The manual contains 3000 mathematical examples on the topics of “Addition and subtraction”, “Multiplication and division”. The original construction of the material allows us to ensure a deeper assimilation.
As practice shows, the student completely mastered the program if he decides and writes the answer after 4-7 seconds. In this case, we can say that the account skill is brought to automatism.
Each page shows 5-7 columns an average of 52 example. At the end of the column, time is recorded. In the lower left corner, control numbers are indicated: the ideal time of solving one column, satisfactory and the result that should make the student think about. To achieve excellent results, every day you should solve one page.
