Solution:

To simplify the expression 7 - (-4) + 3(-6), follow the order of operations, which is PEMDAS (Parentheses, Exponents, Multiplication/Division, Addition/Subtraction):

1. Start with the operation inside the parentheses:

-(-4) = 4

2. Next, perform multiplication:

3 * (-6) = -18

3. Now, substitute the results back into the expression:

7 + 4 - 18

4. Finally, perform addition and subtraction from left to right:

7 + 4 = 11

11 - 18 = -7

The simplified expression is -7.
