24点算法

Question

3，4，-6，10
3，-5，7，-13
可以使用括号，第一题要求写出3组算式，第二题一组算式。

Answer 1

您好！

10-(-6)×3-4=24

3×(10+4+(-6))=24

(10-4)×3-(-6)=24

[（-13）×（-5）+7]÷3=24

Answer 2

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

[(-5)*(-13)+7]/3 = 24
[7-（-13）*5]/3 =24
