Explicación paso a paso:
a) 5 – (9 – 3) = 5 – 9 + 3 = 8 - 9 = -1
a) 5 – (9 – 3) = 5 – (6) = 5 - 6 = -1
b) 7 + (2 – 8) = 7 + 2 - 8 = 9 - 8 = 1
b) 7 + (2 – 8) = 7 + (-6) = 7 - 6 = 1
c) 12 + (–3 + 10) = 12 - 3 + 10 = 22 - 3 = 19
c) 12 + (–3 + 10) = 12 + (7) = 12 + 7 = 19
d) 15 – (8 + 11) = 15 - 8 - 11 = 15 - 19 = -4
d) 15 – (8 + 11) = 15 - (19) = 15 - 19 = -4
e) +(9 – 10) – 2 = 9 - 10 - 2 = 9 - 12 = -3
e) +(9 – 10) – 2 = (-1) - 2 = -1 - 2 = -3
f) –(7 + 4) + 14 = - 7 - 4 + 14 = -11 + 14 = 3
f) –(7 + 4) + 14 = -(11) + 14 = -11 +14 = 3
g) (5 + 8) – (7 + 6) = 5 + 8 - 7 - 6 = 13 - 13 = 0
g) (5 + 8) – (7 + 6) = (13) - (13) = 13 - 13 = 0
h) (16 – 9) – (10 – 7) = 16 - 9 -10 + 7 = 23 - 19 = 4
h) (16 – 9) – (10 – 7) = (7) - (3) = 7 - 3 = 4
