1 ,4,8,10,算24点怎么计算
答:1 ,4,8,10没有符合24点的计算的方法。24点计算简介:用加、减、乘、除以及小括号、中括号、大括号把四个整数连接组合起来,使其结果为24.24点计算表达式分成三类:1、 无括号的简单表达式。2、 有一个括号的简单表达式。3、 有两个括号的较复杂表达式。

史上最难算24点一个
答:分数类:3377,3388,1555 求全解类:2379,678(10),3569,2589,2468,248(10)大数类:44(10)(10),3578 。。。

1到10的自然数中,任意4个,有不能算出24点的吗??急!!!
答:有很多这样的数,只用加减乘除,有很多算不出来24点的,比如 1 6 7 8 , 9 5 7 7 , 3 4 6 7 , 9 7 7 8 等等,有很多这样的组合。

1,4,7,10的规律是什么
答:1、4、7、10这个规律,第n个数是3n-2。理由如下:3*1-2=1,3*2-2=4,3*3-2=7,3*4-2=10,3*5-2=13等。所以第n个数是3n-2。1、4、9、16、25,按这个规律,第n个数是n^2。理由如下:1^2=1,2^2=4,3^2=9,4^2=16,5^2=25……所以第n个数是n^2。1又1/^2,...

7,8,9,10怎么算24点
答:用7,8,9,10算24点的算法:﹙9×8﹚÷﹙10-7﹚=24。棋牌类益智游戏,要求四个数字运算结果等于二十四,一起来玩玩吧!这个游戏用扑克牌更容易来开展。拿一副牌,抽去大小王后(初练也可以把J/Q/K/大小王也拿去),剩下1~10这40张牌(以下用1代替A)。任意抽取4张牌(称为牌组),用加、减...

写十道得数等于24的算式,每次用4个从1到10的数
答:1~10数不重复选择有:(1).1+4+9+10=24(2).1+5+8+10=24(3).1+6+7+10=24(4).1+6+8+9=24(5).2+3+9+10=24(6).2+4+8+10=24(7).2+5+6+10=24(8).2+5+8+9=24(9).2+6+7+9=24(10).3+4+7+10=24(11).3+4+8+9=24(12).3+5+7+9=24(13).3+5+...

1,2,3,4,5,6,7,8,9,0的来历
答:因此随着历史的发展,阿拉伯数字逐渐在各国流行起来,成为世界各国通用的数字。补充 最古的计数目大概至多到3,为了要设想“4”这个数字,就必须把2和2加起来,5是2加2加1,3这个数字是2加1得来的,大概较晚才出现了用手写的五指表示5这个数字和用双手的士指表示10这个数字。这个原则实际也是我们计算的...

这组数列1,2,4,4,7,8,10,16,13,32,(),(),19,128怎样找规律括号内
答:1,2,4,4,7,8,10,16,13,32,(),(),19,128怎样找规律括号内 单数位置是:1,4,7,10,13……每相邻两数间相差3,所以后面是16。偶数位置是:2,4,8,16,32……前面数的2位是下一个数字,所以后面是64 ∴整个数列两个括号里分别是:16和64 ...
