#ABACUS HISTORY DRIVER#

The soroban used in CMA’s curriculum, works on a base-10 system and eventually gained popularity over the Chinese abacus. This was later introduced to Japan and Korea and in 1930, the Japanese had it improvised and came up with a 1/4 abacus known as the soroban. Abacus is a Latin word that has its origins in the Greek words abax or abakon (meaning table or tablet) which in turn possibly originated from the Semitic.

#ABACUS HISTORY DRIVER#

The Abacus story began in 1944 when an entrepreneurial street car driver in Baltimore followed a dream to own his own business. The beads were manipulated to perform arithmetic calculations such as addition, subtraction, division, multiplication, and finding square root. Abacus was founded in 1944 in Baltimore and today has a wide network of office locations employing more than 25,000 employees throughout the United States. Much of western mathematics uses a base 10 system (decimal), but geometry and time tracking. These abacuses used a base 60 system (sexagesimal). The latter was seen as the precursor to computer and proved to be an efficient and accurate mathematical calculation tool.Īncient Chinese abacus worked on a 2/5-system which had two beads on the upper deck and five on the lower deck. Abacus originates in Sumeria between 2700-2300 B.C.E. Rather, it was devised by the Babylonians around 300 B.C., while the Chinese abacus we are familiar with today took after the Roman’s grooved abacus and was invented around 1300 A.D. But many believe the origin of the abacus can be detected, a tablet sort of thing was found near the Greek. Early abacuses were intended for counting large numbers and were immobile.Ĭontrary to popular belief, the earliest known calculating board was not a Chinese invention. The specific origin of the abacus is still unknown.

The Greek discovered it on Salamis Island. The first abacus was called Salamis Abacus. The word ‘abacus’ is believed to have originated from the Greek words ‘abax’ and ‘abakon’, which means ‘calculating table or tablet’. History of Abacus- A Greek historian, Herodotus, mentioned that Egyptians were the first to use the abacus.
