## Elementary Algebra

We first follow the instructions to plug in -13 for F. When we are simplifying a fraction, we simplify the numbers in the numerator and the denominator before dividing. According to order of operations, we first consider everything inside of the parenthesis. Because multiplication is before subtraction and addition in order of operations, once within the parenthesis, we first multiply, and then we add and subtract. $5(-13-32) \div 9 = 5(-45) \div 9 = -225 \div 9 =-25$
