The beginning of a math quitter starts with fractions in the third grade of elementary school!
Math becomes difficult if you don't properly understand and move on from fractions.


1.
If you start from the meaning, math isn't difficult!
There are three types of fractions: proper fractions, improper fractions, and mixed fractions.
Are you finding this unfamiliar word difficult? Don't worry.
Once you know what each name means, you'll naturally understand why each fountain is shaped the way it is.
Rather than just memorizing fractions, we help you study math naturally by explaining their meaning.


2.
I visualized the basic formula!
When learning a concept, you approach it from the meaning of the term, but there are formulas that you definitely need to learn to use it to solve problems.
So, I visualized these formulas as simple geometric images so that they can be intuitively understood and remembered for a long time.
The reasons and mathematical proofs for why such formulas are valid are also kindly explained.

This is a math book with video lectures!
You can watch the orientation lecture by scanning the QR code on the book cover.
You can check what content is included in the book and how to study fractions effectively.
And you can study all concepts from the first to the last unit by watching video lectures.
You can watch the lecture immediately by scanning the QR code without separate registration.
Check out this delightful, refreshing, and invigorating lecture from a former EBS math teacher right now!

★★★ Great for students like this!
- Friends who are good at finding answers, but don't know the concept when asked about it
- Friends who sometimes get the same type of problem right and sometimes get it wrong

★★★ A math book worthy of the name!!
Mathematics is often said to be beautiful because it presents the necessary truths in a clean, uncluttered way.
We are solving the concept of fractions in the most mathematical way possible.

★★★ A book that proves that math books can be pretty too!!!
A math book with a pastel-toned layout that resembles a fairy tale has been published, unfolding mathematical concepts through illustrations.
Add fun to your studies with these pretty math books.
