Question

Resolva as expressões abaixo:
a) [(9 + 3) x 4] : 3 + 5 =
b) 50 [(14 : 2 + 3)] + 5 =
c) 17 + {[26-(15 – 8) + (8 – 4) + 9} =
d) {18 + [6 x(16 – 4) – 8]} =​

Answer 1

a) [(9 + 3) x 4] : 3 + 5 = [12 × 4] : 3 + 5 = 48 : 3 + 5 = 21

b) 50 [(14 : 2 + 3)] + 5 = 50 . [10] + 5 = 505

c) 17 + {[26-(15 – 8) + (8 – 4) + 9} = 17 + {26 - 7 + 4 + 9}

= 17 + 32 = 49

d) {18 + [6 x(16 – 4) – 8]} = {18 + [6 × 12 - 8]}

= 18 + 64

= 82
