Answer 2

It looks like you've provided a series of mathematical expressions, and it seems you want me to solve them for you. Let's break down each expression:

1. -(7×8-20)+7-8 = -(56 - 20) + 7 - 8 = -(36) + 7 - 8 = -36 + 7 - 8 = -29 - 8 = -37

2. -(2×5+48)+23 = -(10 + 48) + 23 = -(58) + 23 = -58 + 23 = -35

3. +(-120-9×9)-81 = (-120 - 81) - (9×9) = (-201) - 81 - 81 = -201 - 81 = -282

4. -(-79-39+81)+81-39 = (79 + 39 - 81) + 81 - 39 = (117 - 81) + 81 - 39 = 36 + 81 - 39 = 117 - 39 = 78

So, the results of the expressions are as follows:

1. -37
2. -35
3. -282
4. 78
