Welcome to Fiddler on the Proof — or, as we like to call it around here, The Fiddler.
Starting Friday, July 7, I’ll be posting a mathematical puzzle for readers to solve each week. These puzzles are designed to challenge and delight you. You’ll have several days to come up with a solution and submit it. The following week, I’ll reveal the solution, give shoutouts to those who submitted exceptional work or explanations, and congratulate a winner chosen at random from those who submitted correct solutions.
So dust off those old puzzles laying around your desk (my inbox is always open for great puzzle ideas), sharpen your pencils, and boot up your mathematical software. Together, let’s keep the fun going!
