Math 'problem of the day' website?

November 20, 2004 9:45 AM

I enjoy mathematics, and I'd imagine that on these internets there are many others who are similarly inclined. Why then, am I unable to find a good "Problem of the Day" site? [mi]

A good mix of problem difficulty and type is preferable, ranging through calculus and above. Googling

Response by poster: Googling seems to return sites geared almost exclusively toward the low end of the K-12 spectrum.

Try adding the word "College" to your Google searches. That found me a few "Problem of the Week" and "Problem of the Month" sites at Stetson, Bradley, and Math Forum.

Try Mathpuzzle, including the extensive list of links.

Not "of the day" format, but some interesting stuff at Cut the Knot. And if you're looking for a real challenge...

That IBM site made my head explode.

Response by poster: Wow, great links, especially IBM! The current IBM problem is great, as are the questions in the archives, and I think I'm close to a solution for November.

CrunchyFrog: I can't believe I hadn't seen the MathFourm one, I go there rather frequently.
