Abacus
is an ancient instrument which was discovered 2500 years ago, and was used for
doing mental arithmetic calculations. The instrument was made of frames (wood
etc.) which had beads made of sand, stones, pebbles etc. It made use of both
the hands to move beads and perform calculations. This process enables the use
of both left and right sides of brain through proper finger movements.
Evolution of Abacus
There
have been contradictions on “who discovered Abacus?” It is believed that the
Abacus instrument was discovered in China in 500 B.C. while some arguments
indicate it was discovered by Babylonian circa in 300 B.C. According to some
sources, Abacus was first used by Indians with a separate column for ‘shunya’
also known as ‘zero’.
The
most primitive Abacus was the Salamis tablet used by Babylonians. All the
evolutions in size, shape or appearance were done based on this Abacus. The
Chinese Abacus, named Suanpan, which existed in modern age, was the one having
2/5 decks. The Japanese Abacus, Soroban soon replaced Suanpan due to its
complexity in operations. Soroban Abacus had 1/4 decks and is the one which is in
use today.
Functions of Abacus
The
Abacus is used for calculating operations like
addition, subtraction, multiplication, division, decimals and calculations for
negative numbers.
