Answer

$$5$$

Work Step by Step

To simplify this expression, we follow the order of operations. We simplify what is in parentheses first: $$-5 - (-8) - (-2)$$ Because we only have subtraction signs, we can go in order from left to right: We have to subtract a $-8$, which means we add $8$: $$-5 + 8 - (-2)$$ Add $8$ to $-5$: $$3 - (-2)$$ We are subtracting a $-2$, which means we add a $2$: $$3 + 2 = 5$$
