Answer 1

Explicação passo-a-passo:

a) +1 - ( -1) + (+4) - ( +4)=

1 + 1 + 4 - 4=

2

b) ( 8 + 5 - 12) : ( - 1)=

( 13 - 12) : (-1)=

(+1) : (-1)=

- 1

c) - 2 . ( - 4) . ( - 8)=

( + 8) . (- 8)=

- 64

d) (-2).(-3).(-4) .(+5) .(-3) . (+2)=

( + 6) . (-4).(+5).( -3) .(+2)=

( - 24) .(+5) .(-3) .(+2)=

( - 120) . (-3) .(+2)=

( + 360).(+2)=
