Hi all!
This is to inform you that the 4th Mental Calculation World Cup which will be held on 3-5 June at the University of Magdeburg, Germany. The event is part of the "Summer of Science" festival.


Each mental calculator will have to solve tasks in different categories (addition of ten 10-digit numbers, multiplication, extracting the square root from a 6-digit number, calculating the day of the week and surprise tasks).

There are several prizes for the best participants.

There will be two titles - one for the "fastest calculator" and another one for the "most versatile calculator" (with the best results in the surprise tasks). There are also titles for the best calculators for the categories addition, multiplication, roots and calendar.

All the competitions are about mental calculation without any aid. Registrations from calculation experts using the Abacus / Soroban are welcome either.
