Here is the qualifying (remote) round of the competition. You can solve problems until November 12, 2018.
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 2017/18 (those with Diplomas I‑III) can participate directly in the final round.

How to submit solutions
The solutions should be submitted to the Jury by November 12. If you have 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).
Before submitting your solutions, please fill in an online-questionnaire. Then you can email your solutions to firstname.lastname@example.org (from the address indicated as your email address in the questionnaire). You can attach several files or create a .zip archive. Please indicate your grade of participation (R5, …, R11) in the Subject line.
Alternatively, you can download a pdf file of the questionnaire and add your answers or create a text file in another common format. Please attach your questionnaire as a separate file to the same message.
You can send your questions to the organizers (but not the solutions of problems) to email@example.com.
