The earliest calculating devices include the abacus, which dates back to ancient times and was used by various civilizations, including the Sumerians and Egyptians. Another early device is the tally stick, used for counting and record-keeping. The Antikythera mechanism, an ancient Greek analog computer from around 150-100 BCE, is also notable for its complex gears and ability to predict astronomical positions. These devices laid the groundwork for the development of more sophisticated calculating tools throughout history.
