Besides addition and subtraction, what two other primary arithmetic functions was the Stepped Reckoner designed to handle?
Answer
Multiplication and division
The Stepped Reckoner represented a significant leap forward because it was conceived to mechanize the complete set of fundamental arithmetic operations. While its predecessor, the Pascaline, was effective only for addition and subtraction, Leibniz engineered his machine to perform all four basic functions. This capability included true multiplication achieved through the stepped drum, and division, which was managed by the architecture performing repeated subtraction facilitated by that same stepping mechanism, making it a comprehensive mechanical calculator for its time.
