Fiddler on the Proof
...is a weekly mathematical puzzle newsletter run by Zach Wissner-Gross. The problems have been a nice challenge every weekend, and I recommend everyone check it out and consider subscribing!
Puzzle submissions can include writeups/explanations. I've been using loose GitHub Gists for them in the past, and I figured they deserved their own pages at this point. I will slowly add my old solutions here over time.
