Napier's bones, used for calculating products and quotients of numbers was also called Rabdology. Napier first published his method in 1617.
Napier's bones is a manually operated calculating device created by John Napier of Merchiston, Scotland for the calculation of products and quotients of numbers. The method was based on lattice multiplication, and also called rabdology, a word invented by Napier. Napier published his version in 1617.
Because he wanted a simple calculating device. (It's "bones" actually.)
The advantages of the Napier's bones, a manually-operated calculating device invented by John Napier in the 17th century, include its ability to perform multiplication and division quickly and accurately. It also allows for easy manipulation of numbers through the use of movable rods. However, the disadvantages of Napier's bones include its limited capacity for complex calculations and the potential for human error in setting up the rods correctly.
