1.11.12.13这四个数算24点怎么算

Answer 1

(13-11)*1*12

二十四点计算技巧

1、若数中有2、12、4、6；3、8中的一个数，可用其他数凑成另一个数相乘。

如3、6、7、7，可以用3×（7-6+7）或6×（3+7÷7）

2、若数中无这些数，可以两两结合得到这些数相乘。

如5、1、7、1，可以用（5-1）×（7-1）或（5+7）×（1+1）

3、利用3×8=24、4×6=24、2×12=24求解。

把牌面上的四个数想办法凑成3和8、4和6、2和12，再相乘求解。实践证明，这种方法是利用率最大、命中率最高的一种方法。

4、利用0、1的运算特性求解。

如3、4、4、8可组成3×8×（4÷4）=24。又如4、7、1、1可组成4×1（7-1）×1=24。
