Pascaline (also known as the arithmetic machine or Pascal's calculator) is a mechanical calculator invented by Blaise Pascal in 1642. Pascal was led to develop a calculator by the laborious arithmetical calculations required by his father's work as the supervisor of taxes in Rouen , France. [ 2 ]
Two decades after Schickard's supposedly failed attempt, in 1642, Blaise Pascal decisively solved these particular problems with his invention of the mechanical calculator. [3] Co-opted into his father's labour as tax collector in Rouen, Pascal designed the calculator to help in the large amount of tedious arithmetic required; [ 4 ] it was ...

Blaise Pascal and Wilhelm Schickard were the two original inventors of the mechanical calculator in 1642. [1] For Pascal, this was an adding machine that could perform additions and subtractions directly and multiplication and divisions by repetitions, while Schickard's machine, invented several decades earlier, was less functionally efficient ...

The Renaissance saw the invention of the mechanical calculator by Wilhelm Schickard in 1623, [9] and later by Blaise Pascal in 1642. [10] A device that was at times somewhat over-promoted as being able to perform all four arithmetic operations with minimal human intervention. [11]
