c) (+9) – [(+3) – (3 – 12) – (+8)]
d) [(+6) – (-8)] - [(-4) – (-10)]
e) [(2 – 8) + (5 – 7)] - [(-9 + 6) – (-5 + 7)]

Answer 1

Respuesta:

$a) \left(5-7\right)-\left[\left(-3\right)+\left(-6\right)\right] = 7$

$b) \left(-8\right)+\left[\left(7\right)-\left(-4\right)+\left(-5\right)\right] = -2$

$c) \left(9\right)-\left[\left(3\right)-\left(3-12\right)-\left(8\right)\right] = 5$

$d) \left[\left(6\right)-\left(-8\right)\right]-\left[\left(-4\right)-\left(-10\right)\right] = 8$

$e) \left[\left(2-8\right)+\left(5-7\right)\right]-\left[\left(-9+6\right)-\left(-5+7\right)\right] = -3$
