Answer 1

Explicação passo-a-passo:

a) [35:5+ 3.12 -(54:9)1-7 =

[7 + 36 -(6)1-7 =

[43 - 6 - 7=

43 - 13=

30

b) 4.7 +3.8-27: 9 + 96 : 6 =

28 + 24 - 3 + 16 =

52 - 3 + 16 =

49 + 16 =

65

c) {[67 - (49:7) + (72:9)-2°1} + 45 =

{[67 - 7 + 8 - 2} + 45 =

{[60 + 6 } + 45 =

66 + 45 =

111

d) 125 - {32:2+ [75: 5 - (12:4) 1 =

125 - {16 + [15 - (3) 1 =

125 - {16 + 12

125 - 28

96
