Answer 1

Explicación paso a paso:

a) 5+(-6)+12+(-5) = (-6)+12 = 6

b) (-15)+23+(-8)+(-4) = -15+23+(-8)+(-4) = -15+23-8+(-4) = -15+23-8-4 = -4

c) (-1)+3+(-4)-(-13) = -1+3+(-4)-(-13) = 1+3-4-(-13) = -1+3-4+13 = 11

d) [(-13-14)-(-9-12)]+(-6) = ((-27)-(-9-12))+(-6) = ((-27)-(-21))+(-6) = ((-27)-(-21))-6 = (-27-(-21))-6 = (-27+21)-6 = (-6)-6 = -6-6 = -12

e) [(19-20)+(14-15)]-[(-7-13)+12] = ((-1)+(14-15))-((-7-13)+12)=((-1)+(-1))-((-7-13)+12) = ((-1)+(-1))-((-20)+12)=(-1+(-1))-((-20)+12)=(-1-1)-((-20)+12)= (-1-1)-(-20+12)=(-2)-(20+12) =(-2)-(-8)= -2+8)=6
