This is a math problem book for the new school year, covering a wide range of topics from basic to advanced. I received it in class in the 6th grade (two years ago), but I haven't used it. It can be used to review elementary school arithmetic and Japanese. You can review calculations, decimals, fractions, geometry, etc. - Title: New School Year Preparation Course - Publisher: Try Plus - Content: Math problem book - Language: Japanese Thank you for looking. I hope someone will find it useful.
