1.- [(5-8)+3] - [4+(8-15)] 4.- [ ( 7+8-4)+ (-13)] + [(9-4)-(6+5)]

[(-3)+3] - [4+(-7) ] [(15-4) + (-13)] + [(5) - (11)]

[ 0] - [ -3] = 3 [ (11) - ( 13)]

2.- [(-2) + (-4+5)] + [(5+4) - ( -2+8)] [-2] - [-6] = 4

[ (-2) + (1)] + [ (9) - (6)]

[ -1] + [ 3]= 2


3.- [ 3+4 - (-7)] - [(5+4) - (-5)]

[7+ (7)] - [ 9+5]

[ (14)] - [(13)] = 1
