类似24点难题

24点游戏主要找24的因数.先看-6发现其他三个数难得-4.再看8发现得到3很容易:-6+7+2=3,所以得到:(-6+7+2)*8=24

(-6+2+7)*8=24

很好做 你是要直接的算式吗？
1: (2 - 6 + 7) × 8
2: ((2 - 6) + 7) × 8
3: (2 - (6 - 7)) × 8
4: (2 + 7 - 6) × 8
5: ((2 + 7) - 6) × 8
6: (2 + (7 - 6)) × 8
7: (2 × (7 + 8)) - 6
8: 2 × (7 + 8) - 6
9: (2 × (8 + 7)) - 6
10: 2 × (8 + 7) - 6
11: (7 - 6 + 2) × 8
12: ((7 - 6) + 2) × 8
13: (7 - (6 - 2)) × 8
14: (7 + 2 - 6) × 8
15: ((7 + 2) - 6) × 8
16: (7 + (2 - 6)) × 8
17: (7 + 8) × 2 - 6
18: ((7 + 8) × 2) - 6
19: 8 × (2 - 6 + 7)
20: 8 × ((2 - 6) + 7)
21: 8 × (2 - (6 - 7))
22: 8 × (2 + 7 - 6)
23: 8 × ((2 + 7) - 6)
24: 8 × (2 + (7 - 6))
25: 8 × (7 - 6 + 2)
26: 8 × ((7 - 6) + 2)
27: 8 × (7 - (6 - 2))
28: (8 + 7) × 2 - 6
29: ((8 + 7) × 2) - 6
