Your puzzle for this

year's Advent calendar!

Each December, when others are hiding chocolates, MATH+ challenges high school students, university students, teachers, and everyone interested with tricky mathematical brainteasers.


The MATH+ advent calendar consists of 24 puzzles, which are released in both German and English. In a simple but fun way, they illustrate that math is fascinating, creative, and useful. Every year, the puzzles are invented by MATH+ researchers and their colleagues from the Dutch initiative 4TU.AMI.

Each year we publish the challenges and solutions in English andd German on Zenodo, such that they can be used for mathematical education beyond Christmas time

The most diligent participants have the best chance to win one of many great prizes. The festive award ceremony takes place in January in Berlin.


Project coordinators are Margarita Kostré and Lukas Protz, available at
