有一种“二十四点”的游戏，其游戏规则是这样的，任取四个1~13之间的正整数，将这四个数（每个数且只用一

Question

进行加减乘除运算，使其结果等于24，现有四个正整数：2、2、3、11，运用上述规则，写出算式！！！！！！！！！！！！！！！

Answer 1

1: 2 × (3 - 2 + 11)
2: 2 × ((3 - 2) + 11)
3: 2 × (3 - (2 - 11))
4: 2 × (3 + 11 - 2)
5: 2 × ((3 + 11) - 2)
6: 2 × (3 + (11 - 2))
7: 2 × (11 - 2 + 3)
8: 2 × ((11 - 2) + 3)
9: 2 × (11 - (2 - 3))
10: 2 × (11 + 3 - 2)
11: 2 × ((11 + 3) - 2)
12: 2 × (11 + (3 - 2))
13: (3 - 2 + 11) × 2
14: ((3 - 2) + 11) × 2
15: (3 - (2 - 11)) × 2
16: (3 + 11 - 2) × 2
17: ((3 + 11) - 2) × 2
18: (3 + (11 - 2)) × 2
19: (11 - 2 + 3) × 2
20: ((11 - 2) + 3) × 2
21: (11 - (2 - 3)) × 2
22: (11 + 3 - 2) × 2
23: ((11 + 3) - 2) × 2
24: (11 + (3 - 2)) × 2

Answer 2

3-2=1
11+1=12
12X2=24

Answer 3

[(3-2)+11]x2=24
