给你一个计算24点的网站,你只要从0---9中任意取四个数字输入进去就行了.

(1+2)*(3+5)=24

(9-6)×8/1

要算210种可能?0-9任意取4个算24,有210种可能啊,每种都要算?呵呵,恐怖
都打不完
别的不说,0,1,2,3怎么可能算出?除非23+1+0,不然最大只有9啊

1...(2+1)*(3+5)
2...(1+3)*(2+4)
...........................
算了，还 有很多，懒的写
你应该加一句，不许加括号，不然的话有n多个.
不过不加括号好象也有n多个哦
比如：5*6-2-4,不写了,这什么题啊,我晕

(2+4)*(5-1)=24

谁能用0~9数字中的任意四个通过加减乘除算得24？
1+3+4×5=24

5*5-5\5=24

我已经汇总了使用1～13计算24的全解

-2+8*5+4=24
读: 负二减..

(9-6)×8/1=24
对吗?

(6/2)*(9+ -1)=24
(8-2)*(3+1)=24
