Answer 1

Resposta:

A) =0+10+15−8=

=10+15−8=

=25−8=

=17

B) =15−12+60−95=

=3+60−95=

=63−95=

=−32

C) =9+15−6=

=24−6=

=18

D)=−30+17=

=−13

E) =+(−18)+19=

=1

F) =+10−5−10=

=+5−10=

=−5

G) =−3+7+10−14=

=4+10−14=

=14−14=

=0

H) =−2+2+15−1+1=

=0+15−1+1=

=15−1+1=

=14+1=

=15

I) =−105−72=

=−177

J) -17 + 27 = 10

10 - 31 =

- 21
