Question

a) 30 + [−16 − (−7 + 10)]
b) −10 − [11 + (−10 − 6)+ 1]
c) 18 – (14 + 15) – [13 – (16 – 21)]
d) −(−22)− [29 +(27 − 23− 26)− 28]
e) 9 −(−10) − [−21 − (−13− 13 + 25)]− (−18)
f) 11 + [−17 − (−22 + 16)+ (−29)] − (−46+ 54)
alguem me diz as resposta

Answer 1

Resposta:

a) 30 + [-16-3] = 30 - 19 = 11

b) -10 - [11 -15] = -10 + 4 = -6

c) 18 - 29 - [13 + 5] = -11 - 18 = -29

d) 22 - [29 - 22 - 28] = 22 - 21 = 1

e) 19 - [-21 + 1] + 18 = 19 + 20 + 18 = 57
