Which is better, abacus mental arithmetic or traditional arithmetic? Why?

The so-called abacus mental arithmetic is abacus mental arithmetic. Abacus calculation, using abacus as a tool, is used to calculate four operations of addition, subtraction, multiplication and division of multi-digits, square roots and other problems. There are certain rules and formulas in the skill of transporting beads. When the user can skillfully operate the abacus, he can not only get the correct answer quickly, but also describe the disk type, grade and floating change of beads in his mind through the growth of brain cells, that is, it seems that there is a "living abacus" in his mind, and the image of this living abacus is called a "virtual disk". It completes abacus calculation in the brain through the process of perception, image and memory, which is what we call abacus mental calculation.

Abacus mental arithmetic, skilled calculation speed is faster than electronic calculator, and the speed is amazing. Often, as long as you hear the number of questions or see the calculation questions yourself, the calculator can blurt out the answers or write them out immediately. Therefore, the abacus mental center is the best computing technology in the world today.

[Edit this paragraph] The value of mental arithmetic.

A person's intellectual development is closely related to regular finger exercise, and the operation of abacus is faster, more detailed and more subtle, which is more in line with this principle. Many educational research experts at home and abroad believe that abacus mental state is the advanced stage of abacus, which is more helpful to develop intelligence.

Because the human brain is divided into two hemispheres. The left hemisphere (left brain) is mainly responsible for the theoretical functions of reasoning, thinking and judgment, such as speaking, writing and calculating. The right hemisphere (right brain) is mainly in charge of the perceptual ability or emotional musical ability of describing, imitating, imagining and other spatial structure forms. The process of mental arithmetic in abacus is a combination of comprehensive thinking and practice. When calculating, it is necessary to count instantly, make a virtual bead image, simulate the strokes of beads, internalize the bead image, and strengthen thinking ability, memory, attention and spatial imagination to complete the calculation task. Therefore, when doing mental abacus calculation, we need the cooperation of the left and right hemispheres. In other words, abacus mental arithmetic is the golden key to developing intelligence.

Who is suitable for abacus 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 yet been finalized, there are often problems such as incorrect posture or poor pen grip. However, the teachers in the market are mixed and the teaching concept is not properly guided, which is more likely to destroy the learner's "number sense" and regain self-confidence in the future.

Therefore, it is suggested that the entry age of learning should be between 4- 12.
