Chronology of events

Dear par­ti­cipants!
Regis­tra­tion is open for the final stage of the Olympi­ad, which will take place on March 9 from 10 to 14 loc­al time (Time and date may vary in some coun­tries, exact inform­a­tion can be found in the list of ven­ues in your per­son­al account. The time in the inform­a­tion sys­tem is Moscow time. We recom­mend check­ing the inform­a­tion a couple of days before the Olympi­ad, as the organ­izers may adjust the start time of the Olympiad).

To select a ven­ue in your per­son­al account, you need to:
1) go to the «Olympi­ads» section;
2) find the Olympi­ad «Math­em­at­ics 2024–25» in the table of Olympiads;
3) click the green «Open» but­ton under the words «Final Stage» next to your class number;
4) put a check mark next to the appro­pri­ate ven­ue. You don’t need to do any­thing else, just a check mark.

If you have not fully entered the per­son­al data required for par­ti­cip­a­tion, the sys­tem will offer to do so.
If you do not see a win­dow to register for the final stage, write to isys@​formulo.​org.
On the page with the list of sites at the top you will see your par­ti­cipant code; write it down and take it with you to the Olympi­ad. The code must be indic­ated on each page of your Olympi­ad work. We also recom­mend writ­ing down the organ­izer­’s phone num­ber (in the descrip­tion of the site).
We recom­mend arriv­ing at the selec­ted site 10–15 minutes before the spe­cified time to find the right room. You must have an iden­tity doc­u­ment with you, as well as a blank A4 sheet of paper. You must not use phones or oth­er means of com­mu­nic­a­tion dur­ing the Olympiad.

❗️ In-per­son sites are planned in Bul­garia, Mol­dova, Romania, Tur­key and Uzbek­istan. Please stay tuned for updates.

❗️ If there is no ven­ue in your region, you can con­tact the organ­iz­ing com­mit­tee to dis­cuss its organ­iz­a­tion. The final decision will be made after approv­al by the man­age­ment. To do this, you need to con­tact Alexandra.

Inform­a­tion about ven­ues and regis­tra­tion will be avail­able later.

Please stay tuned for updates.

Dear par­ti­cipants!

Pre­lim­in­ary res­ults of the qual­i­fy­ing round are now avail­able. You can view them in your per­son­al account.

You can file an appeal in your per­son­al account (appeals are accep­ted until 23:59 on Janu­ary 18 Moscow time). Appeals are accep­ted ONLY in your per­son­al account, where the jury will post a response to your request with­in a few days after submission.

The sum­mary table and passing scores will be pub­lished after the appeals are processed.

We attach files with solu­tions to the problems:

• Rus­si­an
• Eng­lish

The date of the final round is cur­rently being confirmed.

The qual­i­fy­ing round of the Olympi­ad is over!

The res­ults of the qual­i­fy­ing round of the Olympi­ad will be pub­lished on the web­site no later than Janu­ary 20, 2025.

Dear par­ti­cipants, the Olympi­ad organ­iz­ing com­mit­tee has decided to extend the Olympi­ad by 1 day.

Solu­tions can be sent until Novem­ber 11, 2024, 23:59 Moscow time.

Dear par­ti­cipants, regis­tra­tion in your per­son­al account is avail­able again.

Good morn­ing!

Dear par­ti­cipants, we have a major fail­ure. Over 2000 accounts have been registered in the last few days. Unfor­tu­nately, many people make a mis­take in their email address when regis­ter­ing, so our serv­er is tem­por­ar­ily blocked.

The organ­iz­ing com­mit­tee is already dis­cuss­ing the pos­sib­il­ity of extend­ing the qual­i­fy­ing round. We will def­in­itely let you know!

The Olympi­ad tasks are avail­able on the web­site. You can solve them without regis­tra­tion, and after restor­ing access, enter them into the system.

We apo­lo­gize!

Dear par­ti­cipants! We have received many cla­ri­fy­ing ques­tions regard­ing the con­di­tions of the problems.
Many of them are answered in the con­di­tions, but there are sev­er­al cases where the con­di­tions are for­mu­lated impre­cisely or ambigu­ously. There­fore, we provide comments.
In the fol­low­ing text, the prob­lem num­bers are indic­ated as fol­lows: «8.1» means «prob­lem #1 for the grade R8».

6.7, 7.5, 8.5. Sofia takes one or more pho­tos FROM THE TOP of any pile.
9.1 (about the king of the class): it is known that there were at least four tests. Phrase (с) means that STRICTLY LESS par­ti­cipants dropped out in the first test than in any oth­er test.
5.5. Each boy knows EXACTLY four girls.
7.6, 8.6, 9.6. Only the inter­ac­tion BETWEEN the two selec­ted chil­dren is observed — they can still pass cheat sheets to the REST of their acquaintances.
9.7, 10.7. It is neces­sary that no sub­set of rect­angles form a rect­angle IN THE PLACE where they are ini­tially loc­ated. That is, for example, if two 1×1 squares are found some­where far from each oth­er, their uni­on DOES NOT FORM a rectangle.

Dear par­ti­cipants,

A small cla­ri­fic­a­tion for prob­lems 6.7, 7.5, and 8.5 is required. In each of her moves, Soph­ie takes one or more pho­tos FROM THE TOP of any stack.

Here is the qual­i­fy­ing (remote) round of the competition.

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.

You do not need to repeat the text of the prob­lems in your paper. The solu­tions should be writ­ten in Rus­si­an, Eng­lish, Ger­man, Span­ish, Uzbek, Turk­ish, Esper­anto, Farsi or French . Use of oth­er lan­guages should be agreed with the organ­izers in advance.

Dear par­ti­cipants!

The start of the qual­i­fy­ing round is just around the corner.

Please do not worry that there are no cur­rent Olympi­ads in the «Olympi­ads» sec­tion of your per­son­al account.

We do not have pre­lim­in­ary regis­tra­tion for the Olympiad.

The Olympi­ad itself, the con­di­tions and the form for sub­mit­ting answers will be avail­able in your per­son­al account start­ing from Octo­ber 20 (the day the Olympi­ad starts).

The Olympi­ad is con­duc­ted in two stages, the first of which (the qual­i­fy­ing round) takes place in the autumn, and the second (the final round) takes place in February-March.

The qual­i­fy­ing round is con­duc­ted in an online format using remote edu­ca­tion­al technologies.
Dates for the online qual­i­fy­ing rounds:
Math­em­at­ics: 20.10.24 — 10.11.24
Phys­ics: 16.11.24 — 07.12.24
Eng­lish: 20.10.24 — 13.11.24

The final round is (usu­ally) held in per­son at region­al venues.
To par­ti­cip­ate, you need to register in our inform­a­tion sys­tem (re-regis­tra­tion is not neces­sary). On the day the Olympi­ad begins (20.10.24), all the neces­sary inform­a­tion will be sent to your email.

Win­ners of the Olympi­ad receive a spe­cial vouch­er for edu­ca­tion­al camps «For­mula of Unity».

You can also find all inform­a­tion about the Olympi­ad on the offi­cial page at the portal olimpi​ada​.ru.

For a more suc­cess­ful par­ti­cip­a­tion in the Olympi­ad, we recom­mend solv­ing prob­lems from pre­vi­ous years and study­ing the recom­men­ded lit­er­at­ure. You can also pur­chase col­lec­tions of Olympi­ad prob­lems from pre­vi­ous years in print.
