Calculators

The Chinese abacus was developed about 5000 years ago. It was built out of wood and beads. It could be held and carried around easily. The abacus does not actually do the computing, as today\'s calculators do. It helps people keep track of numbers as they do the computing. However today we try and make it easier by supplying a calculator tailored for your needs, basic or scientific.
