Normally, when you apply the PEMDAS (Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction) rule, you start with the operation inside the parenthesis. However, because it only involves one operation, which is addition, the order does not matter because of the Commutative Property of Addition.
