Question

1) Resolva as expressões numéricas abaixo:
a) 80 + { 5 + [ ( 8 + 12 ) + ( 13 + 12 )] + 10 } =
b) 38 – { ( 51 – 15 ) + [ 5 + (3 – 1 ) ] – 10 } =
c) {[ ( 8 x 4 + 3 ) ÷ 7 + ( 3 + 15 ÷ 5 ) x 3 ] x 2 – ( 19 – 7 ) ÷ 6 } x 2 + 12 =
d)

Answer 1

A)80 + { 5 + [ 20 + 25 ] + 10 } =
80 + { 5 + 45 + 10 } =
80 + 60 = 140
B)38 - { 36 + [ 5 + 2 ] - 10 } =
38 - { 36 + 7 - 10 } =
38 - 33 = 5
C){[ 35 ÷ 7 + 6 × 3 ] × 2 - 12 ÷ 6 } × 2 + 12 =
{ 23 × 2 - 12 ÷ 6 } × 2 + 12 =
44 × 2 + 12 = 100
D)
