# Mental arithmetic: what is it?

Mental arithmetic - a course in child development (usually 5 to 12 years), which is built on the basis of oral accounts. The course develops mental abilities and as a result, many students have the opportunity to work 2-mA hemispheres of the brain simultaneously.

Normally, all classes is the training using the Japanese soroban accounts (in other words an abacus). At the beginning of the study, each child uses two hands in order to carry out arithmetic operations - moving bone accounts simultaneously stimulated activity, both right and left hemispheres of the brain. Children learn to produce 4 mathematical operations: addition, subtraction, multiplication, and division. At the same the involvement of the two hemispheres of the brain learning any subject becomes most effective.

After this stage of the program, students begin to make the intangible calculation - mental arithmetic. Each of the following exercise cleans up the relationship of the child with the accounts and begins to develop a very active imagination, so in result it will be able to carry out calculations, only introducing the soroban (abacus) as a picture and mentally moving the bones.

Many experts believe that the foundations of modern mathematics was still inherent in the works of such a famous scientist as Euclid. There are a huge number of works in which focuses on all elements of mathematical knowledge, they are the Vedas - the oldest reminder of human culture, the most ancient of all the ancient Greek works for a couple of thousand years. Vedic mathematics, though reduced to the long-known principles, so contains the quality methods for their use, it often seems a miracle. So, the instantaneous multiplication in mind five-digit numbers possible.

For the study of Vedic mathematics need good knowledge of multiplication tables. Those who do not know the table, but would quickly master it, maybe this saddle in many specialized schools or courses.
