Answer and explanation

1.
Contains the principles of equations!

As with everything else, getting the first button right is more important than anything else in the equation.
It is important to clearly recognize that an equation is not just a simple expression, but an equation. This is because when solving a problem, you can look at the problem from the perspective of an equation, find the points where you can create an equation, and create an equation.
An equation is a formula that uses = to indicate that the values ​​on both sides are equal.
Although things that are the same can be expressed as equations without difficulty, there are times when, in order to solve a problem, we need to transform the expressions into equations so that things that are not the same become the same.
So, how do we make things different equal? ​​Check out "The Concept of Linear Equations Come First 1"! "The Concept of Linear Equations Come First 1" isn't just a book about how to solve equations; it also truly covers the principles of equations and equality.
That's why, with "Linear Equation Concepts Come First 1," you'll be able to build a foundation in mathematics that will allow you to solve new types of problems!

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 『The Concept of Linear Equations Comes First 1』, we have carefully structured the content to fill in such gaps, 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 Equations: Concepts Come First 1," an intuitive design that lets you grasp concepts at a glance, with rich explanations and comprehensive 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 take our friends' calculation skills to the next level with the special answer sheet for "Linear Equation Concepts Come First 1."
