Hi Christian!  

The abacus is a nifty tool.  Hope you get a chance to 
play with one soon.  You can find some information about the 
abacus on the Web at  

On this page, you'll find information about addition and 
subtraction with an abacus and a bit of its history.

One printed reference I've just heard of is called _Abacus 
Arithmetic_ by Welton Crook, published by Pacific Books, Palo 
Alto, CA.

I haven't had a chance to look at it, but Erez Kaplan, who is 
interested in the history of computing - which includes simple 
"computers" like the abacus - suggested it to me, with the warning 
that REALLY understanding an abacus will take both time and work.  

Good luck and let us know how it goes!
