Problems To Overdose On
Past columns recommended websites that provide interesting collections of problems. Often, university math departments will offer problem sets with differing motivations. Perhaps it is to recruit good mathematics students. Or, it might just be a faculty outreach to share their mathematical interests.
Some possible websites to visit, to find interesting problems:
I am sure there are others. For example, I have previously suggested the University of Washington's Challenge of the Week ....Plus, remember there is always (24/7) access to the Archived Problems of the Week on this MathNEXUS website.
And, if you know of other colleges, universities, or secondary schools that post weekly problem challenges, please let me know so that they can be shared.
