Hilbert's Hotel Hunt | Mathematical Problem Solving 2

David explains how you can apply the five general problem solving techniques introduced in the previous video to solve the three problems he set last time: Cutting Up Chocolate, A Busy Bee, and Hilbert's Hotel Hunt. For the next video, you are tasked to think about the game of 21 dares, and see if you can come up with a winning strategy. UCL Maths Dept Twitter: @MathematicsUCL.
