category. So you are right that we need to do the (2+2) part first. But then we need to divide before multiplying since division and multiplication are the same in Order of Operations. It goes from left to right.
8/2(2+2) = 8/2(4) = 4(4) = 16
I used to be really confused by all this too and thought there were different answers but then they showed me the or parts and it made so much more sense.
