Product Description
 
Napier’s Bones is an ingenious math material that can multiply and divide very large numbers quickly and accurately. It is, in essence, a calculator. The set includes a series of ten wooden columns, 0 - 9. Below any given number, there are nine squares, each representing the multiples of that number. The tens and units of each multiple, each square are separated by a diagonal line. The strips will represent our multiplicand and the multiplier is along the left-hand side of the frame itself.
