Yasashii Koukou Suugaku (Easy High School Math) Suugaku 1・A Revised Edition By Hiroshi Kisaragi Gakken Educational Publishing This is a textbook that starts with a review of junior high school material and explains the concepts very clearly. I think it's the perfect textbook for current high school students as well as those who want to relearn the material. There is some minor scuffing, but the pages are clean with no folds, tears, stains, or discoloration. There are no writings or underlines. Please check the photos for the condition. You can buy it immediately without commenting beforehand. We will cover the shipping costs (anonymous shipping).
