This blog was created to manage the “Problem(s) of the Week” initiative. You can propose new problems, read the current problems, or write up solutions at the appropriate subpages.
Here’s a guide to using LaTeX in comments.
Schedule: New problems will be posted on Monday, and the page for proposing solutions will be created the following Thursday. The problems will be taken from those that you suggest. At this time, we expect there to be between one and three problems per week.
Props to Tepaps and AngelTC.
