Explanation:

Think about like this if you get hurt in PE call an MD ASap

PE = a gym class so do Parenthesis and Exponents first.

MD = a medical doctor. This is one person so do Multiplication and Division at the same time. working from left to right.

AS(ap) = As Soon as possible. This is one time so do Addition and Subtraction at the same time working from left to right

Do the parenthesis first.

# 3 ( 7-2) - 8 = 3 (5) -8 #

Do the multiplication next

# 3(5) -8 = 15 -8#

Now do the subtraction

# 15-8 = 7 #
