On the fifth day of the Olympiad, the participants learned about the criteria for evaluating the solution of problems, looked at their work and asked questions if they were not clear about the solution of the problem. After lunch, the participants could meet with the jury and members of the Coordination Council. During the meeting with Nazar Agahanov, Pavel Kozhevnikov, Dmitry Belov, and Charles Leytem, schoolchildren could ask questions about Olympiad Mathematics and how to prepare for high-level Olympiads.

For those who the Olympiad tour and the quest “Mathematical Running Maykop” were not enough, the organizers prepared a game “Brain Battle”. The game consisted of seven rounds, each with ten questions.

Round I - Guess the famous person from the photo;

Round II - Guess the famous person on a child's photo;

Round III - Guess the song played backwards;

Round IV - General knowledge quiz;

Round V - Guess what is hidden in the famous picture;

Round VI - Guess the country by the outline;

Round VII - Guess what is advertised in the poster.

Today was Round II of the Olympiad. As in Round I, participants had to solve four problems in four hours. Many participants found the tasks difficult, but interesting.

“The tasks were difficult. I do not think that I did well, but I solve half of them for sure. This is my first Olympiad of this level, so I'm just glad to be here.” Lada Stafeevskaya, a participant from the Rostov region (Taganrog).

 “My impressions... difficult, but interesting tasks. In my opinion, an interesting task was this one: there are five consecutive numbers, can the LCM be equal to a square? ”. Alexander Klets, a participant from the Krasnodar Territory.

After Round I of the Olympiad, the participants met with the Head of the Caucasus Mathematical Center of the Adyghe State University (CMC ASU), Director of School of Applied Mathematics and Computer Sciences at Moscow Institute of Physics and Technology (MIPT) Andrei Raigorodsky and the research advisor of the CMC ASU, the rector of the University Dmitry Pozharsky Professor MIPT Alexei Savvateev. The topic of the meeting was “About math in a fun and interesting way.”

In an interactive manner, Alexei Savvateev talked about the exponent, after which Andrei Raigorosdky continued the topic and showed that the exponent is a transcendental number. The meeting ended with arguments about diophantine approximations.
