Mental Abacus 4+

After having graduated many years ago, I decided to learn to use an abacus as a precursor to delving back into math. I’ve read a couple of books on using an abacus (e.g., “The Japanese Abacus”) but never felt like I understood what they were saying. This tutorial is well written (although several grammatical errors make it clear that it was translated) and provides a great explanation of using the abacus. I finally understand what the other books I read were trying to say but were unable to do in as clear a fashion as this tutorial. I’m also a bit leery about the two-hand method but I’m definitely going to give it a try. I only have two minor annoyances. First, I wish the Abaculator had the option of allowing the user to manually step through the explanation with a “next step” button rather than having to pause and continue the explanation. This, however, is a minor point. Also, it would be nice to have the “Abacus Trainer” functionality (I.e, practice problems) in the app rather than being a separate app. Nevertheless, I’m happy to finally have found an abacus tutorial that I understand.

Thank you very much for your valuable comment. We are very sorry for any grammatical errors in our presentation, please do let us know.

Mental Abacus series act as interactive self-learning eBooks with intensively illustrated examples and demonstrations, while Abacus Trainer series provide different type of exercises with customised techniques, specific aspects and levels.

Thank you so much for your suggestion, it will certainly help us improve our apps in the future. Thank you for your support.

My daughter is in level 2. I bought this app as a summer training course. We kept on reading, there is no games, that makes it really boring. Very disappointing....

We are very sorry for your disappointment.
