I express my personal gratitude to the group of companies WOW Sochi for organizing the All-Russian Olympiad on mental arithmetic 2018 in Sochi. The staff showed their responsibility, proficiency and friendliness. As a result, 400 children and their parents were delighted with the event and the city! I hope for a long and profitable cooperation!
