Pascal's calculator, also known as the Pascaline, is an early mechanical calculator invented by the French mathematician Blaise Pascal in the 17th century, specifically in 1642. Designed to help his father with tax computations, the Pascaline was one of the first devices capable of performing addition and subtraction directly, and it laid the groundwork for the development of more advanced calculating machines.
