The word abacus has been derived from Latin word abax and abakon (meaning table or tablet) which in turn possibly originated from the Semitic word abq meaning “sand.”
The Chinese abacus was developed about 5000 years ago. The traditional abacus is built out of beads and woods. The popularity of abacus has spread from China to many other countries. The abacus is not a calculator; it helps people to keep track from numbers while computing it.
