Answer 3

To find the solution to the given expression, let's break it down step by step:

-9 + 15 + 10 - 12 - 10 - 7 + 9 + 5 - 15 + 20 - 12 - 8 - 13 + 6 + 16 - 20 + 6 - 8 - 13 + 4

Step 1: Combine the positive and negative numbers separately.

Positive numbers: 15 + 10 + 9 + 5 + 20 + 6 + 16 + 6 + 4 = 91 Negative numbers: 9 + 12 + 10 + 7 + 15 + 12 + 8 + 13 + 20 + 8 + 13 = 128

Step 2: Subtract the sum of negative numbers from the sum of positive numbers.

91 - 128 = -37

Therefore, the solution to the given expression is -37.
