Mental calculators from all over the world are invited to the 8th Mental
Calculation World Cup 2018!
The Mental Calculation World Cup 2018 will be held in Wolfsburg, Germany
Venue: Science Centre Phaeno (http://www.phaeno.de)
Date: 28-30 September 2018
Calculators will have to solve tasks in different categories (addition,
multiplication, extracting roots, day-of-the-week calculations) and
various surprise tasks.
Only strict mental calculation (no tools, no writing down of
intermediate results) is allowed.
There will be several titles and trophies for the best participants.
In particular, the MEMORIAD Association will sponsor free flights to the
MEMORIAD 2020 competition (planned to be held in Dubai, USA)
(http://www.memoriad.com) for the winners in the categories addition,
multiplication, square roots and calendar calculation as well for the
winner of the combination.
(does not apply for participants who are not allowed to enter MEMORIAD
contests according to decisions of the MEMORIAD Association).
The registration form can be found on the MCWC web site
Calculators who already took part at a previous MCWC event are welcome
to send the application form by e-mail to firstname.lastname@example.org.
First-time participants please download the entry form on the MCWC web
site. Please send it by airmail together with the documentation that is
necessary for qualification to the address given in the form.
Please note that we have a tough qualification (with usually far more
than 40 people registering). Calculators who took part in one of the
previous years may want to send additional documentation about their
recent results in the same way as the first-timers (by airmail with all
the paperwork) in order to have better chances in the qualification.
Deadline for Registrations: 1 June 2018
You can help us with the organization if you register soon.
The number of participants is limited to 40. If more people register for
the event, the organizer will select the participants who qualify. For
this purpose, information about previous results at mental calculation
events (achieved in the past ten years), other mental sports contests
and verified achievements with the Memoriad software
(http://memoriad.com/memoriadsoftware.asp) are taken into consideration.
The results achieved should be documented (category, number of correct
answers, time) and sent together with the application form. These
results must be confirmed by a witness with some background in mental
calculation (for example a maths teacher or a university researcher who
works in a field close to mathematics).
There is no entry fee, but participants have to pay their travel
expenses. We will publish hotel recommendations soon enough on the MCWC
Please contact us soon enough if you need a formal invitation letter for
visa purposes. Keep in mind that in some countries visa formalities can
take a long time!
