If you're itching for more, then I have some suggestions:
- Come up with a problem
and send it to me at
.
I have run through much of my backlog of topics that
I want to write about. I want to know what other people find interesting.
- Visit Michael Shackleford's site at mathproblems.info. I've done the first 120 problems on that site, so feel free to e-mail me about any of them.
- Visit NRICH. They are an educational organization, and have a wide variety of content appropriate for grade school through high school (and into college). In addition, they have a number of puzzles worthy of adults with math degrees. If you are an educator, you might want to note that you can browse NRICH by topic, such as Algebra/Inequalities/Quadratic. If you are simply looking for puzzles, they have a variety of problems each month for different educational levels. (Look in the index for the current magazine for the link labeled "Problems".) The problems in the 15+ Challenges section are often challenging and enlightening.
- If you enjoy problems that are best solved with programming techniques, the Euler Project at mathschallenge.net offers some fairly challenging problems with numerical answers. The main site has a library of problems requiring high school mathematics and also a collection of cipher challenges.
- Visit Nick's Mathematical Puzzles. This is another well-constructed site with a variety of puzzles with solutions.
- Try some of Paul Hsieh's puzzles. He has a variety, including classic paradoxes and some true puzzlers I haven't seen elsewhere. He gives hints, but not answers.
