For a beginner informative

I like this book for the fact that I am trying to learn the abacus on my own for the first time

Basic Abacus- Excellent

Basics to teach a kinder to 2nd grader was easy with this. I did not expect it to go to higher levels. I wish this author had books to address subtraction rules, multiplication and division.

VERY OVERPRICED AND WORTHLESS BOOK!!! [In other words, it's a gyp!]

I agree with aba aba. This book is worthless compared to even the simplest of similar on -line material. Exorbitant price to learn to enter numbers from 0 to 100 and worse than that the organization of the answers to the simple questions requires user to write down manually a table correlating specific test answer with corresponding test numbers and those have to be learned by counting number of tests to that particular one. In addition, the identification as to which is an example and which is a test with corresponding answer is ambiguous.

Interesting Contents.

The abacus secrets , tricks, and concepts that this book introduced is indeed something. It definitely worth the time. It is highly recommended.

Best as a reference after a tutorial video.

There are some illustrations missing from the book. Some grammatical errors. I did not notice a big focus on form and form is important if you plan to springboard into mental math. I think this book would be okay for someone who has already seen a couple of tutorials on youtube or something, but it won't be super helpful as the very first thing you pick up for learning Abacus/Soroban.

This instruction book was produced on too small a budget, so it's not worth buying

The text referred to color in the diagrams, but the book was printed in gray-scale. The instructions are for only one kind of abacus. Whole illustrations are missing, even though the text is formatted for them. The author might be a proficient abacus teacher, but he should never have tried publishing a book on the subject. Save yourself some money on this one.
