[This book's structure and usage]
01 This is the optimal self-directed learning book for complete conceptual learning. The foundation of mathematics learning is a complete understanding of concepts.
We have divided the units into sub-units that form the basis of the concepts, and explained them so that the basic concepts can be clearly understood.
We have made it possible to establish clear concepts by focusing on explanations of [the summary of the formula], [the principle of formula creation], [tips from senior learners], and [common errors] when solving problems.


02.
This book is designed to help you achieve the best learning outcomes with optimal problems.
1. EXAMPLE & APPLICATION The most appropriate [EXAMPLE] is provided to help you apply the concepts studied in the sub-unit.
We've ensured a solid understanding of the concepts through various approaches and additional explanations. We've also provided application sections to solidify the concepts by allowing students to apply and apply the methods learned in the examples.
2.
Basic & Advanced Examples
With a solid foundation of concepts, you can learn the types of problems in each unit of mathematics.
Representative types of problems are divided into [Basic Examples] and [Development Examples], and the solutions are shown along with the solution guide. Also, [Problem] problems of the same type are presented so that you can practice the corresponding type perfectly.
Additionally, [Summa's advice] provides supplementary explanations to help you thoroughly prepare for the relevant question type by highlighting common mistakes and adding important additional explanations.
3.
Review Quiz by Intermediate Level
We have divided the important concepts studied into small units and presented them in parentheses, true/false questions, and simple explanation questions by unit.
This helps you maintain a holistic perspective by recapitulating important concepts for each lesson.
4.
EXERCISES by unit and unit
We have tested the concepts and types of problems that have already been learned by unit and unit.
The questions are arranged into A and B levels [by difficulty], and they are comprised of questions that can appear on both internal and external exams, allowing you to accurately assess your skills. Using EXERCISES, you can identify areas of weakness and receive feedback through concept study, allowing you to more thoroughly grasp key concepts.

03.
You can expand your thinking with Advanced Lecture/MATH for ESSAY.
1.
Advanced Lecture (Advanced, Linked Learning)
It presents content that is more in-depth than the main text and is linked to higher-level learning that will follow.
In particular, we have explained the material at a level that students can fully understand, so that they can improve their math skills through in-depth learning.
2. MATH for ESSAY
We have presented learning materials related to mathematical reasoning and oral presentations that can be studied in conjunction with the second-year high school level.
In addition to the advanced and linked learning mentioned above, we have prepared a course for students who wish to learn more advanced mathematics, including in-depth study of mathematical principles and preparation for [mathematical reasoning and oral presentation], which are emphasized in the entrance exam.

04.
You can develop a sense of real-world experience by taking practice tests to prepare for internal and mock exams. In math, developing adaptability through exposure to numerous problems is one of the most important study methods, along with understanding the principles.
To this end, we are providing additional excellent problems for each unit through [Test for Internal and Mock Exams].
You can measure your skills by unit or develop a sense of reality by preparing for midterm and final exams and various mock exams.

05.
Self-study is possible with easy and detailed explanations.
A good explanation for each problem is as essential to improving your skills as the problem itself.
We have presented the most appropriate and easiest solution to the problem, and have also provided additional solution methods that would be helpful to know, making it a good textbook for self-study.
