The Chinese abacus
The abacus is an ancient calculating tool with a history spanning over 3,000 years. Its name derives from the Greek word "abax" or "abakon," meaning "tabular form," possibly originating from the Semitic word "abq," meaning "sand." Evolution of the Abacus Origins (circa 300-500 BC): The exact origin of the abacus is not definitively established, but it is believed to have been invented between 300 and 500 BC. Chinese Abacus (Suanpan): Early versions featured a 2/5 bead configuration, which was complex and later simplified. Japanese Abacus (Soroban): Mathematician Seki Kowa modified the abacus to a 1/4 bead configuration, leading to the modern Soroban used today. Today, the abacus is not only a manual calculator but also a powerful brain development tool. At Mastermind Abacus, we integrate this ancient instrument with modern teaching methodologies to enhance mathematical skills and cognitive abilities in learners.
