a) 1
b) 39
c) 16
d) -6
Explicación paso a paso:
a) 15 - (8 -5 + 9 +2) = 15 - (3 + 9 + 2) = 15 - (12 + 2) = 15 - 14 = 1
b) 25 + 40 : 2 - [5 - (8 - 9)] = 25 + 40 : 2 - [5 - (-1)] = 25 + 40 : 2 - 6 = 25 + 20 - 6 = 45 - 6 = 39
C) 2 x (5 + 3) - [4 - (12 - 8)] = 2 x (5+3) - ( 4 - 4) = 2 x 8 - 0 = 16 - 0 = 16
d) 5 + 3 - 4 - [7 - (2-5)] = 5 + 3 - 4 - (7 - (-3) = 5 + 3 - 4 - 10 = 8 - 4 - 10 = 4 - 10 = -6
