the fact that it worked, and people liked it
Blaise Pascal and Wilhelm Schickard one of those
Leibnizs calculator is simply an improsive version of the adding machine.This machine could perform multiplication and division as well.Talking about the history of a machine it was invented by a German mathematician Gottifried
The adding machine is actually a calculator. but in the mid 1642's it was called an adding machine. it was used to help with mathimatics
leibnitz's calculator is simply an improvised version of the adding machine. this machine could perform multiplication and division as well. ( multiplication through repeated addition and division through repeated subtraction). talking about the history of this machine it was invented by a German mathematician Gottfried Leibnitz. It used a stepped cylinder with nine teeth for varying lengths instead of wheels used by pascal. For a better idea refer to a picture of Leibnitz's calculator: http://images.Google.co.in/images?hl=en&q=leibnitz%27s+calculator&btnG=Search+Images&gbv=2&aq=f&oq= (please press ctrl and then click on the above link to view the picture.) tell me if the link does not work.
An adding machine is a mechanical or electromechanical calculator which could perform addition and subtraction.
The first adding calculator machine was invented by Blaise Pascal.
Possibly the abacus, a board with wood rods, and wood beads on the rods. It is thousands of years old. The first electronic computer, I think, was Univac. It used vacuum tubes instead of solid state devices to do its computing.

It was Blaise Pascal that invented the adding machine in 1642. He invented this machine to help ease the burdens of his father who worked as a clerk at the time.
