This one has been I’ve enjoy quite a bit. I found a wonderful site…( I love the net…) http://webhome.idirect.com/~totton/abacus/ which teaches just about everything. Even the tradiational exam given to students. Heheh. If anything I think I’ll need a bigger ‘suanpan’( I use a chinese style with two heaven beads and five earth beads). Those cute Asian and their small hands…
But again, its a great tool. Makes math calculations hella spatial,and mechanical.
