Answer 1

Resposta:

Olá bom dia!

a=- 82

b= + 65

c= +100

d= -91

a) -82 + (+65) = -14

b) +100 + (-91) = +9

c) (-82) + (+65) + (+100) = -82 + 165 = +83

d) (+65) + (+100) + (-91) = 165 - (+91) = 165 - 91 = +74

Answer 2

Basta substituir

a) -82 + 65

-(82-65)

-17

b) 100 + (-91)

100 - 91

9

c) -82 + 65 + 100

-17 + 100

+(100-17)

83

d) 65 + 100 + (-91)

65 + 100 - 91

165 - 91

74
