Question

calcule o valor das expressões A) (12+2×5)-8 = B) 25-(15+6×3 = C) 25+(7+(8-4÷2) = D) 60 - (8+(10-2)÷2 = E) 80-(22 + (5×2-1)+6) =​

Answer 1

Resposta:

A) (12+2×5)-8 => (12+10)-8 = 14

B) 25-(15+6×3) => 25-(15 + 18) = -8

C) 25+(7+(8-4÷2) =>  25+(7+(8-2)) = 25+13 = 38

D) 60-(8+(10-2)÷2 => 60-(8+8:2) = 60-(8+4) = 48

E) 80-(22 + (5×2-1)+6) => 80-(22+(10-1)+6) = 80-(37) = 43
