“算24点”方法技巧
“算24点”作为一种扑克牌智力游戏,还应注意计算中的技巧问题。计算时,我们不可能把牌面上的4个数的不同组合形式——去试,更不能瞎碰乱凑。这里向大家介绍几种常用的、便于学习掌握的方法:
1.利用3×8=24、4×6=24求解。
把牌面上的四个数想办法凑成3和8、4和6,再相乘求解。如3、3、6、10可组成(10—6÷3)×3=24等。又如2、3、3、7可组成(7+3—2)×3=24等。实践证明,这种方法是利用率最大、命中率最高的一种方法。
2.利用0、11的运算特性求解。
如3、4、4、8可组成3×8+4—4=24等。又如4、5、J、K可组成11×(5—4)+13=24等。
3.在有解的牌组中,用得最为广泛的是以下六种解法:(我们用a、b、c、d表示牌面上的四个数)
①(a—b)×(c+d)
如(10—4)×(2+2)=24等。
②(a+b)÷c×d
如(10+2)÷2×4=24等。
③(a-b÷c)×d
如(3—2÷2)×12=24等。
④(a+b-c)×d
如(9+5—2)×2=24等。
⑤a×b+c—d
如11×3+l—10=24等。
⑥(a-b)×c+d
如(4—l)×6+6=24等。
例题1:
3388:解法8/(3-8/3)=24 按第一种方法来算,我们有8就先找3,你可能会问这里面并没有3,其实除以1/3,就是乘3.
