The new world champion in mental calculation for children up to 12 years old is Bulgaria's Kaloyan Geshev, a 6th-grade student at Sofia's 125 Boyan Penev School. 

At the World Mental Calculation Championship held in the city of Bielefeld, Germany, the Bulgarian boy achieved an incredible score of 2,217 points, with which he won the gold medal and the world title. 

Kaloyan Geshev managed the tasks of addition, subtraction, multiplication, division, square roots, cube roots, fractions, currency conversion, conversion of measurement units, calculation of calendar dates and many others in less than two hours. He only had a sheet of paper for writing down the answers.

56 children from 13 countries participated in the competition and for the second time in its history a child from Europe became the winner.
