#### 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.

$3 \left(7 - 2\right) - 8 = 3 \left(5\right) - 8$

Do the multiplication next

$3 \left(5\right) - 8 = 15 - 8$

Now do the subtraction

$15 - 8 = 7$
