Hi there i was wondering
if you would have any information on "counting on your fingers" or " Chisabop".
Im doing a project and would be happy to have this informaltion.
I did a search using Google and found a Chisenbop
tutorial that looks helpful. Also in the Quandaries and Queries
database is an explanation by Patrick Maidorn of multiplication by
9 using Chisenbop.
