Abacus mental arithmetic is an activity to calculate numbers through thinking and get results. It is a calculation in the brain by using the abacus representation as the carrier and the abacus rules. Since humans began to have the concepts of numbers and numbers, and can calculate the simplest numbers, there has been mental arithmetic.

In principle, the younger you learn abacus mental arithmetic, the better, because the growth of human intellectual brain cells has been completed before the age of three, and it has grown to 12 from the age of four to 100. The learning process of abacus mental arithmetic must strengthen the establishment of images through the proficiency of abacus operation, and the growth of brain cells is the driving force of image establishment. On the other hand, adult brain cells, because of their rigidity, cannot make their intelligence, thinking ability, memory and imagination grow more actively with the help of abacus mental arithmetic, that is, they cannot produce mental arithmetic images.

However, in the physiological structure, abacus mental arithmetic learning belongs to highly technical operational learning, and the coordination and balance of the body are extremely important. Too young to learn, because the nerve coordination and sensory balance of the small muscles of both hands have not been finalized, there are often problems such as incorrect posture or poor pen grip. In addition, the teachers in the market are mixed and the teaching concept is not correctly guided, which is more likely to destroy the number sense of learners, and it may get twice the result with half the effort to regain confidence in the future.

Extended data:

According to a survey conducted by the China Association of Abacus Mental Arithmetic, some educators question the education of Abacus Mental Arithmetic for seven main reasons:

1 "Increase children's learning burden";

2. "Not conducive to the all-round development of children";

3. "After the popularization of computers, it is useless to learn mental arithmetic";

4. "The role of abacus mental arithmetic education in developing children's intellectual potential is in the stage of intuitive observation and experience description, which cannot be confirmed by the results of comparative experimental tests";

5. "It remains to be seen whether the intellectual potential developed by abacus mental arithmetic can be maintained for a long time";

6. "Whether abacus mental arithmetic has universality and popularization value needs to be studied";

7. "The brain mechanism of mental abacus to develop children's intellectual potential can't be explained by modern brain science and educational psychology".

In response to these questions, with the support of the Ministry of Finance and the Ministry of Education, China Abacus Mental Arithmetic Association concentrated its efforts on the "Comparative Experimental Research on the Development of Children's Intellectual Potential through Abacus Mental Arithmetic Education". Through on-the-spot investigation, they conducted a comparative experimental test of abacus mental arithmetic education nationwide.
