A book that thoroughly covers three years of junior high school math in one volume Turns weaknesses into strengths! By Takuya Kosugi, published by Kanki Publishing Unused. I only flipped through it when I bought it at the bookstore. Purchased in April 2023. 1,100 yen (tax included) I spent about an hour at the bookstore looking for an easy-to-understand reference book for a relative's child who dislikes math, and this is the one I chose. I'm selling it because I never had the chance to give it to them. I think this is a very easy-to-understand reference book for children who don't understand the basics of math. It's also perfect for adults who want to relearn junior high school math. Despite having only 127 pages, it explains three years of junior high school math in an easy-to-understand way. The corners of the book are as shown in photos 3-6, but they were in this condition from when it was on the bookstore shelf. Please understand that this has been stored at home before purchasing. There is a possibility that it will be shipped in a recycled box. Thank you for your understanding. *The measuring tape in the photo is not included. #MathReferenceBook #ThreeYearsOfJuniorHighSchoolMath #MathBasics #AdultRelearning
