Math is a subject that requires memorization!

Teacher Hyunjeong Kim, who has been working as a math education expert for over 30 years, has put the core of studying math into one book.
Surprisingly, the secret is the conclusion that 'math is a subject of memorization.'
It is said that mathematics is a subject where 'understanding' is the most important, but in reality, mathematics is a subject that requires memorization of concepts and formulas to solve problems.
If we acknowledge that math is a subject that requires memorization, our approach to math, which used to be a headache just thinking about it, can become equal to that of other subjects.
It's not that you don't understand because you're stupid, but because you don't study consistently and diligently and just jump into problems without any tricks, so you can't solve math problems smoothly.


There are quite a few people who don't know how to study math.
Parents are well aware of their children's abilities, but they may not be able to realistically recognize them, and children always find boring and difficult math overwhelming.
However, there are students who started studying math during the summer break of their second year of high school based on the author's math study method and received a top grade on the college entrance exam, and there are also many students who did not study at all during middle school but studied hard during the winter break of their third year of middle school and were admitted to prestigious universities.
The author emphasizes that if you don't think it's too late and gradually learn and memorize the concepts, and then consistently solve problems, math will become familiar to you and you will be able to achieve the grades you want.
As a mathematics educator, I will teach you various and specific study methods that will help you make mathematics an easy subject that can be enjoyed by the many, not just the exceptional few, through principles and study methods that I have cultivated over many years of experience and practice. Above all, I will teach you various and specific study methods that will help you achieve high grades.


If you understand through memorization and develop problem-solving skills, your math grades will definitely improve!

The goal of studying math is to improve one's skills, and the ultimate goal is to enter college.
To achieve the goal of college entrance, test scores are the most important, and there are clear tips for maximizing your abilities on the test.
"Math is Memorization" is the "essentials of studying math" that introduces a math study method that will truly improve your skills and ensure higher grades.
So, what and how should we memorize to study math properly?
You must memorize the basic concepts of definitions, terms, formulas, and problem solving.
Definitions are the basis of all concepts and formulas in mathematics.
If the foundation is not solid, no matter how splendid the building is built on top, it will inevitably shake.
Additionally, if you do not understand and memorize the meaning of mathematical terms when solving problems, it will be difficult to properly approach the problem and you will not know how to solve it.
This is why reading comprehension is important in mathematics.
Formulas, which are also called the flower of mathematics, must not only be memorized, but also organized and proven in the corresponding unit.
If you can't prove the formula, you're more likely to make mistakes when calculating in actual problem solving, and the time it takes to solve the problem will increase.
The mother concept used in problem solving is the concept that can be used by looking at the answer sheet, and you only need to memorize one concept that is the simplest and clearest to calculate.

In addition, the author repeatedly emphasizes that memorizing definitions, properties, terms, and formulas for each unit is the royal road to studying mathematics.
Since mathematics is a subject of proof before it is a subject of problem solving, being able to prove and explain the formulas in the concept book is proof that you are studying mathematics properly.
The process of deriving the formula is somehow used in problem solving.
And then, by reviewing related concepts and deriving formulas, you will study and develop the ability to solve problems on your own.
Just like a Korean textbook, you should read every single chapter of your math textbook! Memorizing the table of contents for each math unit will help you grasp the content within that unit. Memorizing the table of contents, main text, and practice problems in the concept book will help you access them immediately when solving real-world problems.
In solving math problems, reducing the time required is so important that it can be a key factor in determining university rankings.


The bible for improving math scores, from basic concepts to solving killer problems and guaranteeing college admission!

"It's annoying, but do I really have to memorize formulas?" "I've already studied an entire concept book, should I buy a new one and study it again?" "Do I really need to make an error notebook?" "Math is Memorization" provides solutions, along with supporting evidence, to countless concerns we've encountered while studying math.
We present detailed, proven and effective study methods for math that are easy to overlook and can be used immediately on actual exams.
The 'skeleton learning method' developed by the author is a study method that allows for precise definitions, formulas, and concepts.
It is a method of accurately understanding the concept, proving the formula, and solving problems based on it. The framework means 'concept formula + related essential problems.'
Meanwhile, the 'basic rooting learning method' is a top-down study method.
This is a method of going down to the lower concepts of a certain concept, finding the root from which it originated, and then reorganizing the concept from that root.
When you are studying and the concepts are confusing and you desperately need the concepts of the process below, it is very effective.
Also, the best notebook for mistakes is a math book that you have studied consistently, a workbook that you have properly finished, test papers, and past exam questions.
The test papers you solve yourself are a great asset, and if you just get the wrong answers on the test paper right, your skills will improve significantly.
Creating a separate notebook of error answers is just a waste of time.
In addition, it includes specific, practical, and experiential learning methods, such as solving math problems on lined notebooks to systematically organize concepts and formulas, looking over a math concept book repeatedly, writing down concepts and formulas on the problem and solving it to solve it more accurately, and ‘blank test’ and ‘writing down the main concept and solving the problem’.


We also did not leave out solutions to the 'killer questions' on the college entrance exam, which is so important that it can affect college admission.
The score for the CSAT exam questions is 2, 3, and 4 points. 2 points goes to the easiest question that can be solved in 20-30 seconds, 3 points to the next most difficult question, and 4 points to the most difficult question.
It is better to leave aside the so-called most difficult killer problems, numbers 15, 22, and 30, and start with the problems with lower scores.
Among the three killer problems, number 15 is surprisingly easy to solve, so solve it first and then move on to numbers 22 and 30.
To get a high grade on the CSAT, you need to get at least two out of three killer questions correct, but if you're aiming for a grade 3 or 4, you can skip these killer questions.
If you are not confident about the killer problem, it is a good strategy to boldly give up and solve the remaining problems with certainty.
The conclusion is, 'Let's start with easy problems that we know and solve them thoroughly.'


If we break down our biases and find more effective methods, math can become a more fun subject than any other, and a subject where grades honestly improve in proportion to the effort put in.
The author hopes that no student will waste time and ultimately give up on math because they can't find the right method, and that "Mathematics is Memorization", which condenses 30 years of math teaching know-how, will become the new bible for studying math.
Let's start by 'reading' the math textbook right now!
