Dear friends of the MATH+ Advent Calendar,

Due to a longer period of illness, the Advent calendar team was not yet able to provide you with the solutions for the 2020 challenges.

We are busy working on the solution book and the notification of the winners and kindly ask for your understanding and some more patience.

Have a look at the discussion board for solutions that other participants provided.

Thanks,
Your MATH+ Advent Calendar team
