Answer 1

Resposta:

Explicação passo-a-passo:

A) 76 - 65 = 11

B) -34 + 42 = 8

C) -56 - 27 = -83

D) 68 + 35 = 103

E) (-11 + 35 ) = 24

F) +( -54 + 76 – 47 ) = - 25

G) ( - 68 + 83 – 54 ) = - 49

H) ( -35 + 46 ) + ( -32 + 17 ) = -4

I)  ( + 54 ) × ( - 35 ) = - 1890

J) ( - 36 ) × ( - 48 ) = 1728

K) ( + 48 ) × ( + 54 ) = 2592

L)  ( - 76 ) × ( - 72 ) = 5472
