Gottfried Leibniz worked on perfecting the Pascal adding machine and attempted to improve it so that it would be able to multiply and divide by achieving this goal through the placement of a mechanical device called the Leibniz cylinder.
After having perfected this machine, Leibniz focused his efforts on creating a method that would allow the decimal system to be converted into a binary-based system.
Pascaline was invented by Blaise Pascal in It was the son of a civil servant whose job was to collect taxes.
Pascal, who occasionally helped his father to write his official reports, wondered how to help his father in the different arithmetic operations in which large numbers had to be added.
Pascaline had the shape of a shoe box and was low and somewhat elongated. On the inside, there were a series of sprockets that were connected to each other, thus forming a transmission chain , so that when a wheel turned completely on its axle, it advanced one degree to the next.
These different wheels that were inside the Pascaline had as function to represent the decimal system of numeration. Each wheel consisted of ten steps, so it was also marked with numbers ranging from 9 to 0.
It feels like an addition since the only two differences in between an addition and a subtraction are the position of the display bar direct versus complement and the way the first number is entered direct versus complement.
Pascalines came in both decimal and non-decimal varieties, both of which can be viewed in museums today.
They were designed for use by scientists, accountants and surveyors. The simplest Pascaline had five dials; later variants had up to ten dials.
The contemporary French currency system used livres , sols and deniers with 20 sols to a livre and 12 deniers to a sol.
Length was measured in toises , pieds , pouces and lignes with 6 pieds to a toise , 12 pouces to a pied and 12 lignes to a pouce.
Therefore, the pascaline needed wheels in base 6, 10, 12 and Non-decimal wheels were always located before the decimal part.
In an accounting machine.. In a surveyor's machine.. Scientific machines just had decimal wheels. The metric system was adopted in France on December 10, , by which time Pascal's basic design had inspired other craftsmen, although with a similar lack of commercial success.
Most of the machines that have survived the centuries are of the accounting type. Seven of them are in European museums, one belongs to the IBM corporation and one is in private hands.
In , Franz Hammer, a biographer of Johannes Kepler , announced the discovery of two letters that Wilhelm Schickard had written to his friend Johannes Kepler in and which contain the drawings of a previously unknown working calculating clock, predating Pascal's work by twenty years.
Bruno von Freytag Loringhoff, a mathematics professor at the University of Tübingen built the first replica of Schickard's machine but not without adding wheels and springs to finish the design.
A problem in the operation of the Schickard machine, based on the surviving notes, was found after the replicas were built.
Each digit used a display wheel, an input wheel and an intermediate wheel. During a carry transfer all these wheels meshed with the wheels of the digit receiving the carry.
The cumulative friction and inertia of all these wheels could " Pascal chose, for his machine, a method of re-zeroing that propagates a carry right through the machine.
This could be taken as a testament to the quality of the Pascaline because none of the 18th century criticisms of the machine mentioned a problem with the carry mechanism and yet this feature was fully tested on all the machines, by their resets, all the time.
Gottfried Leibniz started to work on his own calculator after Pascal's death. He first tried to build a machine that could multiply automatically while sitting on top of the Pascaline, assuming wrongly that all the dials on Pascal's calculator could be operated at the same time.
Even though this could not be done, it was the first time that a pinwheel was described and used in the drawing of a calculator.
He then devised a competing design, the Stepped Reckoner which was meant to perform additions, subtractions and multiplications automatically and division under operator control.
Leibniz struggled for forty years to perfect this design and produced two machines, one in and one in The German calculating-machine inventor Arthur Burkhardt was asked to attempt to put Leibniz' machine in operating condition.
His report was favorable except for the sequence in the carry. He was also the first to have cursors to inscribe the first operand and a movable carriage for results.
Around Claude Perrault designed an abaque rhabdologique that is often mistaken for a mechanical calculator because it has a carry mechanism in between the numbers.
But it is actually an abacus, since it requires the operator to handle the machine differently when a carry transfer takes place.
Pascal's calculator was the most successful mechanical calculator developed in the 17th century for the addition and subtraction of large numbers.
The stepped reckoner had a problem in the carry mechanism after more than two consecutive carries, and the other devices had carry mechanisms one tooth wheel that were limited in their capacity to carry across multiple digits or had no carry mechanism in between the digits of the accumulator.
Calculating machines did not become commercially viable until , when Thomas de Colmar released, after thirty years of development, his simplified arithmometer , the first machine strong enough to be used daily in an office environment.
The Arithmometer was designed around Leibniz wheels and initially used Pascal's 9's complement method for subtractions.
