Computers are a modern invention, right?
The first computer was the abacus, which was invented around 5,000 years ago.
The abacus consists of a frame with wires and beads, and acts as a calculator.
As late as 1980, over 2 million of these were sold per year in Japan.
A proficient abacus operator can calculate as quickly as someone using an electronic calculator.
Areas of the Far East still use the abacus to conduct business today.
Contrary to popular belief, the abacus was not invented in China.
Evidence suggests it was first used in Egypt.
