The 12th All-Russian educational and entertaining math flash mob "Math Test for Adults and Not Only 'MathCat'" took place in Russia. This year, the event took place at 927 locations in 86 regions of Russia and 12 countries (Australia, Armenia, Belarus, Egypt, Kazakhstan, Kuwait, Moldova, Norway, Serbia, Turkey, Uzbekistan, and Montenegro). This math celebration is designed for everyone aged 10 and up.
Peter the Great St. Petersburg Polytechnic University became one of the flash mob's offline venues for the second time. Each participant was given four sets of problems, corresponding to four difficulty levels: easiest, easy, medium, and advanced—with 10 problems in each level. The flash mob organizers called these levels "leagues": "white," "green," "yellow," and "red," respectively. After assessing their abilities, participants independently and voluntarily chose one of the leagues to solve. Each level consisted of ten problems. Solving the easiest problem earned participants 5 points, while solving the most difficult one earned 15. Furthermore, this year, a time factor was used for the first time to determine the winner: in the event of a tie, the participant who submitted the solution first was ranked higher. Participants were given 1.5 hours to solve the problem, and most used the entire allotted time. After submitting their answer sheets, participants received personalized certificates from the organizers right in the classroom.
On the day of the event, 202 people attended the site, significantly more than the previous year (144 in 2024), the majority of whom were SPbPU students. At the university site, 23 participants chose the White League (12%), 24 chose the Green League (12%), 33 chose the Yellow League (16%), and 122 chose the Red League with advanced problems (60%). In this regard, our site differs significantly from the national average, where traditionally more than half of participants participate in the White League.
Several participants, including faculty from the SPbPU Department of Higher Mathematics, competed in double and triple team competitions, along with a friend or two (in these cases, participants chose different difficulty levels). For the first time, the Polytechnic University also hosted quadruple competitions!
The Institute of Physics and Mathematics (IPM) of St. Petersburg Polytechnic University (SPbPU) organized the event. Leading the way for staff and students, Department Head Ilya Sysoev also participated in the flash mob. The event was coordinated by the Institute's Deputy Director for Research, Marina Sysoeva, and leading specialists from the IPM Directorate, Elena Naumova and Natalia Akhiyarova. Volunteers—SPbPU students from various years and institutes—made a significant contribution to the organization.
At each site, winners and runners-up who score the maximum number of points for solving problems of the chosen difficulty level receive diplomas and souvenirs.
