c. -8 + [-(13 + (-5)) – 4 + 16] – 15
d. [9 + (-4)] - [-32 + (-5 + 4)] + 6

Answer 1

Explicación paso a paso:

$a) \: - 8 - ( - 15) + 16 = - 8 + 15 + 16 = 23 \\ b) \: - 17 + ( - 21) - ( - 19) - ( + 10) = - 17 - 21 + 19 - 10 = - 38 + 9 = - 29 \\ c) \: - 8 + ( - (13 + ( - 5)) - 4 + 16) - 15 \\ - 8 + ( - (8) + 12) - 15 \\ - 8 + 4 - 15 = - 19$

$(9 + ( - 4)) - ( - 32 + ( - 5 + 4)) + 6 \\ (5) - ( - 32 + ( - 1)) + 6 \\ 5 - ( - 32 - 1) + 6 \\ 5 - ( - 33) + 6 = 5 + 33 + 6 = 38 + 6 = 44$
