Question

Questão 01) Resolva as expressões numéricas a seguir: a) 9 + (7 − 5) ÷ 2 − 10 ÷ 2 =
b) 11 + {20 − [3 − (10 − 8)] + 5} = c) [40 − (32 + 5)] ∙ {[(12 − 8) + 10] ÷ 7}

Answer 1

Resposta:

a) 5

b) 35

c) 6

Explicação passo a passo:

a) 9 + (7 − 5) ÷ 2 − 10 ÷ 2 =

9 + 2 : 2 - 5

9 + 1 - 5

10 - 5

5

b) 11 + {20 − [3 − (10 − 8)] + 5} =

11 + {20 - [3 - 2] + 5}

11 + {20 - 1 + 5}

11 + {19 + 5}

11 + 24

35

c) [40 − (32 + 5)] ∙ {[(12 − 8) + 10] ÷ 7} =

[40 - 37] . {[4 + 10] : 7}

3 . {14 : 7}

3 . 2
