Let's wake up our sleeping math brain, starting with high school math!

Mathematics is already closely related to our lives, including artificial intelligence, data analysis, economics, and games.
Math is now becoming a required subject rather than an optional one, so I feel the need to acquire a certain level of knowledge, but it is true that looking through old workbooks or theory books can be scary or burdensome.
This book contains only the essential concepts to help you efficiently review the math knowledge you've forgotten since high school.
Rather than simply memorizing formulas and solving problems, we focus on understanding the meaning of equations by showing in detail how the formulas are developed and what results are produced.
If you want to build a solid foundation in math, start with this book.
