American Mathematical Monthly Problems

The American Mathematical Monthly is an expository journal intended for a wide audience of mathematicians, from undergraduate students to research professionals. Each issue has a Problems and Solutions section where new problems are proposed.
Below you can find the solutions that I have recently submitted (pdfs will be available after the deadline). In the past years I gathered a pretty large collection of problems&solutions (but beware of nerd sniping ):
