An abacus is a counting device that uses beads on a table or string that represent numbers. The device is divided into columns, each column representing a multiple of 10 (x10, x100, x1000 etc.) and each column has 10 beads in it. This enables numbers to be formed by rearranging the beads, this means that simple and complex arithmetic can be performed on the abacus.The abacus was invented around 2,700-2,300 BCE, by the Sumerians (Mesopotamia) ; that makes the invention about 4,400 years old. This is the oldest dated abacus, there are several versions between 2,700 - 1,000 BCE, with many groups claiming responsibility for the invention.The earliest know Chinese abacus, called the Saunpan (translated as Counting tray) is only dated to about 200 BCE.

The Chinese abacus was developed about 5000 years ago. It was built out of wood and beads. It could be held and carried around easily. The abacus was so successful that its use spread form China to many other countries. The abacus does not actually do the computing, as today's calculators do. It helps people keep track of numbers as they do the computing.

Yes, it was an early mechanical computer. It is regarded as the first computer, made over 5000 years ago. An abacus is not like a modern computer. People think of a computer as an electronic, programmable device that can store, retrieve, and process data. There were many computing devices prior to the electronic computer that had processing capabilities. They were mechanical devices and are computers. There are many different kinds of computing devices and an abacus is one of them.

The abacus is ordinarily attributed to the Chinese, but similar counting devices are known in many different ancient cultures. The system of mathematics used with the Indo-Asian abacus is what set it apart.
