Answer 1

Hola! :3

Resolvemos:

a) (+2)-(-3)=a

2+3=a

5=a

b) (-6)+(-4)=b

-6-4=b

-10=b

c) (-4)-(-5)=c

-4+5=c

1=c

d) (-8)+(+10)=d

-8+10=d

2=d

e) (+6)-(+2)=e

6-2=e

4=e

f) (-10)+(+15)=f

-10+15=f

5=f

g) (+8)-(-12)=g

8+12=g

20=g

h) (+20)+(-10)=h

20-10=h

10=h

i) (+9)-(+2)=i

9-2=i

7=i

j) (-0.7)+(+0.2)=j

-0.7+0.2=j

-0.5=j

k) (-3.3)-(-2.4)=k

-3.3+2.4=k

-0.9=k

l) (+0.8)+(-0.3)=l

0.8-0.3=l

0.5=l

m) (+5.7)-(+4.2)=m

5.7-4.2=m

1.5=m

n) (-0.06)+(-0.001)=n

-0.06-0.001=n

-0.061=n

Espero haberte ayudado :D

Answer 2

Respuesta:

(+2)-(-3)=5

(-6)+(-4)=-10

(-4)-(-5)= 1

(-8)+(+10)= 2

(+6)-(+2)=4

(-10)+(15)=5

(+8)-(-12)=20

(+20)+(-10)=10

(+9)-(+2)=7

(-0.7)+(+0.2)= -0.5

(-3.3)-(-2.4)= -0.9

(+0.8)+(-0.3)=0.5

(+5.7)-(+4.2)=1.5

(-0.06)+(-0.001)=-0.061
