b) 1 kg - (27 kg + 35 kg) = 18 kg
(80 kg - 57 kg) + 1 kg = 72 kg
1 kg - (100 kg - 85 kg) = 59 kg
kg + (93 kg - 76 kg) = 81 kg
1 kg - (29 kg + 8 kg) = 19 kg
92 kg - kg - 9 kg) = 68 kg​

Answer 1

1-(27+35) = -61 != 18kg

(80-57)+1 = 24 != 72

1 - (100-85) = -14 != 59

1 + (93-76) = 18 != 81

1 - (29+8) = -36 != 19

92 - 1 - 9 = 82 != 68
