Answer 1

Resposta:

Explicação passo-a-passo:

a) + 10 + 2 = 12

b) + 5 + 18 = 23

c) + 12 + 34 = 46  

d) ( + 10 ) + ( – 13 ) =  -3

e) ( + 40 ) + ( – 17 ) = 23

f) ( + 12 ) - ( + 21 ) = -9

g) ( + 23 ) - ( + 21)= 2

h) ( + 3 ) + ( – 2 ) + ( – 5 )= -4

i) ( – 2 ) – ( + 1 ) – ( + 5 ) = -8

j) ( + 4 ) + ( – 2 ) – ( + 3 ) = - 1

Answer 2

Resposta:

a) + 10 + 2 = 12

b) + 5 + 18 = 23

c) + 12 + 34 = 46

d) ( + 10 ) + ( – 13 ) = -3

e) ( + 40 ) + ( – 17 ) = 23

f) ( + 12 ) - ( + 21 ) = -9

g) ( + 23 ) - ( + 21)= 2

h) ( + 3 ) + ( – 2 ) + ( – 5 )= -4

i) ( – 2 ) – ( + 1 ) – ( + 5 ) = -8

j) ( + 4 ) + ( – 2 ) – ( + 3 ) = -1
