Have you any examples of actual expressions / actual homework from this section of your math course?   The question you've posted can be answered, but I'd much rather answer it while looking at a real-life example (expression).

I believe this question is all about "order of operations," often abbreviated to "PEMDAS."
Are you familiar with that?
