The abacus is great for adding columns of numbers and doesn't take long to
learn. While an undergraduate student I used an abacus for a period of time
until a kind soul gave me a calculator.
Leave it on your desk in case your calculator batteries run out - or for a change
of pace. They are great conversation pieces too.
This tutorial primary consists of a set of animated gif files that I created. Use
the left menu to navigate. To rerun an animation click on the menu topic again.
Enjoy! -Dr. Jen
