Napier's Bones (The old calculator | Multiplication & Division)

𝐍𝐚𝐩𝐢𝐞𝐫'𝐬 𝐁𝐨𝐧𝐞𝐬 John Napier was a Scottish scientist, born in the 16th century, who spent much of his time inventing ways to make calculations easier. He’s best remembered for developing methods so that multiplication and division can be carried out using the simpler operations of addition and subtraction. Napier developed logarithms in 1614 and a device called Napier’s bones in 1617. Both these methods became commonly used in science and commerce.
