#### Answer

-7

#### 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 $-12-(-3)$. Change the minus sign to a plus sign and insert the opposite of the second number in place of the second number.
$-12-(-3)=-12+(3)=-12+3=-9$
Next, we can add this to -2 by using the same process.
$-9-(-2)=-9+(2)=-9+2=-7$
