New Junior High School Problem Collection, Mathematics Year 2, a塾教材 (juku teaching material). With answers and explanations. This product is not available for purchase in bookstores. I received it from an acquaintance and have kept it at home for several years, so there are scratches, stains, and yellowing on the cover and inside, but I think it can still be used. How about it for review? It's in a test format, and it comes with answers and explanations, so I think it's very easy to work on. How about it for home study during long vacations? Photos ③, ④, ⑤ → Scratches, stains, folds, and yellowing were found on the front and back covers. Photo ⑥ → Scratches, stains, and folds were also found in the answers and explanations. Photos ⑦, ⑧, ⑨, ⑩ → Scratches, stains, and folds were also found inside, and there were a few pages with writing. I have carefully inspected the item and described it as much as possible, but there may be scratches and stains that I couldn't include, or I may have overlooked something. Please understand.
