Write an expression for the sequence of operations described below.
add 3 and m, then subtract 7 from the result
Do not simplify any part of the expression.


  1. The answer is (3 + m) – 7
    7 is outside of the brackets because the problem states to subtract 7 after you add 3 and m, so to go according to PEMDAS we have to place 3 and m inside the brackets to tell us to do the addition first.
