( +8 ) + ( –13 ) + (+ 28 ) = B. (–17 ) + ( –6 ) + ( –10 ) = C. ( –3 ) - ( –12 ) + (+ 20 ) =
D. (
–11 ) + ( +18 ) + ( –7 ) = E. ( –37 ) + ( –7 ) + ( –11 ) + ( +18 ) = F. ( –12 ) – ( +63 )

Answer 1

Respuesta:

A. ( +8 ) + ( –13 ) + (+ 28 ) = 8 - 13 + 28 = 23

B. (–17 ) + ( –6 ) + ( –10 ) = - 17 - 6 - 10 = - 33

C. ( –3 ) - ( –12 ) + (+ 20 ) = - 3 - 12 + 20 = 5

D. ( –11 ) + ( +18 ) + ( –7 ) = - 11 + 18 - 7 = 0

E. ( –37 ) + ( –7 ) + ( –11 ) + ( +18 ) = - 37 - 7 - 11 + 18 = - 37

F. ( –12 ) – ( +63 )= - 12 - 63 = - 75
