Go to Understanding Napier's Bones at http://www.macs.hw.ac.uk/~greg/calculators/napier/
Click
and read the section "A Great Man."
Click
and read the section "All About Rods."
Run
the Java Simulation.*
*You may have trouble with the demonstration
and simulation on some browsers.
If so, just skip to the next item.
Go to http://mathworld.wolfram.com/NapiersBones.html
Read the information.
Multiply 9 times
739 using the technique shown at this site.
http://users.ju.edu/ssundbe/bones.html
is another site that demonstrates how to multiply using Napier's bones. Which
sites is the easiest to understand? At the time of this publication, the link
to a simulation from this site is incorrect. Is it still?
Go back to http://www.macs.hw.ac.uk/~greg/calculators/napier/
Rerun the Java
simulation, multiplying 39 times 739.
Construct a set
of Napier's bones and use them to multiple 39 times 739.
