Answer 1

Resposta:

A) 36

B) 95

C) 16

D) 0

Explicação passo-a-passo:

A) 34 - (15 - 3 . 2 ) + 11 =

34 - ( 15 - 6 ) + 11 =

34 - 9 + 11 =

25 + 11 = 36

B) 125 - 6 . (4 + 1) =

125 - 6 . 5 =

125 - 30 = 95

C) 15 + (17 - 8 - 5) - 3 =

15 + (9 - 5) - 3 =

15 + 4 - 3 =

19 - 3 = 16

D) 32 ÷ 8 - 1 . 4 =

4 - 4 = 0
