En resumen

2 + 4( - 3 + 1) = 2 + ( - 12 + 4) = 2 + ( - 8) = 2 - 8 = - 6 7 + 2 - (3 + 9) = 9 - (12) = 9 - 12 = - 3 5 - 10(2 + 1) - (4 + 6) = 5 - (20 + 10) - (4 + 6) = 5 - ( + 30) - ( + 10) = 5 - 30 - 10 = - 35.

2 + 4( - 3 + 1) = 2 + ( - 12 + 4) = 2 + ( - 8) = 2 - 8 = - 6

7 + 2 - (3 + 9) = 9 - (12) = 9 - 12 = - 3

5 - 10(2 + 1) - (4 + 6) = 5 - (20 + 10) - (4 + 6) = 5 - ( + 30) - ( + 10) = 5 - 30 - 10 = - 35.
