Answer and explanation

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!

1.
An explanation method that approaches familiar everyday language and explains it again using 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 a step further and naturally understand its nature.
This book presents concepts using everyday language familiar to children, with illustrations to aid understanding.
After that, we will explain the concept again using strict mathematical terms.
This way of organizing the explanation will have the effect of first seeing the forest of mathematics and then immediately following that, seeing 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 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.
