24点之1 5 5 5
1. 常规方法：
5*(5-1/5)
2. 几个特殊运算：
(5-5/5*1)!=4!=4*3*2*1=24
(5-1*5/5)! 1*(5-5/5)!
(5-1)!*5/5 5!/(5+5mod1)=5!/(5+0)
√5 * √5 *5-1
24点之2,4,7,8
4*7-8/2=24
加减乘除的如上！
24点之2 2 7 9
(√2*√2-7+9)!=4!=24
(√2^2-7+9)!=4!=24
(7mod(√2*√2)+√9)!=4!=24
(7mod(√2^√2)+√9)!=4!=24
(-2+7)!÷(2+√9)=24
(2÷2+7)*√9=24
(√2÷√2+7)*√9=24
√2表示根号2
4！表示4的阶乘，即4*3*2*1
7mod2表示7对2求余，及7÷2=3余1
特殊运算如下：
4*7-√(8*2)=24
8*(7-2-√4)=24
8*(7-2*√4)=24
8*(7-2^(√4))=24
(2-7+8)!*4=24
(2+7-8)*(4!)=24
好好思考！
嗯二楼网友书说的网站我也知道，不过自己做题还是多思考下，方法越多越巧妙越好！
本身24点就是锻炼大家的思维能力的，也希望大家能正确使用该网站，只是核对答案而非直接取结果！
