    UCMAS Mental Arithmetic

    An arithmetic calculation performed by using the brain without the help of any gadget like Paper, pencil, calculator or computer is known as mental arithmetic. In U C MAS, Mental Arithmetic is a method of mental calculation; performed on a virtual image of an abacus, formed in the mind.

    It is based on the principles of abacus calculation. Initially, the child takes the help of the abacus in the calculation, over a period of regular training & practice they would be able to visualize and internalize the image of the abacus in their mind and master any arithmetic calculation within a few seconds without relying on any gadgets or even the Abacus.


    Many people often assume that learning mental arithmetic is merely a method to improve the speed and accuracy of calculations, for example, adding 10-digit numbers within a few seconds. By itself, it is already an amazing accomplishment for most young children. However, there is more to this because when the children are learning U C MAS Mental Arithmetic, they are actually also undergoing the process developing other aspects of the mind. When the children have acquired an astonishing calculation speed, it is actually only the end result of having developed the following mental abilities: concentration, observation, visualization & imagination, and memory.


    Concentration is the concentrated and directed attention towards a particular matter with the clear reflection that creates a deep image and mental impression. An enhanced concentration leads to better absorption power. Studying will then be a joyful thing for these children. In the abacus and mental arithmetic education children will be trained to concentrate when listening to the teacher’s questions (that ranges from easy to difficult) and then focus on calculating the answers as accurately as possible.


    Observation is the ability to compare and analyze and differentiate objects, motives, and steps. It is also a state of alertness and swiftness of the mind and senses. This comes from the need to understand the theoretical requirements of each calculation and at the same time be aware of the time, and promptings from the teachers.


    By using the imagination of the right brain to visualize the abacus in mind, inevitably the powers of visualization would become sharp and clear. Albert Einstein believes that the imagination is important than knowledge because imagination is the main source of yet-to-be-discovered knowledge.


    Memory is the ability to store and retrieve information and experiences. It has been found that memory in the left-brain would not stay long, but an image that is recorded in the right brain would stay on in the mind forever. By stimulating the right brain with mental arithmetic, and in combination with the alertness of the eyes, ears, and hands, the ability to store and recall is developed together. Therefore, the ability to solve 10-digits arithmetic problems in only a few seconds is only a small success in comparison to the actual mental training that has been done in order to achieve the skill to perform rapid calculations.
