D)
(+8)-(-4)-(+4) -(+10-(-5)-(-8)=

E)
-2+8-8+10-20+5-7

f)
9-7+11-20+12-23+5-5-12​

Answer 1

Respuesta:

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

+2-3+3-5-2= -5

(-2)+(-7)+(+3)+(-4)+(-11)=

-2-7+3-4-11= -21

(-7)-(-4)-(+4)-(+10)+(-2)-(-13)=

-7+4-4-10-3+13= -7

(+8)-(-4)-(+4) -(+10-(-5)-(-8)=

+8+4-4-10+6+8= 12

-2+8-8+10-20+5-7= -14

9-7+11-20+12-23+5-5-12= -30

espero te ayude ....

Answer 2

Respuesta:

(+2)+(−3)+(3)+(−5)+(−2)= -5

(−2)+(−7)+(3)+(−4)+(−11)= -21

(−7)−(−4)−(4)−(10)+(−2)−(−13)= -6

(8)−(−4)−(4)−(10−(−5)−(−8)= -15

−2+8−8+10−20+5−7= -14

9−7+11−20+12−23+5−5−12= -30
