Answer 3

To solve the expression -7 + (-8) - (-9) - 9 + 8 - (-4) - 3 + (-4), we can simplify it step by step:

1. Start with the first two terms: -7 + (-8) = -15.
2. Next, subtract the third term: -15 - (-9) = -15 + 9 = -6.
3. Subtract the fourth term: -6 - 9 = -15.
4. Add the fifth term: -15 + 8 = -7.
5. Add the sixth term: -7 - (-4) = -7 + 4 = -3.
6. Subtract the seventh term: -3 - 3 = -6.
7. Finally, subtract the eighth term: -6 + (-4) = -6 - 4 = -10.

Therefore, -7 + (-8) - (-9) - 9 + 8 - (-4) - 3 + (-4) equals -10.
