Mental Calculation


Rome, Saturday 9th April 2022

Università Luiss Guido Carli

25 November 2021


The training test to prepare for the 2022 Mental Calculation Championship is available in PDF format, in the menu on the left.

The test is unique for all categories.
In each paragraph the questions are proposed in order of difficulty and it is not necessary to answer all of them: everyone should reach as far as they can answer. Broadly speaking, the questions with a WHITE background are accessible to everyone, those with a LIGHT PINK background already require a certain level of preparation and those with a DARK PINK background can only be solved by those who are truly experts.

So go as far as you can, the aim is to participate and have fun… not necessarily become a champion.

Many of the operations proposed in the test may appear more difficult than they actually are, but in reality there are shortcuts that greatly simplify the solution. All the possible shortcuts are dealt with in the volume Il grande libro del calcolo veloce e mentale (The great book of fast and mental calculation) by Dario De Toffoli, which will be distributed by Kangourou in the second half of February to all schools belonging to the Association and in the same period it will also be available in bookstores in the Mondadori edition.
