Answer 3

To simplify the given expression, perform the operations step by step:

1. Add the numbers within parentheses first: -15 + 11 - (-34) + 49 - 24 - 55 - (-4) - 77 + (-81)

2. Now, perform the operations involving negatives: -15 + 11 + 34 + 49 - 24 - 55 + 4 - 77 - 81

3. Finally, add all the numbers together: = -15 + 11 + 34 + 49 - 24 - 55 + 4 - 77 - 81 = -74

So, the simplified value of the expression is -74.
