Answer 1

Resposta:

Explicação passo a passo:

A) (+8)+(+6)

= 8+6

=14

B) (-12)+(-6)

= -12-6

D) (-71)+(+134)=

= 134 - 71

= 63

E) (+36)+(+15)+(+4)=

= 36+15+4

= 51+4

= 55

F) (-22)+(-8)+(-15)=

= -22-8-15

= - 30 - 15

= - 45

G) (+8)-(+4)= 8-4

= 4

H) (+21)-(-5)= 21+5

=26

I) (+12)-(-3)= 12+3

=15

J) -(-2)-(-3)-(15)

= 2+3-15

= -10

K) -(+19)+(-8)-(+5)-(-17)=​

= -19-8-5+17

= - 27+12
