Textbook guide for Tokyo Shoseki's Shinpen Atarashii Suugaku (New Mathematics) for junior high school students, 1st year. Useful for improving scores on regular tests. Explains how to solve problems, provides answers, and clarifies the content of lessons. This is a used item, so there may be some scratches and stains, but there are no markings, so I think it can still be used. (There is a possibility of oversight) I will sell it to someone who doesn't mind the details.
