B)-3+0+(-7)-(-7)+(-1)

c)(-12)+(+17)-(-13)-(+17)-(-12)

D)(+14)+(-7)+(+6)-(-7)+(-5)-(+6)
resolva as somas algébricas (adições algébricas) por favor

Answer 1

a )-8+13=5-(-5)=5+5=10-12=-2-10=-12
b)-3+(-7)=-3-7=-10-(-7)=-10+7=-3+(-1)=-3-1=-4
c) (-12)+17=5-(-13)=5+13=18-(+17)=18-17=1-(-12)=1+12=13
d) 14+(-7)=14-7=7+6=13-(-7)=13+7=20+(-5)=20-5=15-(+6)=15-6=9

Answer 2

A)(-8)+(+13)-(-5)-12-10 = -8+13+5-12-10 = +5+5-22 = - 12

B)-3+0+(-7)-(-7)+(-1) = -3+0-7+7-1 = -3-1 = - 4

c)(-12)+(+17)-(-13)-(+17)-(-12) = -12+17+13-17+12 = + 13

D) (+14)+(-7)+(+6)-(-7)+(-5)-(+6) =  +14-7+6+7-5-6 = + 14-5 = + 9
