"The Easiest Introduction to Soroban" Kazuyuki Takayanagi Price: ¥1,045 Published: 2021 Purchased new at a bookstore. I read the book at home once after learning about it at school, but I haven't used it since and have kept it at home. There is a small stain, about 1mm, on the top of the book. Please check the last photo. The inside is in very clean condition, with no writing, stains, or tears. The cover has some minor scratches from storage, so I would appreciate it if those who understand home storage would purchase it. There are no pets or smokers. [Content Introduction] Learn while having fun looking at the illustrations! This book explains the soroban, which is now being re-evaluated as an intelligence education tool, in an easy-to-understand way for beginners. From how to use your fingers to multiplication and division, you can have fun practicing how to move the beads while looking at the illustrations. Seibido Publishing
