7 9 5 9 24点怎么算

lz您好，5 7 9 9只用加减乘除是算不出24点的，如果用非常规方法的话，那么
【（9 + 7）/ （9 - 5）】！= 24

1: (7 + 5 - 9) × 8
2: ((7 + 5) - 9) × 8
3: (7 + (5 - 9)) × 8
4: (7 - 9 + 5) × 8
5: ((7 - 9) + 5) × 8
6: (7 - (9 - 5)) × 8
7: 8 × (7 + 5 - 9)
8: 8 × ((7 + 5) - 9)
9: 8 × (7 + (5 - 9))
10: 8 × (7 - 9 + 5)
11: 8 × ((7 - 9) + 5)
12: 8 × (7 - (9 - 5))
13: 8 × (5 + 7 - 9)
14: 8 × ((5 + 7) - 9)
15: 8 × (5 + (7 - 9))
16: 8 × 5 -(7 + 9)
17: (8 × 5) - (7 + 9)
18: 8 × 5 - 7 - 9
19: (8 × 5) - 7 - 9
20: (8 × 5 - 7) - 9

22: 8 × (5 - 9 + 7)
23: 8 × ((5 - 9) + 7)
24: 8 × 5 -(9 + 7)
