Review Book "Mathematics for Junior High School"

Viewed in terms of Information

Mathematics for Junior High School which is arranged by Mr. Marsigit is a useful book. We can get more information in each chapter of this book. The way to inform reader especially for student of junior high school is use the language that is communicative and easier to understand.
Each chapter is explained in detail that is by sub chapter. It is presented in bilingual language, they are Indonesian and English language. So the student can improve their Mathematics English words and vocabulary. Each sub chapter explained theoretically, given example exercises, and exercises. Of course, we not only get information about the subject from each chapter but also get other information in the form of pictures and exercises.

The explanation of the subject from each chapter is clear and solid. Besides them, there are attractive thing that is also useful. They are a box images which contain of remember things. It can help readers to understand and learn the subject. There also information about what subject will be discussed in that chapter in front of chapter. For the example:
What will you learn in this chapter?
 The Relations
 The functions
 The value of function
I sure that this book is very good and very useful to read or learn, but there are some lacks that I think if it is improved some parts in this book, it will be prefect. Some lacks are:
1. There are not answers key of the exercises.
2. Hasn’t summary in each chapter.
3. The information about biography of author is hasn’t.
I think that’s all my review book which is entitled “Mathematics for Junior High School”. I support this book because I’m sure that this book is looked for many people and student especially for student of junior high school.
