Explicación paso a paso:
A = [2 - (-4-(-3 - 5 - (-2) - 11)] + 7
A = [2 - (-4-(-8 - (-2) - 11)] + 7
A = [2 - (-4-(-8+2- 11)] + 7
A = [2 - (-4-(-17) - 11)] + 7
A = [2 - (-4+17- 11)] + 7
A = [2 - 2] + 7
A = [0] + 7
A = 7
B = 12 + [5+ (7 - (+2) - 4)] - 8
B = 12 + [5+ (7 - 2- 4)] - 8
B = 12 + [5+ 1] - 8
B = 12 + 6- 8
B = 10
resta A de B:
B-A
10-7
