Stop using problem solving as a substitute for learning concepts!
First of all, make sure you understand the concept!
Math that embodies concepts through problems!
The most important concepts in math explained in an easy-to-understand way!

1.
An explanation method that approaches familiar everyday language and explains mathematical terms again.
Mathematics was created naturally to solve problems in everyday life.
Therefore, the terms used in mathematics are words that naturally emerged to explain something.
It may seem difficult and complicated, but if you know the exact meaning of the word, you can understand what it is, and even go one step further and naturally understand its characteristics.
This book presents mathematical concepts using everyday language familiar to children, with illustrations to aid understanding.
After that, we will explain the content in more detail using mathematical terms.
This structured explanation helps with overall understanding by first looking at the forest of mathematics and then looking at the trees of mathematics one by one.

2.
Problems that make the concept completely mine!
Are you memorizing "problem-solving methods" by repeatedly solving problems without reading the explanations? This book organizes the problems into steps so you can practice the concepts step by step.
Solving any problem requires going through several stages of thinking.
The problems are arranged step by step, from simple to difficult to solve, so that you can gradually digest the concepts you have learned and solve the problems.
