游戏

上来冒个小泡。周末家人朋友一起庆虎年时玩扑克，受到小时候玩的游戏的启发，我同大家玩算24点。花牌去掉，用1-10个数，4个人各出一牌，加减乘除等所有数学运算都能用，但每个数字只能用一次。谁最先算出答案24且算法准确，谁就赢，但要等其他3人完成，交流答案。最后算出的或算不出的统吃那4张牌。第一个用完牌的是赢家，牌最多的是输家。现有这么4张牌请大家玩玩：3，4，6，7。算出的兄弟姐妹们要记时间哦。恕太忙不能回复大家。今晚给答案啦。

• 回复：3 x 7 + [6 ÷ square root of 4] = 24 -longhair- ♀ (72 bytes) () 02/08/2010 postreply 11:38:39

• 3 x 7 + [6 ÷ square root of 4] = 24 is wrong, I guess -5thgirl- ♀ (15 bytes) () 02/08/2010 postreply 13:49:18

• 7 mod 3 =1, 1x4x6=24 -- can we use mod? -greenlawn- ♀ (0 bytes) () 02/08/2010 postreply 18:49:46

• Similarly ((3 ^ 4) mod 7) x 6 = 24 -greenlawn- ♀ (0 bytes) () 02/08/2010 postreply 19:01:14

• 找到这个，只用加减乘除不可能算出24的组合。3/4/6/7在内。 -greenlawn- ♀ (160 bytes) () 02/08/2010 postreply 19:05:08
