Textbooks that reflect the changing curriculum
- Students entering high school after 2025 will either learn unnecessary content (content to be deleted) due to deletions, moves, and additions in the new curriculum if they study with existing textbooks, or they will learn textbooks that lack content that needs to be learned (content to be added).
But the fountain of mathematics perfectly reflects the changing curriculum.

Textbooks optimized for academy lectures
- The book, "The Fountain of Mathematics," is a collection of the author's passion from 20 years of teaching experience and the know-how he gained from teaching at EBS for over 10 years. It reflects the opinions and know-how he heard from teachers in the academy field, and focuses on the flow and difficulty of the content so that teachers can teach comfortably.

A textbook that builds confidence in math
- It is designed to help you easily understand the principles of mathematics through detailed explanations of concepts, and to build confidence in mathematics by focusing on problems likely to appear on school exams.
