Answer
-9
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.
$-5-(-2)=-5+(2)=-5+2=-3$
Next, we can add this to -6.
$-3+(-6)=-9$
