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.

The Chinese
The abacus is considered one of the earliest calculating tools, with origins that date back to ancient civilizations. Its invention cannot be attributed to a single individual; rather, it developed over time, with evidence of its use in Mesopotamia around 2400 BC. Various cultures, including the Egyptians, Greeks, and Chinese, adapted the abacus for their own counting and calculation needs. Thus, the abacus is a collective innovation rather than the invention of one person.
