Recall order of operations: PEMDAS, Parenthesis, Exponents, Multiplication, Division, Add, Subtract. Evaluate each, then start to plug the values back in before moving on.
These are in parenthesis, so start here:
(11-7)=A?
(5x3)=B?
Once you know those, plug them back into the original expression:
32+[A+B] ... Addition is "commutative" which simply means the order of when you add things doesn't matter. So, you ultimately have:
32+A+B=?
