Who invented the first calculating device?

The first mechanical calculating machine was invented in 1642 by Blaise Pascal, a 19-year-old Frenchman. Pascal’s machine used gears and could add and subtract. Pascal’s gear system was widely used in mechanical calculators built during the next few hundred years.

When was the modern calculator invented?

In 1642, the first true “calculator” was invented: one that performed calculations through a clockwork-type of mechanism. The Pascal calculator, invented by French inventor and mathematician Blaise Pascal, was lauded for attempting arithmetic calculations previously thought impossible.

When did the first calculator come out?
