Answer 2

To simplify the expression and remove the parentheses, follow these steps:

1. Start with the original expression: 4 - (-8) + (-7) + (-4) + 7

2. Remember that a negative number within parentheses can be simplified by changing the sign of all the numbers inside the parentheses. For example, (-x) = -1 * x.

3. So, rewrite the expression by removing the parentheses: 4 + 8 + (-7) + (-4) + 7

4. Now, combine the like terms (numbers with the same sign): 4 + 8 = 12 -7 + (-4) = -11

5. The final expression is: 12 - 11 + 7

6. Continue combining like terms: 12 - 11 = 1 1 + 7 = 8

So, the simplified expression is 8.
