2017年10月28日 · Like the title says, I'm looking for math problems that are easy to understand, but difficult to see the solutions immediately or even after much thought; but when shown the solution, the solution is easy to understand. There's this "poisoned wine challenge" problem which is a pretty great example of this. (PBS infinite series made a video on ...

2012年7月1日 · I request people to list some moderately and/or very famous open problems which high school students,perhaps with enough contest math background, can understand, classified by categories as on arxiv.org. Please include statement of the theorems,if possible, and if there are specific terms, please state what they mean.

2011年6月15日 · The problems may presuppose mathematical knowledge up to but not including Calculus. For my purposes, a good problem is one that emphasizes cleverness over knowledge. For example, "Find the area of this triangle given some information" is a bad problem, since it's solution is likely just a matter of knowing lots of different facts about triangles.

2014年12月27日 · I am working on a project presentation and would like to illustrate that it is often difficult or impossible to estimate how long a task would take. I’d like to make the point by presenting three math problems (proofs, probably) that on the surface look equally challenging. But… One is simple to solve (or prove) One is complex to solve (or ...

2024年7月11日 · This particular problem is quite simple for an Olympian. Since you can not solve it in 30 minutes, try doing simpler questions that are not Olympiad level. For example, the AMC and AIME series of questions are excellent. Simpler questions allow you to learn methods of solving problems in less time than doing Math Olympiad problems.

2015年12月24日 · It is not completely elementary, but Abel's proof of the Abel-Ruffini theorem is quite short, 6 pages, and can with a bit of introduction be understood by someone without a degree in mathematics.

2014年6月5日 · As you work more and more on math problems, you start to be able to work longer without becoming discouraged. For example, $30$ minutes may seem like forever now, but after working on a ton of (hard/stretching) problems, you'll probably think it seems small. Always stretch/push yourself, and never lose track of why you're solving the problem.

2010年8月10日 · tkz-euclide is a package for embedding, into Tex, drawings of Euclidean constructions. That is, it supplies commands to draw straight lines and circles but nothing any more sophisticated e.g. ellipses or the graphs of arbitrary functions.
