it help to do large number of multiplication and divison
Napier's Bones, a system similar to an abacus which assists in the calculation of products and quotients, and also referred to as Rabdology, was first mentioned as a new invention by Napier in 1617 in Edinburgh, Scotland.
Bones
John Napier (1550 - 4 April 1617) was a Scottish mathematician, physicist, astronomer, and astrologer. He is known as the inventor of logarithms, Napier's bones, and made using the decimal point popular.
Because he wanted a simple calculating device. (It's "bones" actually.)
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.

logarithmic device called as napier bones
To have a type of abacus to use.
in 1614 john Napier invented logarithms and a device called NAPIER,s bones
Napier's Bones is a quick and easy way of doing multiplications, invented by John Napier in the 17th Century.
Napier's Bones, a system similar to an abacus which assists in the calculation of products and quotients, and also referred to as Rabdology, was first mentioned as a new invention by Napier in 1617 in Edinburgh, Scotland.
John Napier's calculating machine invention is called "Napier's Bones."

Napier's bones, used for calculating products and quotients of numbers was also called Rabdology. Napier first published his method in 1617.
