-1

#### Work Step by Step

According to the last step of order of operations, we must evaluate addition and subtraction from left to right.
First, we only consider $5-(-2)$. Change the minus sign to a plus sign and insert the opposite of the second number in place of the second number.
$5-(-2)=5+(2)=5+2=7$
Next, we can subtract 8 from 7.
$7-8=-1$
