What is the MATHEON-Kalender?


The MATHEON-Kalender is a free online competition.

Altogether 24 challenges, one appearing daily from the 1st to the 24th of December. Every challenge can be solved till December 31st. Students from High School, College, teachers and all other interested persons are invited to enter the contest.

The challenges have a festive character and are written by the mathematicians from MATHEON and 3TU.AMI, illustrating applications from their research projects.

And you can win some great prizes, which we raffle among the participants. With a little luck - independent of the number of your right answers - you can win something. Only our first prizes are raffled among those with the highest number of daily-given correct answers, see our rules for the game. 


After a short and easy registration with your email address you can start to puzzle over the challenges. More details can be found at the rules of the game. The registration starts at November 1, 2015.


Enjoy and good luck! Your MATHEON-Kalender Team
