​

Answer 1

Resposta:

1)

a)(+27)+(+13)+(-28

27 + 13 -28

40 -28

12

b)(-50)+(-30)+(-12)

-50 -30 -12

-92

c)(+90)+(-75)+(-47)

90 -75 -47

90 - 122

-32

d)(-11)+(+20)+(+35)+(-27)

-11 +20 +35 -27

55 -38

17

e)(+32)+(-68)+(-22)+(+48)

32 -68 -22 +48

80 -90

-10

f)(+99)+(-100)+(-100)+(+98)+(-10)

99 -100 -100 +98 -10

197 -210

-13

g)(-73)+(-22)+(-45)+(-92)+(+250)

-73 -22 -45 -92 +250

-232 +250

18

2) a= -82, b= +65, c=+100 e d=-91

a)a+b

(-82) +(+65)

-82 +65

-17

b)c+d

(+100) +(-91)

100 -91

9

c)a+c

(-82) +(+100)

-82 +100

18

d)b+d

(+65) +(-91)

65 -91

-26

e)a+d

(-82) + (-91)

-82 -91

-173

f)a+b+c+d

​(-82) +(+65) +(+100) +(-91)

-82 +65 +100 -91

165 -173

-8
