Features of this book
Complete computational learning in one semester, completed in one volume
Providing a learning diagnostic table for efficient computational learning management
Image association learning that makes computational principles easy and long-lasting to remember
One-page per day composition that never gets pushed back

1.
Master the principles of operation
The principles of calculation are explained in detail and organized using image association methods, so you can learn calculation methods easily and enjoyably on your own.

2.
A comprehensive guide to elementary arithmetic problems
This book covers all the operations required in the areas of geometry, measurement, regularity, and data, as well as the operation area, so that you can completely complete the operation study for the semester in one book.

3.
Strengthening problem-solving skills through textbook-linked learning
We have made learning easier by specifying the unit name of the operation being studied, and have provided word problems at the level of a textbook in the 'Strong Operations in Textbooks' corner to help students develop problem-solving skills.
