→ A textbook that provides ample practice in writing descriptive solutions in the example + problem section, with strengthened proofs in the concept section.
· Problems necessary for learning concepts are provided based on analysis of the latest past exam questions.
A versatile textbook presented in a practical style that can even help you prepare for internal exams.

Visually grasp key content at a glance

· A textbook that highlights important content so that students can grasp it visually.
· In both concept organization and examples, the key points that need to be remembered are presented at the very beginning.
· A textbook that allows students who have difficulty reading long texts to immediately understand what they need to know.

[A concept summary that allows you to solidly learn all advanced math concepts without missing anything]

“The concept section was organized in a way that was easy to see and read, and we focused on making sure that there was no missing content to help you understand the concept.
In addition, if there is anything you need to know when solving real-world problems, we have included those parts in the concept organization section to organize them into practical concepts.”

[A set of core concepts and examples to learn from examples & a sufficient number of examples]

“We put a lot of effort into differentiating the examples and problem-solving sections, which are the core of the concept book and take up the largest portion, from existing textbooks.
The practical concept keywords presented before the questions help you grasp the core concepts, serve as hints, and help you reinforce your memory of important content.
Even in the example solutions, we highlight key points so you can see at a glance the parts you shouldn't miss when writing a descriptive solution.
We provide more detailed explanations than other textbooks so that even students studying alone can easily understand.
“The problem-solving corner where learners must solve problems is fixed to the right page of the book, and the margins are generously arranged in two columns for ease of use.”

[Special lectures that broaden and deepen mathematical understanding]

“We cover content that is not covered in the curriculum but will help you understand the concepts and make problem solving easier. We also provide practice problems when necessary.”

[Completely master and apply the concepts of each unit through step-by-step practice problems]

“It is structured so that you can check what you have learned through basic problems in the first stage, apply what you have learned through practical problems in the second stage, and develop problem-solving skills through difficult problems in the third stage.
The problem numbers for each step are colored yellow, blue, and green, making them easy to distinguish at a glance and convenient to use selectively as needed.
“With practice problems filled with the latest issues, you can thoroughly learn the concepts and lay the foundation for achieving a top grade in your final exam.”

[Friendly answers and explanations]

“You can collect and present answers in the quick answer section at the back of the book, making it easier to grade the problems you solve.
The numbering of the problems throughout the textbook makes it easy to find the correct answer.
“In the separate Answer Key and Explanation section, we provide detailed solutions to incorrect answers so that you can solve them on your own. For problems requiring critical thinking, we provide an approach before the solution, showing you how to interpret and solve the problem.”
