Lettre dédicatoire à Monseigneur le Chancelier, sur le sujet de la Machine novellement inventee par le Sieur B. P. pour faire toute sortes d'operations d'Arithmetique, par un movement regle, sans plume ny jettons.
The Pascaline 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. He designed the machine to add and subtract two numbers and to perform multiplication and division through repeated addition or subtraction. It used a stylus to perform calculations.
