Answer: Step 1: Simplify the expression inside the parentheses. Since we have a negative sign before the second 8 inside the parentheses, we can change the sign of -8 to its opposite, which is positive 8. So, -8 - (-8) becomes -8 + 8. Step 2: Combine like terms. Since -8 and +8 have opposite signs, when we add them together, they cancel each other out. So, -8 + 8 equals 0. Therefore, the answer to -8 - (-8) is 0.
