The Plus Basic Book for Systematic Concept Learning, The Concept Black Label

1.
Expanded concepts from basic to integrated and advanced

It includes the basic concepts presented in the curriculum as well as extended concepts that will help you solve real-world problems.
We have provided examples, proofs, explanations, references, and cautions for the concepts to help you understand them clearly.

2.
Systematic learning possible with two-step type corner

After learning the concepts, we have structured the questions so that students can choose and study problems that are appropriate for their level, from the 'basic types' covered in the textbook to the 'essential types' that they will frequently encounter in actual exams.
In particular, for the 'essential types' that can be perceived as relatively difficult, we provide solution steps so that students can learn on their own.

3.
Insert the latest past exam questions

We've included essential questions, questions reflecting the latest trends in past exam questions, and developmental questions that will expand your thinking skills, helping you improve your skills.
Additionally, we have marked frequently appearing descriptive questions, newly introduced questions, and difficult questions for each unit to help you practice.

4.
Detailed explanation provided

We have provided detailed explanations of the solution process so that you can immediately understand the solution just by looking at the solution.
In addition to the basic solution, we provide other solutions that are easier and faster to solve, allowing you to think in a variety of ways.
Additionally, supplementary explanations are provided to help solve problems by explaining principles and extended concepts, adding corrections to solutions, and avoiding incorrect answers.
