Features of this book

· Textbooks linked to the basic concept book "The Fountain of Mathematics" and the basic problem book "Hi Math"
- This is a textbook that allows you to practice higher-level problems based on the concepts and problems you have learned in the basic concept book “The Fountain of Mathematics” and the basic problem book “Hi Math.”
Since the unit structure and order are the same, you can study it in conjunction with “The Fountain of Mathematics” and “Hi Math.”

· A basic problem book that can help you reach the highest level of mathematical skills.
- This textbook is for students who want to improve their math skills by solving difficult problems.
Starting with questions that often appear on school exams, you can practice in-depth questions and even practice advanced problems at the highest level.

· A basic problem book that allows sufficient practice of discriminatory problems
- This textbook is composed of [basic problems that the teacher always gives] + [internal grade type problems] + [first-grade problems] + [highest difficulty problems].
In particular, in the [First-Class Problems] and [Highest Difficulty Problems] corners, you can sufficiently practice problems that require high mathematical thinking skills.

· A textbook that ensures top grades in internal exams and mock exams
- We have analyzed and classified the types of difficult questions that appear in school exams and mock tests, and included them.
We have included plenty of high-level discrimination questions to help you prepare thoroughly for high-scoring internal exams and mock exams.

Structure of this book

· Concept organization
- The important concepts and formulas of each unit are organized so that you can see them at a glance.
We've added useful formulas and concepts, as well as problem-solving tips that will directly help you solve problems, to Concept Plus.

· Basic problems that teachers always ask
- We have selected basic types of problems that appear frequently in each unit and must be solved.
You can solve representative problems that the teacher emphasizes and teaches.

· Internal exam type problem
- To improve mathematical thinking skills, problem types are presented in an integrated manner and more in-depth problem practice is possible.
Questions that you absolutely must solve and remember are marked as 'Important'.

· First-class problems
- We have selected and included discriminating questions that can determine a grade 1 on the exam.
We have provided a variety of practice problems that can improve mathematical thinking and application skills.
In particular, we have made it possible to solve even the 'highest difficulty problems'.
