Answer 2

Oi.....

a) -4+(-7) =-4 -7 = - 11

b) 15-(-3)+(+1) = 15+3+1 = 19

c) -8+(-4)-(+2)=-8-4-2=-14

d) -5-(+2)-(-11)+(+4)=-5-2+11+4=-7+15=+8

e) 4 -(+2)+(-2)+(+8)=4-2-2+8=12-4=+8

f) 6-(-12)+(-7)+(-12)=6+12-7-12=+18-19=-1

g) -2+(-3)+(+7)-(-1)=-2-3+7+1=-5+8=+3

h) 9-(+4)-(-3)+(-5)=9-4+3-5=+12-9=+3

i) -11+(+2)+(-4)-(+7)=-11+2-4-7=-22+2=-20

j) -(-4)-(+3)+(-1)+(+6) =+4-3-1+6=+10-4=+6

k) 13+(-3)-(+4)-(-5)=13-3-4+5=+18-7=+11

l) (-8)-(+9)+(+2)-(-10) = -8-9+2+10=-17+12=-5

Espero ter ajudado.
