Answer 1

Explicación paso a paso:

9+6=15

-7+(-3)=-10

-5-(-5)=-5+5=0

-(-2)-(-8)=+2+8=10

5+6=11

10+(-12)=-2

-(-6)=6

3-11=-8

-(-5)+(-14)=+5-14=-9

Answer 2

Respuesta:

Explicación paso a paso:

a) + ( + 9 ) – (+ 6 ) =+9-6=3

b) – ( + 7 ) + ( - 3 ) = -7-3=-10

c) + ( - 5 ) – ( - 5 ) = -5+5=0

d) – ( - 2 ) – ( - 8 ) = +2+8=10

e) + ( -4 +9 ) – ( - 6 ) = +(+5)+6=+5+6=11

f) – ( - 10 ) + ( + 3 – 15 ) = +10+(-12)=+10-12=-2

g) – (-3+11-8+6) = -(+6)=-6

h) + (-1+4) – (+17-6) = +(+3)-(+11)=+3-11=-8

i) – (-8+3) + (-5-9) =-(-5)+(-14)=+5-14=-9
