Abacus 101: Beginner's Abacus & Mental Math: Learn The Story, Concepts & Basics Of Traditional Abacus

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

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.

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.

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

Interesting short book for learning addition and subtraction using a Japanese Abacus with an abundance of exersizes for learning fingering. However, it would be nice to have some instructions and examples for doing multipliation and divison. Also, maybe taking a square root. THe Japanese Mathametition, Dr. O no also used the Abacus to study mathamatical geometry which requires placing an equation on an Abacus for evaluation. It would be nice to at least have references to these advanced techniuqes.

Awesome concept! Looking forward the the next one

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.

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.

This book is an excellent guide for someone that wants to learn how to use Abacus, like me. It doesn't matter what age you are.

This book is ok for a start into using the abacus.
