Answer 1

Respuesta:

4)

a) 4+3+8 = 15

b) (-5)+(-2)+(-6) = -13

c) (-11)+8+(-9)+10 = (-20)+18 = -2

d) (-4)-(-3)-(-8) = -4+3+8 = 7

e) 8-11-2 = 8-13 = -5

f) (-13)-9-(-7)-12 = (-13)-9+7-12 = -34+7 = -27

5)

a) (-5)+(-2)-(-1)+4-6 = -5-2+1+4-6 = -13+5 = -8

b) (-7)-2+8-(-4) = -7-2+8+4 = -9+12 = 3

c) -8+(-4)-(-2)+7-3+(+5)= -8-4+2+7-3+5 = -15+14 = -1

d) (-12)+(-7)-10+(+4)-(-9)= -12-7-10+4+9 = -29+13 = -16

e) (-10)-(-3)+(-18)+(+5)-2= -10+3-18+5-2 = -30+8 = -22

f) 12+(-18)-(-6)+(-7)-2 = 12-18+6-7-2 = 18-27 = -9

g) (-15)-(-15)+(-8)+11-2 = -15+15-8+11-2 = -25+26 = 1

h) 20-9+(-12)+(+7)-(-2)+10 = 20-9-12+7+2+10 = 39-21 = 18
