Answer and explanation

1.
Unfamiliar concepts are first presented in pictures and everyday language.
In textbooks, a function is defined as 'a relationship in which, for two variables x and y, the value of y is also determined to be one as the value of x is determined to be one.'
Even though it is clearly written in Korean, it is difficult to understand at first glance.
So, in “Linear Function Concept Comes First 1,” we first explain functions by presenting examples that are easy to understand through pictures.
This book presents the concepts first with intuitive illustrations before providing rigorous mathematical definitions, and then explains the concepts again in mathematical terms.
If you find functions difficult, try studying with the "Concepts Come First" series, which will help you understand the concepts. You will be able to study functions easily and enjoyably.

2.
Present the basis of logic!
Because mathematics is structured logically, if there is a hole at any stage, it is difficult to build new knowledge thereafter.
However, learners often neglect to study the parts that do not appear on the test.
It may be okay now, but over time, this will create gaps in your logical thinking, which will hinder your ability to learn math properly.
In order to fill in such gaps, 〈Linear Function Concepts Come First 1〉 has structured the content tightly, presenting sound logical grounds even for the smallest details.

3.
The important thing is big! In image!
You might think a book that explains abstract mathematical concepts mathematically would be difficult, right? Not at all!
This book explains abstract concepts in a way that is easy for learners to remember.
The content is developed with interesting materials and pictures, and the intensity of the content is effectively expressed so that important information can be seen at a glance.
Discover "Linear Function Concepts Come First 1," an intuitive design that lets you grasp concepts at a glance, with rich explanations and helpful problems.

Very, very friendly answer sheet!
Even though we know how to solve a problem, there are more cases than you might think where we make mistakes in calculations.
And sometimes, when you're so absorbed in calculating something, you forget what you were calculating.
Here's a special answer sheet to help you answer all the questions you know.
The entire calculation process is detailed, as if the teacher had solved it by hand, and various clues hidden in the problem are highlighted with colors and arrows, so that you can intuitively know how to use them at which stage.
Let's upgrade our friends' calculation skills to the next level with the special answer sheet for "Linear Function Concepts Come First 1."
