They were able to convert the process of multiplication (or division) to addition (subtraction). This allowed large amounts of work to be delegated to clerical staff who were competent at adding and subtracting and a lot cheaper than people who could multiply and divide efficiently.

The Napier's bones, also known as Napier's rods, were a calculating device used for multiplication and division in the 17th century. They consist of a set of numbered rods, each representing a digit from 0 to 9. By aligning the rods and performing a series of additions and subtractions, complex calculations could be carried out quickly and accurately. This mechanical tool was a precursor to modern-day multiplication and division methods, such as the multiplication table and long division algorithm.
Napier's bones are a manual calculation device created by John Napier for simplifying multiplication and division. They consist of a set of numbered rods or strips that can be used to perform calculations quickly and accurately. Each rod represents a different digit, and by aligning the rods in a specific way, complex calculations can be completed efficiently.
