Epilogue
What have you done to ensure proper math education for your children?

This book answers the question of what we, as adults in this country, should do for students who struggle with math no matter what we do.
Additionally, it will help adults who have suffered from feelings of inferiority due to their poor math skills in the past regain their self-esteem, even if it is late, by letting them know that it was not their fault.

If, over the past 70 years, mathematics educators have taught mathematics independently, gaining recognition for their expertise and authority, and as a result, 80% of the population has become mathematics dropouts, then it is time to acknowledge the failure of mathematics education and put aside their self-righteousness and stubbornness.
An expert is someone who has done something deeply and if he or she is good at solving problems, his or her authority should be recognized.
However, if not, you may end up falling into the trap of being an expert and may become an object of avoidance.


No one would rely solely on climatologists to solve the problem of global warming.
Scientists, businesspeople, and people around the world will feel the need to speak up and contribute to the cause in their respective fields.
We must abandon the idea that we can only rely on mathematics educators who have repeatedly failed, and recognize that the crisis in mathematics is a community problem.
The goals of mathematics education have been damaged by the flawed mathematics education that mathematics educators have created, preventing students from developing their abilities.
In the end, for 70 years, the subjects of mathematics education were subjected to incorrect logic and became entangled.
Due to the so-called misconceptions of teachers and experts, parents, and students, it has become a situation where it appears that people are studying mathematics, but they are not studying mathematics.

Identifying the problem is important for proper problem solving, but if there is no solution, it only adds to the burden.
This book addresses the misconceptions people make to avoid problems and suggests solutions.
You can expect the author's sharp problem awareness and excellent solutions.
