Answer 1

a) 5
e) 1
b) -7
0) 4
c) 2
9) 0
d) 11
h) 10

Answer 2

Resposta:

a)5

e)1

b)-7

0)4

c)2

9)0

d)11

h)-10

Explicação:

a)( + 3) + ( + 2) = 3+2 = 5

e) (-6) + ( + 7) = -6+7 = 1

b) (-2) + (-5) = -2-5 = -7

0) (-8) + ( + 12) = -8+12 = 4

c) ( + 4) + (-2) = 4-2 = 2

9) (+11)+(-11) = 11-11 = 0

d) ( + 5) + ( + 6) = 5+6 = 11

h)(+5) + (-15) = 5-15 = -10
