1.
This is a book that all students can read.

From students who are just beginning to those who are already good at math, everyone can build a solid foundation through this book.
Very easy concept explanations allow for quick acquisition of mathematical theories.

2.
We have broken away from the structure of standardized textbooks on the market that are repetitive in the form of “theory - proof.”

The structure of the textbook, which repeats the “Theory - Proof” section, is very difficult for those who are not familiar with mathematical language.
Hansisu offers a shortcut to break free from this structure and immediately improve your problem-solving skills.

3.
You can prepare for both school grades and the college entrance exam.

We have arranged the concepts and problems so that you can develop the ability to solve math problems for school grades and even the college entrance exam, starting from basic concepts.
In other words, if you study for the Hansi exam, you can naturally prepare for both your school grades and the CSAT.
