What is the Putnam?

The Putnam is an annual mathematics competition for college students, and a fun way to expose yourself to new challenging math problems. The exam is held on the first Saturday of December, meaning Saturday, December 2, 2017.

Here is the Putnam Mathematical Competition website, and here is the Wikipedia page.

What is the Putnam seminar?

We will be holding weekly practice sessions, during which we will try to solve interesting problems together. The emphasis will be on learning from each other (not on competition), so please stop by and share your ideas. It's definitely okay if you can't make some of the practice sessions.

You are welcome to attend the practice sessions even if you can't make the exam, and you are welcome to take the exam even if you can't make the practice sessions.

In Fall 2017 we will be meeting weekly on Mondays at 4:00pm, in Weber 201. Our first meeting will be on Monday, August 28.
