Explanation: 

Detailed explanation-1: -Leibniz Calculating MachineIn 1671 Gottfried Wilhelm von Leibniz (1646-1716) invented a calculating machine which was a major advance in mechanical calculating.

Detailed explanation-2: -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-3: -Gottfried Leibniz was a German mathematician who developed the present day notation for the differential and integral calculus though he never thought of the derivative as a limit. His philosophy is also important and he invented an early calculating machine.

Detailed explanation-4: -It can be used in the calculating engine of a class of mechanical calculators. The stepped drums can be twisted with a crank of different sizes which is around 0 to 9 sprockets. The numbers moving and Depending on their direction of movement, these numbers can be added or subtracted.

Detailed explanation-5: -Gottfried Leibniz’s major contribution to mathematics was his discovery of the binary numeral system, or the base-2 system, which we find today in computers and related devices. The binary numeral system is a way of writing numbers using only two digits: 0 and 1.
