For the participation you only need an easy registration. By specifying a not yet assigned user name, choosing a password and a real email address, any user can set up his/her account. Registration is free, of course, and is possible from November 1, 2016 at 00:00:00 through December 31, 2016 23:59:59.

All worldwide participants (individuals), which have completed all mandatory fields in the "Profile" (marked with a *), are eligible to win at Matheon-Kalender.

The 24 challenges of Matheon-Kalender

From the 1st until the 24th of December one challenge will be published daily at 16:00:00 oclock (CET) on our website at the Matheon-Kalender. For each challenge ten possible answers are offered, of which only one is correct. The challenges are variegated. On beforehand, our high school teaching staff verified that each challenge is suitable for students from the 10th grade onwards. Our challenge writers, scientists from Matheon and our Dutch partner universities checked the tasks for correctness and uniqueness. The tasks are always uniquely solvable. There are no tricks.

Submission of answers

For each challenge ten possible answers are offered. You have to be logged in order to be able to choose one answer as your "solution". The deadline for all solutions is December 31, 2016 at 23:59:59 oclock (CET) . Until the expiry of this period it is possible to give an answer for every challenge. Therefore, a subsequent registration or later entering into the competition is not a problem since this deadline applies for each challenge of Matheon-Kalender. The submitted answers and the corresponding time stamps are stored in your account . After December 31, 2016 at 23:59:59 oclock (CET) submission of answers is not possible anymore.

The solutions

The correct solutions to all challenges will be published in January, as until the 31st of December answers to any of the challenges can be submitted. The correct answers will appear in the Archive. After the submission deadline (31.12.2016) lots will be assigned for each correct answer depending on the delivery time.
During the competition (i.e. until 31.12.2016) a submitted answer can be changed at any time. In this case the time stamp of the last modification will be taken into account.

Prizes and their assignments

Prizes are assigned among the participants of our competition. In "Sponsors & Prizes" the prizes are listed. This list will be updated during the calendar as soon as we get more prizes from our sponsors. Until 10th January 2017, the "Matheon-Kalender" team will draw lots. The winners will be announced in the List of Winners after checking the files. The lucky winners will be celebrated on 20 January 2017 at the TU Berlin. The main prizes will be raffled among all participating students with more than 95 lots. In addition there is also a lots pot for the students in the last year of high school, in the last-but-one year of high school , one for students in the category Non-graduate and a lots pot for adults.
All lots assigned in the various categories will be collected into the corresponding pots; THEREFORE also participants with only a small number of lots have the chance of winning great prizes. Some special prizes will be announced on the main page under News, others not.
Employees of Matheon and their family members are not eligible to win prizes.
There is no legal recourse.

Assistance

For reasons of fairness the "Matheon-Kalender" team will not answer to any substantive questions about the challenges nor will we provide any help.

Matheon-Kalender Forum

Furthermore, all participants of the Matheon-Kalender have access to an online forum. There the challenge creators are daily answering to questions about their challenge. There is also the possibility to leave directly feedback or to take part in the discussions in the forum.
Participation in the forum is subject to the usual code of good conduct for the Internet. Furthermore, in order not to spoil fair competition and game character, any hints to the right answer or to the solution of the challenges are not allowed.
The Matheon-Kalender Forum does not provide a platform for building groups to participate jointly; rather it allows for clarification of ambiguities and can also be used for having a good time (with or without math).
All users must abide by these forum rules.

Group work and group participation

You can participate in the "Matheon-Kalender" only as a single individual player. Registration as a group is not possible for technical reasons and for considerations about chances to win prizes. Nonetheless, we dont want to and can not prohibit group work (with individual submission of solutions) . We encourage group work provided it focuses on mathematical exchange and does not have the sole exchange of correct answers as its target. We are in favor of cooperation, because we consider it important to communicate about mathematics. We want to communicate fun with mathematics and it is most fun to do this together.
We cannot verify if group work degenerates into a "solution exchange group". We appeal to your fairness!
Furthermore, school classes are of course invited to follow the "Matheon-Kalender" and work on the challenges. After the submission deadline students can compare their results  checking in their accounts in the area "My Results" - with their classmates.

Publication ban

Neither our challenges nor the solutions shall be published in the Internet or elsewhere.

Our Privacy Policy

Exclusion from Matheon-Kalender

Distribution of solutions on the webpages of "Matheon-Kalender" and its Forum is strictly prohibited. Also any hints or hidden clues shall be omitted . A link to other websites is not allowed, as we can not guarantee for the content of external websites. Similarly, the multiple registration with different usernames is not allowed, as this would result in a higher chance for winning prizes and leads to exclusion from the "Matheon-Kalender" and its forum.
