The family is very practical small teaching AIDS, the baby can recognize, ten, hundred, thousand, ten thousand, etc., is the parents to the baby enlightenment education ideal teaching AIDS. Due to the convenient and fast calculation of abacus, it has been a commonly used computing tool of the han nationality for thousands of years. Even the most advanced electronic calculator can not completely replace the function of abacus

Abacus arithmetic, colloquially speaking, is to use an abacus in the brain. Abacus mental calculation is based on the abacus, making the abacus operation process fully \"internalized\", so as to completely get rid of the actual external action of the abacus, relying on this \"internalized\" \"mental abacus\" (also known as \"virtual abacus\") in the brain to add, subtract, multiply, divide and other calculation methods. Abacus mental arithmetic itself has the characteristic of group calculation, which is undoubtedly helpful for children who have difficulty in grasping the calculation of large Numbers to master the concept of logarithm and overcome the phenomenon of children counting one by one. The \"five-liter decimal system\" of abacus mental arithmetic greatly reduced the difficulty of carry. The characteristics of abacus mental arithmetic model can promote the improvement of children's computing ability.

Do you still need to learn abacus mental arithmetic in the computer age

     Some people say that nowadays, with the rapid development of computer technology and information, learning abacus mental arithmetic is not a backward step. With planes, trains, cars and motorcycles, are bicycles still useful? Each has his merits. Computers are useful, time-saving and accurate, but they are not the foundation of mathematics. Abacus mental arithmetic is different, it allows students to really understand the whole process of operation, which is a very important link in mathematics. To learn mathematics well, we must understand the whole process of calculation, only know the answer, but do not know the reason, which is not conducive to the development of thinking ability. It can only be said that the computer is a tool for calculation, and mental arithmetic helps to develop the functions of intelligence.
