China Answer: The abacus has a history going back to 2500 BCE when it was first used in Sumeria.Later and improved versions were in use in Babylonia, Egypt, Persia, India, China, Rome and Greece. There are reports of abaci in India as early as the 1st century CE. The first use of Chinese abacus is not documented until the 14th Century CE although there is evidence in Chinese illustrations that they were in common use as early as 1100 CE. It was similar to the modern abacus. From China the abacus spread into Japan and Korea.Some scholars point to an independent development of the abacus in Mesoamerica by the Mayans and Aztecs. These were of course based on the base 20 not 10 as in Asia and Europe.
The abacus is considered the first adding machine because it was the first tool that was used to add with. There were not any counting devices until the invention of the abacus in 3000 BC.
