Answer 1

Resposta:

3 + 2 – 4 = 1

12 + 5 – 8 = 9

7 – 3 + 5 = 9

8 – 1 + 2 = 9

– 3 + 5 – 2 – 9 = -9

7 + 8 – 6 – 4 – 3 = 2

– 5 + 4 – 2 – 7 + 3 = -7

23 – 45 – 12 + 67 = 33

72 – 24 – 56 + 13 = 5

68 – 34 – 54 + 43 = 23

– 27 – 35 – 68 – 98 = -228

48 + 25 + 79 – 99 = 53

59 – 43 – 76 + 24 = -36

86 – 64 – 78 + 28 = -28

– 46 + 25 – 135 + 47 = -109

90 – 40 – 37 + 62 = 75

73 – 87 – 98 + 97 = -15

27 – 74 – 31 + 38 = 40

88 + 54 + 99 – 43 = 198

87 – 54 – 34 + 33 = 32

–20 + 30 + 20 – 30 = 0

–13 + 46 + 13 – 46 = 0

98 – 65 – 87 + 95 = 41

77 – 66 + 22 + 55 = 88
