Start of the qualifying round

General principles

Here is the qualifying (remote) round of the competition. You can solve problems until November 13, 2017.

Please remember that your solution of every problem should include not only the right answer but the full reasoning as well.

We will be happy if your friends who like mathematics also participate. However, every assignment should be done individually; otherwise, your submission will not be considered.

Please be careful with preparation of your work, follow the rules and provide all necessary data. You do not need to include problem statements into your submission; please write down your solutions only.

You can write your solutions by hand and scan them or type them using a text editor. Solutions should be written in Esperanto, English, French, Georgian, German, Persian, Romanian, Russian, Spanish, Ukrainian, or Uzbek. Use of other languages should be agreed with the organizers in advance. For anonymous grading, you should not write your name on the paper sheets with solutions.

The winners of Olympiad 2016/​17 (those with Diplomas I-III) can participate directly in the final round.

How to submit solutions

Before submitting your solutions, please fill in a questionnaire. (Download it in Excel format if MS Excel is available. Otherwise, download it as pdf and add your answers or create an .odt or a .txt file.)

The solutions should be submitted to the Jury by November 13. If you received any instructions from your local organizing committee or a teacher, please follow them.

Otherwise, please type or scan your solutions into one of the following formats: txt, doc, odt, pdf, jpg. The files should not contain your name (even in the file names). Then you can email your solutions to [email protected]​formulo.​org. You can attach several files or create a .zip archive. Please attach your questionnaire as a separate file to the same message. Please indicate your grade of participation (R5, …, R11) in the Subject line.
