Answer 1

Resposta:

a)(-2)+(-3)+(+2)

-2-3+2=-3

b)+3+(-3)+(-5)

+3-3-5=-5

c)(+1)+(+8)+(-2)

1+8-2=7

D)(+5)+(-8)+(-8)

5-8-8= -11

e)(-6)+(-2)+(+1)

-6-2+1=-7

f)(-8)+(+6)+(-2)

-8+6-2 = -4

g)(-7)+6+(-3)

-7+6-3=-4

H)6+(-6)+(-7)

6-6-7=-7

I)-6+(+9)+(-4)

-6+9-4=-1

j)(-4)+2+4+(+1)

-4+2+4+1=3
