Napier's bones are a set of mathematical tools invented by the Scottish mathematician John Napier in the early 17th century, specifically for the purpose of performing multiplication and division. They consist of a series of rods inscribed with numbers, arranged in a way that allows users to carry out calculations more easily than with traditional arithmetic methods. Each rod represents a digit and is divided into sections that show the products of that digit multiplied by numbers from 0 to 9.
