The abacus, an ancient counting tool, is believed to have origins dating back to around 3000 BC, although its exact development timeline is difficult to pinpoint. Early versions of counting devices, such as the counting boards used in Mesopotamia, resemble the abacus and may have been used for trade and calculations. However, the more recognizable form of the abacus as we know it today evolved over the centuries in various cultures, including the Chinese, Greeks, and Romans.
