Stop learning math concepts by solving problems!
First of all, make sure you understand the concept!
Math that embodies the concepts you understand while having fun solving problems!
Throw away problems for the sake of problems!
Only the problems necessary to solidify the concept have been carefully selected!
The most important concepts in math explained in an easy-to-understand way!

A two-step explanation method that approaches familiar everyday language and then revisits mathematical terms.

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 nature.
This book presents concepts using everyday language familiar to children, with illustrations to aid understanding.
And on the next page, we'll break down the concepts again using rigorous mathematical terminology.
This two-step explanation method will allow you to first see the forest of mathematics, and then immediately move on to see the trees of mathematics one by one.

Problems that make the concept completely mine!

Are you memorizing "problem-solving methods" by repeatedly solving problems without properly reading the explanations? This book presents problem-solving methods that will help you truly internalize the concepts.
Rather than simply arranging the problems from easy to difficult, the problems are arranged in stages so that you can practice the concepts step by step.
Solving any math problem requires going through several stages of thinking.
It arranges problems step by step, from simple ones to ones that require thought to solve at the final stage, allowing you to fully digest and absorb the concepts you understand.
