I am sorry I do not know what you mean by "this problem". Your 14-10 problem is solved already. I also solved it. Yes, I used a big assumption yesterday, but I have showed it is correct. Do you think my proof is wrong or something? I did not try to do it yesterday because you did not think this was a problem until today.

Well, you might have some simple reason, and some others might have other good reasons (this is possible because people have different viewpoints and the math God makes them meet eventually). I want to hear all these reasons instead of finding them myself. Like luantan said, it is just a game.
我是不该做那两个评论,我道歉。可是你可以直接说呀。何必这样做呢?一直说我的假定不成立,后来又好像早就知道那个假定是成立的,岂不是前言不搭后语?现在坦白了是要给我 hard time, 真是少见了。并没有什么 hard time, 我不会为做不出来一个题目伤心的。要是那样,fzy 那些题目让我都不敢来这儿玩了。
