Mathematics
It is rather difficult for parents themselves to teach well when their children are not good at arithmetic. This book is based not only on the new Courses of Study, but also on the mainstream teaching methods that are currently being taught in schools. Emphasis was placed on the content that is necessary even in junior high school students, and detailed explanations were given on how to think and solve problems with illustrations.
