. Calcula el valor de “B – A”, si:
A = 2 – [– 4 – (–3 – 5 – (–2) – 11)] + 7.
B = 12 + [ 5 + (7 – (+2) – 4)] – 8.

a. 14 b. –13 c. –11 d. –15

Answer 1

Respuesta:

A = 2 – [– 4 – (–3 – 5 – (–2) – 11)] + 7

A = 2 – [– 4 – (–3 – 5 +2 – 11)] + 7

A = 2 – [– 4 – (-17)] + 7

A = 2 – [– 4 +17] + 7

A = 2 – [13] + 7

A = 2 – 13 + 7

A = -4

B = 12 + [ 5 + (7 – (+2) – 4)] – 8

B = 12 + [ 5 + (7 – 2 – 4)] – 8

B = 12 + [ 5 + 1] – 8

B = 12 + 6 – 8

B = 10

B-A

10 - (-4)

10 + 4

14
