There are two important elements in learning mathematics: one is 'understanding concepts and principles' and the other is 'application of concepts and principles'.
If 『Easy Thinking Mathematics』 is a textbook that focuses on understanding concepts and principles, 『Easy Thinking Mathematics』 is a basic textbook on elementary school mathematics problem types that focuses on applying concepts and principles.

『Mathematics for Easy Thinking』provides step-by-step instructions in the order of concept organization → basic verification problems → basic type problems → skill type problems to improve the ability to apply mathematical concepts, principles, and laws. In addition, the Power Book contains problems that are concentrated on mathematical process elements that can develop mathematics teaching skills, which is the biggest feature of the new curriculum, and provides great help in improving mathematical thinking skills.
