Answer 2

Explicación paso a paso:

6 + [5 + (7 + 2)] = 6 + [5 + 9] = 6 + 14 = 20

8 + [4 – (3 + 5)] = 8 + [4 - 8] = 8 + (-4) = 8 - 4 = 4

10 – [6 + (2 + 7)] = 10 - [6 + 9] = 10 - 14 = -4

15 – [2 – (6 – 10)] = 15 - [2 - (-4)] = 15 - [2 + 4] = 15 - 6 = 9

15 – [10 – (8 + 4)] = 15 - [10 - 12] = 15 - (-2) = 15 + 2 = 17

12 – [7 – (2 – 10)] = 12 - [7 - (-8)] = 12 - [7 + 8] = 12 - 15 = -3
