About this site

The site mainly started around the idea of an online generator of exercises to practice the soroban. It evolved a bit with the addition of pages with mental calculation software; then the virtual soroban and its "tutorials" and the possibility to get an operation being displayed on the virtual soroban. A forum was needed to overcome the limitation of disqus, which is a great commenting system anyway.


You don't need a Paypal account if you don't have one

Donations will be used for the possible cost of the site that may arise in the near future with the new pricing policy of Google App Engine. Otherwise, I will take them as a tip for the work I made on this site. We thank any donor in advance of their good gesture.

You may need a currency converter from/to €, you could give a try to the one at xe.com. Beware that Paypal does not use the same exact exchange rate that xe.com
