Who invented leibnitz's calculator?

Answer 1

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:
