Answer 1

Explicação passo-a-passo:

( 6 ) + ( + 3 )= 9

( +15) + ( + 15)= 30

( -7) + ( + 8)= 1

( - 14) + ( +10)= -4

( -6 ) + ( +12)= 6

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

( 8) + ( - 5)= 3

( + 20) + ( -15)= 5

(-25) + ( +20)= -5

(-8) + ( -4)= -12

(-5) + ( -5)= -10

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

( -20) + ( -10)= -30

( 30) + ( -20)= 10

(-20) + ( -15)= -35

(50) + ( -30)= 20

( 8) + ( +30)= 38

(-14) + ( -10)= -24

(+24) + ( -20)= 4

(-18) + ( + 14)= -4
