用2,8,9,8算24点

2, 7, 8, 9的24点答案: 1: (2 × (7 + 9)) - 8 2: 2 × (7 + 9) - 8 3: (2 × (9 + 7)) - 8 4: 2 × (9 + 7) - 8 5: (7 + 9) × 2 - 8 6: ((7 + 9) × 2) - 8 7: (9 + 7) × 2 - 8 8: ((9 + 7) × 2) - 8

1: (7 + 9) × 2 - 8 2: ((7 + 9) × 2) - 8 3: (9 + 7) × 2 - 8 4: ((9 + 7) × 2) - 8 5: (2 × (7 + 9)) - 8 6: 2 × (7 + 9) - 8 7: (2 × (9 + 7)) - 8 8: 2 × (9 + 7) - 8

(2*(7+9))-8 (2*(9+7))-8 ((7+9)*2)-8 ((9+7)*2)-8

((9-3)*8)/2 (9-3)*(8/2) (9-3)/(2/8) ((9-3)/2)*8 (9-(3*2))*8 (9-(2*3))*8 8*((9-3)/2) (8*(9-3))/2 8*(9-(3*2)) 8*(9-(2*3)) 8/(2/(9-3)) (8/2)*(9-3)

你好 这样可以得到:[2×(9+7)]-8

10减9加2乘8

2*8-1+9=24; 2*(9-1)+8=24; 8/(1+2)*9=24; 8-(1-9)*2=24;

1: 8 × (9 ÷ (10 - 7)) 2: 8 × 9 ÷(10 - 7) 3: (8 × 9) ÷ (10 - 7) 4: (8 ÷ (10 - 7)) × 9 5: 8 ÷ (10 - 7) × 9 6: 8 ÷ ((10 - 7) ÷ 9) 7: 9 × (8 ÷ (10 - 7)) 8: 9 × 8 ÷(10 - 7) 9: (9 × 8) ÷ (10 - 7) 10: (9 ÷ (10 - 7)) × 8 11: 9 ÷ (10 - ...

(2*9)-(2-8) ((2*9)-2)+8 ((2*9)+8)-2 (2*9)+(8-2) (2*9)-(2-8) ((2*9)-2)+8 ((2*9)+8)-2 (2*9)+(8-2) 8-(2-(2*9)) (8-2)+(2*9) 8-(2-(9*2)) (8-2)+(9*2) 8+((2*9)-2) (8+(2*9))-2 8-(2-(2*9)) (8-2)+(2*9) 8-(2-(9*2)) (8-2)+(9*2) 8+((2*9)-2)...

1. [7+﹙10+9﹚]-2 2. [10+﹙7+9﹚]-2 3. [﹙7+9﹚-2]+10
