World championship in mental calculation for adults

The Mental Calculation World Cup is the world's most important competition for mental calculators.

Since 2014, it has been held every two years at different locations in Germany. First venue was Annaberg-Buchholz, birthplace of Adam Ries. In the following years, the venues will continue to be related to mathematics and science. The championship was already a guest at the Mathematikum in Gießen, the Technische Sammlungen Dresden or the Phaeno in Wolfsburg.

In addition to the Andreas Mohn Foundation, the supporting partner is Memoriad, an international association for mental sports.

The number of participants is limited to forty.

If the number of registrations is higher, a qualification based on previously achieved results (achieved at other events or in standardised tests) will take place in advance. In 2018, for example, there were 79 registrations from 23 countries.

Participants ranged in age from 15 to 75 years. The principle is to invite the best calculators from all over the world. The exchange of knowledge and making contacts is even more important than the competition. Interested students are always welcome to attend lectures.

In the competition, the participants solve tasks from previously known standard categories on the one hand and six unknown surprise tasks on the other hand over two days.

Examples of tasks from previous years are:

14130214 x 17981822

57809355 + 28 x 16448333

or 

 √853748

In the course of a show event, which is offered to the public, effective achievements from memory sports and mental arithmetic will be demonstrated. In recent years, for example, there have been competitions such as "mental calculator versus pocket calculator" or the attempt to combine juggling and mental arithmetic. These events are open to all people, who are interested.
