one question:
x/12 is an integer. x/11, the reminder is 8, what is the reminder of x/8..
my answer is 0.
can anyone helps me to solve the question?

我是这么做的,比较土的办法:
x=12n     
x=11m+8  so  12n=11m+8  
然后为了方便  m= (12n-8)/11  m必须是整数
试出当n=8 时m=8
于是x=96  96/8  余数就是0了
应该有更简便的方法,我马上有课就先这土办法上了:)

这题的答案不一定是0. 如果N=19的话, 则余数为4.不知我的计算是否有误.

good question!

我也算过了,是0,4,0,4,0交替出现,
在本周的JJ里题目改变了一点,
被12除余0,被11除余7,问被8除余多少,
答案也是4,0,4,0,4,0交替出现
大家可以讨论!
