RESPOSTA COM OS CALCULOS PFVR

Answer 1

(-2)-(+1)-(+5) = (-2)-1+5 = (-3)+5 = 2

(+5)-(-3)-(-1) = 5+3+1= 9

(+4)+(-6)-(+7)-(-6)+(+7)=  4-6-7+6+7 = 4

(-3)-(-5)+(-6)+(+8)-(-4)=  (-3) +5 -6+8+4 = 8

+(-3+8)-(-3+8)+(5-6)=  (-3)+8+3-8+5-6 = (-1)

-(-3-1)-(-6+4-1)-6-(-3+2)=  3+1+6-4+1-6+3-2 = 2

18-(-5-2-3)+20-(-6+8)-(-1-8+3)=  18+5+2+3+20+6-8+1+8-3 = 54

-32-1-(-12+14+7)+(-5-6-9+3)-17=  -32-1+12-14-7-5-6-9+3-17 = (-76)
