2.  Introducing

One of the most profitable activities is to learn, because learning we can learn the rest of God's creation. Either learn by anyone, anywhere, and with any sources.

“Get over the idea that only children should spend their time in study. Be a student so long as you still have something to learn, and this will mean all your life.”

–Henry L. Doherty

3.    Description of The Contents  

Mathematics. Mathematics is the basis of all good science, to be studied and applied in daily life. Mathematics is indispensable in the life of every aspec. It is not wrong if the mathematics is called the parent of all the sciences.

Learning mathematics is easy if our sense of curiosity is high. Learning math is easy if we want. With the book " MATHEMATICS 2 FOR JUNIOR HIGH SCHOOL YEAR VIII" allows us to study. In this book contains seven chapters. The material in Chapter 1 is about Algebra and Its Applications. We discussed  three aspects. The three aspects of it are The Algebraic Expressions, The Algebraic Factorizations, The Fractions Operation of Algebraic. The material in Chapter 2 is about The Relation and Functions. In there, discussed three aspecs. They are The Relations, The Functions, The Value of Function. The material in Chapter 3 is about The Equations of The Straight Line. In there, discussed three aspecs. They are The Characteristic of The A Straight Line’s Equation, The Gradient, Line’s Equations. The material in Chapter 4 is about The System of Linear Equations in Two Variable. In there, discussed three aspecs. They are The Linear Equations in One Variable (LEOV), The Linear Equations in Two Variable (LETV), and The System of Linear Equations in Two Variable (SLETV). In chapters one through four is included in unit 1. While unit 2 there are 3 chapters. The material in Chapter 5 is about The Pythagorean Theorem. In there, discussed five aspecs. They are The Pythagorean Theorem, The Length of The Sides of A Right Angle Triangle, The Length of The Sides of Any Triangles, The Ratio Sides of Some Special Right Triangles, The Pythagorean Theorem in Daily Life. . The material in Chapter 6 is about  A Circle. In there, discussed four aspecs. They are Introducing A Circle and Its Parts, Te Central Angles and The Circumference Angles, The Tangents of The A Circle, The Inscribed an Circumvented Triangles of A Circle. And the last Chapter is Polyhedral. In there, discussed four aspecs. They are Prisms, Cubes, The Rectangular Prisms, and The Pyramids. On each chapter comes with sample questions, and practice questions.

4.  The Advantages of Book

Seen from the cover of the book, this book is very interesting to read. The cover of interest, increasingly make students to learn them. In addition, when viewed from inside. Content that uses two languages, English and Indonesian create comfort in reading. In addition to getting the material about mathematics, we also learn the language of mathematics itself, due to English being the language of the world. This book comes with sample questions and practice questions, so that the reader can train of logic to solve problems of mathematics. The book also comes with colored pictures and content with a good quality paper. It will not make readers feel bored to read and study it.

5.  The Lack Of Books

To facilitate students in understanding and also adds a sense of curiosity they, in practice problems needed the answer keys. The point of the answer keys were not solely so that children know the answers instantly without work, but needed answers to the exercise the students can be justified by what they have learned in the book. And make it easy for students to achieve the overall material with confidence.

6.  Conclusion

This book facilitate us to learn mathematics by using two languages and this will make us learn properly. This book is intended for the students classes VII junior high school, but this book is suitable for all ages studied. This book has been arranged neatly. Mathematics can be studied and understood easily by using the book "MATHEMATICS 2 FOR JUNIOR HIGH SCHOOL YEAR VIII". With this book we can deepen the mathematics with the various chapters that explained.
