1. The problem is to evaluate the expression: $-7 - (11)$ using the KFC (Keep, Flip, Change) method. 2. KFC stands for: - Keep the first number as it is. - Flip the subtraction sign to addition. - Change the sign of the number inside the parentheses. 3. Applying KFC to $-7 - (11)$: - Keep: $-7$ - Flip: $-$ becomes $+$ - Change: $(11)$ becomes $-11$ So, the expression becomes: $$-7 + (-11)$$ 4. Now, add the two numbers: $$-7 + (-11) = -(7 + 11) = -18$$ 5. Therefore, the final answer is: $$\boxed{-18}$$
