Abstract

It’s 6:00 in the morning, and you’re watching the sunrise after a long night of clubbing in Ibiza, Spain. You bite into a warm waffle that you bought from a place nearby that you have already forgotten. As your toes sink into the cool sand and you start to think about the events of the night, your mind starts wandering towards math, towards Beach Math. These problems are for your most contemplative moments, in Ibiza or anywhere you might happen to be. We hope you like them!
