Answer 1

1:(1 + 7) ÷ 2 × 6 2:((1 + 7) ÷ 2) × 6 3:(1 + 7) ÷ (2 ÷ 6) 4:(1 - 7) × (2 - 6) 5:(1 + 7) × 6 ÷ 2 6:((1 + 7) × 6) ÷ 2 7:(1 + 7) × (6 ÷ 2) 8:(2 - 6) × (1 - 7) 9:2 × (6 - 1 + 7) 10:2 × ((6 - 1) + 7) 11:2 × (6 - (1 - 7)) 12:2 × (6 + 7 - 1) 13:2 × ((6 + 7) - 1) 14:2 × (6 + (7 - 1)) 15:2 × (7 - 1 + 6) 16:2 × ((7 - 1) + 6) 17:2 × (7 - (1 - 6)) 18:2 × (7 + 6 - 1) 19:2 × ((7 + 6) - 1) 20:2 × (7 + (6 - 1)) 21:(6 - 1 + 7) × 2 22:((6 - 1) + 7) × 2 23:(6 - (1 - 7)) × 2 24:(6 × (1 + 7)) ÷ 2 25:6 × (1 + 7) ÷ 2 26:6 × ((1 + 7) ÷ 2) 27:6 ÷ 2 ×(1 + 7) 28:(6 ÷ 2) × (1 + 7) 29:6 ÷ (2 ÷ (1 + 7)) 30:(6 - 2) × (7 - 1) 31:6 ÷ 2 ×(7 + 1) 32:(6 ÷ 2) × (7 + 1) 33:6 ÷ (2 ÷ (7 + 1)) 34:(6 + 7 - 1) × 2 35:((6 + 7) - 1) × 2 36:(6 + (7 - 1)) × 2 37:(6 × (7 + 1)) ÷ 2 38:6 × (7 + 1) ÷ 2 39:6 × ((7 + 1) ÷ 2) 40:6 × (7 - (1 + 2)) 41:6 × (7 - 1 - 2) 42:6 × ((7 - 1) - 2) 43:6 × (7 - (2 + 1)) 44:6 × (7 - 2 - 1) 45:6 × ((7 - 2) - 1) 46:(7 + 1) ÷ 2 × 6 47:((7 + 1) ÷ 2) × 6 48:(7 + 1) ÷ (2 ÷ 6) 49:(7 - (1 + 2)) × 6 50:(7 - 1 - 2) × 6 51:((7 - 1) - 2) × 6 52:(7 + 1) × 6 ÷ 2 53:((7 + 1) × 6) ÷ 2 54:(7 + 1) × (6 ÷ 2) 55:(7 - 1 + 6) × 2 56:((7 - 1) + 6) × 2 57:(7 - (1 - 6)) × 2 58:(7 - 1) × (6 - 2) 59:(7 - (2 + 1)) × 6 60:(7 - 2 - 1) × 6 61:((7 - 2) - 1) × 6 62:(7 + 6 - 1) × 2 63:((7 + 6) - 1) × 2 64:(7 + (6 - 1)) × 2 ②水:(660-440)÷(5-3)=110 杯子:440-3×110=110
