Answer:
Because you must follow the order of operations.
Step-by-step explanation:
PEMDAS is the order of operations
P - Parenthesis
E - Exponents
M - Multiplication
D - Division
A - Addition
S - subtraction
You add the 6 + .5 first because they are inside the parenthesis. Then we do the multiplication.
