100-100 Math Descriptive Type is a textbook that presents a standard for learning descriptive math, which students always find difficult and teachers always find difficult to teach.

① We have made it possible to understand and frequently use concepts according to the textbook description method.
② Knowing which elements are evaluated as well as understanding the problem allows you to check and improve your weak points.
Especially for descriptive questions, it is important to understand the grading criteria that reflect the examiner's intention.
③ If you do not practice writing it yourself, you may end up writing something other than what you intended in real life, which can result in a loss of points.
To become confident in descriptive questions, you must consistently practice writing them yourself.


This textbook reflects the newly revised content and organizes the textbook's core concepts. It selects the 40 most frequently appearing descriptive types, and is structured so that students can practice writing their own descriptive answers by following model answers and using twin problems.
And in confident ending, we have covered various types of transformation based on this training so that you can deal with any problem that may arise.
