Lots of maths puzzlesHello all, Last edited by bilalbadawi (20110301 10:37:02) #2 20110227 15:43:55
Re: Lots of maths puzzlesHi bilalbadawi;
That statement sure made me think. When working the motto is the exact opposite. "Do not think about the problem just solve it!" I was thinking how can can anyone ever reconcile these two thoughts? In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20110228 00:06:23
Re: Lots of maths puzzlesThanks Bobby. Some of the problems are classics indeed, but it is good to have all nice puzzles gathered in one place. #4 20110228 00:14:56

Re: Lots of maths puzzles"2Hell VS Heaven (*)" could be hard, if a person just doesn't think exactly how to word the question. Once the right question is realized, then it seems too simple. Correct? That was a neat puzzle. It might be as easy, or as hard, for a middle school student to answer it as for a much older adult to answer it. Either way, I still thought that it was a good puzzle. #7 20110301 10:33:47
Re: Lots of maths puzzles@Fermat'S: Anytime :D. As explained in the home section, no solutions are provided. If you give enough thoughts to a puzzle and feel you are stuck, I am happy to give a hint or check your solution... #8 20110301 11:02:44
Re: Lots of maths puzzlesThanks. I was discussing that very problem with someone else and I think we found a more concise, but perhaps more subtle, way to explain it than the way I explained it before. #9 20110301 11:19:44
Re: Lots of maths puzzlesThat's the solution I know. But the solution you gave is more intuitive, although longer to explain. From a pedagogical perspective, I prefer the first solution you gave. Esthetically, the second solution is better. Cheers!
