In 1642 Blaise Pascal (a famous French mathematician) invented an adding machine based on mechanical gears in which numbers were represented by the cogs on the wheels.
The abacus or counting frame was a device used for calculations that is probably 5000 years old and is still used throughout Asia and Africa.
The introduction of the 1st mechanical calculator was invented in Europe. This type of calculator production then spread world wide. The first ever was invented by Willhelm Schickard.
