Napier's Bones was designed in 1617 by John Napier a Scottish Mathematician. In its day it was a wonderous device that simplified complex multiplication and other math processes such as long division and square roots. It was essentially the first calculator and was in common use for nearly 3 centuries.   This is something I find wonderfully elegant in understanding and explaining how basic math works.  This can be a valuable tool for educators.    Plus every math geek should have one to better understand his/her roots:))  Napier's Bones comes with 2 full sets of rods to increase its versatility. The more rods you have, the more complex and varied numbers you can manipulate.  Also includes an attractive base and cover. Made in the USA by Creative Crafthouse.
