b) 5 - [(2 + 9) - ( -4 - 2)] =
c) -18 + {[(-3 + 4) - (-5 - 7)] + [(-2 + 6) + (2 + 4)]} =
d) 25 – {[-6 + (5 + 10)] – [(10-5)+8]} =

Answer 1

Explicación paso a paso:

a)

$4 + (7 - ( - 5)) = 4 + 12 = 16$

b)

$5 - (11 - ( - 6)) = 5 - 17 = - 12$

c)

$- 18+ ((1 + 12) + (4 + 6)) = \\ - 18 + 13 + 10 = 5$

d)

$25 - (9 - 13) = 25 - ( - 4) = 29$
