现有4个有理数3.-5.11.7按24点游戏规则些一个算术

((7*11)+-5)/3
(7-3)*(11+-5)
(7-3)*(-5+11)
((11*7)+-5)/3
(11+-5)*(7-3)
(-5+(7*11))/3
(-5+11)*(7-3)
(-5+(11*7))/3

1:[(-5)-(-11)×7]÷3=24
2: (3 - 7) × (5 - 11)
3: (5 - 11) × (3 - 7)
4: (11 - 5) × (7 - 3)
5: (11 × 7 - 5) ÷ 3
6: ((11 × 7) - 5) ÷ 3
7: (7 - 3) × (11 - 5)
8: (7 × 11 - 5) ÷ 3
9: (7 × 11) - 5) ÷ 3
10:(-3)×[(-5)-(-11)]=24
11:（11×7-5）÷3
12:((7*11)+-5)/3
13:(7-3)*(11+-5)
14:(7-3)*(-5+11)
15:((11*7)+-5)/3
16:(11+-5)*(7-3)
17:(-5+(7*11))/3
18:(-5+11)*(7-3)
19:(-5+(11*7))/3

（11×7-5）÷3

(11-5)*(7-3)
