in If You Don’t Know How to Use an Abacus You Can Learn Here on Zaphu Forum
Thanks for the info, Riley! We bought our abacus to deal with a very unique Maths issue and with your help our Ordeal is over.

However, our abacus is different to any we've seen so far. It has 15 columns with only one altobead but 5 hypobeads apiece.

The configuration is very handy and easily utilised thanks to your Guide.

We like it so much we are considering consolidating a collection of abaci ourselves.

Thanks again for your info.
