Answer:
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 in Rabdologiæ,[1] printed in Edinburgh, dedicated to his patron Alexander Seton.
