To solve this you need to use PEMDAS (Parentheses, Exponent, Multiplication, Division, Addition, Subtraction).

PEMDAS is the order in which you need to do the problem.  First, do the work within the parentheses.  Then, do as the exponent require.  After that, multiply  as stated.  After all of this, you add in the end.
