由四个1~9的数字运算获得24的404个解,见我的一个收藏贴:
http://sh.focus.cn/msgview/10953/76588832.html
1,4,6,10: (4-1)*10-6=24,
2,2,7,10:
7,7,8,9:【在收藏贴中没有耶!除非考虑超出四则运算范围的运算模式。】
5,7,8,10: (10-8)(5+7)=24.
3,8,8,10: (8×10-8)÷3=24 ;3!× 8 ÷ (10-8) =6 × 8 ÷ 2 = 24 .【3!=3的阶乘=1*2*3=6】
6,9,9,10: 9*10/6+9=15+9=24.
1,3,9,10: 3*(1+10)-9=24.
收起
1 10*(4-1)-6
4 (5+7)*(10-8)
其他的想出来再补充
