This concise and informative text contains the basic principles of mathematical calculations on the abacus. An event that sparked my interest in abaci and in computers. The user of an abacus is called an abacist. The abacus was in use centuries before the adoption of the written modern numeral system and is still widely used by merchants, traders and clerks in Asia, Africa, and elsewhere. In sand or on tablets of wood, stone, or metal. In Tokyo in 1964 I bought a Soroban with Kojima's book "The Japanese Abacus: Its Use and Theory". Although electronic calculators are replacing it for practical reasons, the use of the abacus continues to be taught in technologically advanced countries such as Japan.
