The abacus is one of the earliest known calculating tools, with its origins dating back to ancient civilizations. It is believed to have been independently developed by multiple cultures, including the Sumerians around 3000 BC, the Egyptians, and the Chinese around 500 BC. While no single inventor can be credited with its creation, the abacus has evolved over time in various regions, reflecting the mathematical needs of those societies.
