Detailed explanation-1: -Step Reckoner, a calculating machine designed (1671) and built (1673) by the German mathematician-philosopher Gottfried Wilhelm von Leibniz. The Step Reckoner expanded on the French mathematician-philosopher Blaise Pascal ’s ideas and did multiplication by repeated addition and shifting.

Detailed explanation-2: -Modern replica of the Staffelwalze, or Stepped Reckoner, a digital calculating machine invented by Gottfried Wilhelm Leibniz around 1672 and built around 1700, on display in the Technische Sammlungen museum in Dresden, Germany.

Detailed explanation-3: -The stepped reckoner or Leibniz calculator was a mechanical calculator invented by the German mathematician Gottfried Wilhelm Leibniz around 1672 and completed in 1694. The name comes from the translation of the German term for its operating mechanism, Staffelwalze, meaning “stepped drum".

Detailed explanation-4: -Invented by Leibniz in 1673, it was used for three centuries until the advent of the electronic calculator in the mid-1970s. Leibniz built a machine called the stepped reckoner based on the design of the stepped drum in 1694.

Detailed explanation-5: -1673-Gottfried Wilhelm von Leibniz (1646-1716) He invented a calculating machine known as Leibniz’s Wheel or the Step Reckoner. It could add and subtract, like Pascal’s machine, but it could also multiply and divide.
