Welcome! On the right, you'll find fun and challenging problems that require critical thought.

None of the problems involve a 'trick' definition, but none the less you'll need to think creatively to find the solution. Each problem is star-rated according to its difficulty, with one star being easy and five being extremely hard.

If you can't do one of the problems, don't worry. This website is meant more as a learning tool than as an examination! Bear in mind that academics often learn from each other and ask questions when they don't understand something. It's more useful to read the hints and the solutions than to become frustrated.

We hope you have fun!
