Detailed explanation-1: -The arithmometer, invented by Charles Xavier Thomas de Colmar in 1820, was the first commercially successful calculating machine capable of performing addition, subtraction, multiplication and division.
Detailed explanation-2: -The arithmometer was capable of multiplication, three-digit inputs, and six-digit results. Also known as the Thomas machine or Thomas arithmometer, the device was built upon to create the Saxonia, Peerless, and other historic mechanical calculator inventions.
Detailed explanation-3: -The computing engine of an arithmometer has a set of linked Leibniz wheels coupled to a crank handle. Each turn of the crank handle rotates all the Leibniz wheels by one full turn. The input sliders move counting wheels up and down the Leibniz wheels, which are themselves linked by a carry mechanism.
