How to use an Abacus : Hewlett-Packard Calculator : Educalc.net

Basics were very informative, but is it possible to do multiplication and or division? Some of the higher addition techniques were a little bit confusing at times.

This article leaves out one important thing; No make that two things that can make this article great. The first is that it does not tell you that you start calculating numbers on that abacus from right to left. This is obvious to someone that has used that abacus at least once but I came to this site not knowing anything at all about abaci. I had to go to three websites to figure out you go from right to left. In america everything goes from left to right. The second thing: visuals.

What about multiplication and division, or adding and subtracting really big numbers? Is it possible to do things like this on an abacus?

I like your web page very much. I hope you wouldn´t mind my pointing out a fly in the ointment. The abacus shown in the upper left corner of the page displays an incorrect representation of a number. Mathematically there´s nothing wrong with it as far as the abacus is concerned, but it just violates the decimal system of number representation. Furthermore, it can confuses and mislead the novice Chinese abacus user. Thank you.

I know of a very recent book on the basic fundamentals of abacus. I find the book has no competition :)

Do send me a message if you need more info about this book.
