when did mental arithmetic appear and how it works
This is a unique technique that was created in China over 5 thousand years ago.
In Japan, mental arithmetic is a compulsory subject from which children begin their education in school.
Mental arithmetic is a technique that teaches rapid mental arithmetic. In the course of mental calculations, two hemispheres of our brain begin to work, and children simultaneously develop creative and logical thinking.
Scientifically proven! Relevant studies were made in China in 2002, as also in India and the UK. As a result of systematic studies, children significantly improved their performance not only in mathematics, but also in other disciplines. Also, thanks to the course of mental arithmetic, all children have improved visual, auditory memory, and increased concentration of attention.
