Each week, a new challenge problem will be posted below.

If you attempt the problem and find a solution, you can submit your answer in the submission box below. We will choose the most elegant, creative, and well-explained solution and publish it on this website! Of course, you will be credited (unless you want to remain anonymous, which you can state in your submission). Additionally, your name will be mentioned in the solution video that will be posted on the Mathematticus channel.
