Chapter 22 Mathematical problems in this era can no longer be so simple.

Smart people get it right.

After Yu Hua inspired his thinking by tutoring his studies alone, all of a sudden, the mud that had been blocked in his head for a long time seemed to be activated in an instant, and a series of inspirations emerged, thinking about the education and training industry, and preparing to create a version of Yu Hua in the Republic of China. Mistakes in math make money.

After seeing Tan Qing's lavish spending, Yu Hua dare not underestimate the market potential of the education and training industry in this era.

The education and training industry in later generations is extremely prosperous, with an annual output value of hundreds of billions. Although it was finally hit hard and became a sunset industry, it is undeniable that the mentality of parents hoping their children will become dragons has laid the foundation for the existence of this industry.

Demand determines service!
Then, what about the education and training industry during the Republic of China?
The situation is unknown.

However, it is no problem to make money by making a set of math wrong questions by yourself.

A simple calculation shows that there are six classes in the second class of science in the whole school of Beiping No. 120 Middle School, from the first year to the third year. The number of students is about 60, and the market potential is [-] yuan.

But don't forget, this is just a school.

As long as the students of Peiping No. [-] Middle School buy a set of incorrect math problems, and take advantage of the reputation of the students of Peking No. [-] Middle School, they will expand the publicity to the entire Peiping area. At that time, the surrounding National Peiping No. [-] Middle School, the National High School Affiliated to Beijing Normal University, and the private Kongde Middle School will be available. , even as far away as the private Nankai Middle School in Tianjin, these are potential markets.

Besides, as a profiteer, ah, as an advanced young man who is good at helping his classmates to improve and improve their grades, in addition to making mistakes in mathematics, he can also make a collection of basic mathematics simulation problems, a collection of difficult key problems in mathematics, and various versions and types. not too much.

Finally, it's worth noting, is math enough?
The layout is small.

Physics, chemistry, biology and various science subjects can make mistakes in the problem sets, do basic simulation problems, and analyze difficult key questions, ensuring quality and quantity. , and understandable, and finally gave birth to the meaning of admiration, it is difficult to make money.

The pattern can't be small!

Decided to make money by doing wrong math questions first.

"In the early stage, I first sorted out the draft paper during this period, extracted the more difficult question types, deeply analyzed the question type structure, annotated the core problem-solving ideas, and compiled them into a book. As long as I take the math test for the first time this semester If you can score more than 90 points in the test, this set of math wrong questions will not worry about selling." After making a decision, Yu Hua thought in his heart and began to build a future framework.

During this period of time, the scratch paper used for writing questions is the foundation of a ready-made set of wrong questions. Fortunately, I didn't lose one, which can save a lot of time.

In the early stage, the set of wrong questions is obtained, and when the mathematics test score is above 90, there will be an example and basis for external promotion.

What is the concept of 90 points?
In this era of the 90% system, let alone 80 points, even if you can get [-] points in the test, you can be regarded as a ceiling-level existence.

As one of the top middle schools in the country, the No. 1 final math score of No. 85 class of science in Beiping No. [-] Middle School is only [-] points.

If he can score 90 points in mathematics in the first quiz this semester, Yu Hua can instantly jump to the first place in mathematics in the whole class, transforming himself into a student in the eyes of his classmates, and a child from other families in the eyes of countless parents.

In a sense, Peking No. [-] Middle School is the first in mathematics, which is equivalent to the first in mathematics among middle school students in the country.

With this foundation, it is feasible to promote the set of wrong math problems, and it is also feasible to sell the wrong set of math problems.

And with the big sale of math wrong question sets, the three wrong question sets about mid-term out-of-school promotion and physics, chemistry and biology can improve the schedule, and provide funds and fame for compiling a higher-level Yu Hua version of the five-year college entrance examination three-year simulation in the later stage.

A set of wrong questions in the early stage, a set of wrong questions for multiple subjects in the mid-term, and professional tutoring materials in the later stage. This is the future framework conceived by Yu Hua.

With knowledge to make money, no one has anything to say.

Soon, Yu Hua, who had completed the core main structure and future planning, already had a picture in his mind of the students of the Fourth Middle School and the surrounding schools racking their brains with their own set of wrong math problems. Thinking of this, a radian appeared on the corner of his mouth, and he couldn't help laughing.

In the later generations, the gangster Ge Jun killed millions of high school students across the country. Now Yu Hua has a small dream, which has become a nightmare in the hearts of No. [-] middle school students and students in surrounding schools.

Set up the entire money-making plan and framework, and do what he says, and Yu Hua immediately gets busy.

Time is life and time is money.

"This finale problem of solving inequalities with trigonometric function lines must be included, as well as this analytic geometry problem, um, yes, and the finale problem of solid geometry, the distribution of the roots of the quadratic equation in the function chapter can also be Add it..." After sorting out the drafts, with his excellent memory, Yu Hua quickly found a dozen math problems that he considered to be difficult and valuable from a pile of draft papers, and also selected from his own memory. Lots of good questions.

As for the scratch paper, I selected the trigonometric function line solution inequality finale, as well as analytic geometry and solid geometry, as well as a lot of functions.

As for the collection, one is not added.

In terms of own memory, select the penultimate number sequence + inequality question that I did on the National College Entrance Examination in my previous life. This thing was put up after the Olympiad changed it, and the perverted finale question that involves seeking the limit, all of which are all in the brain. go in.

Yu Hua can basically do the questions on the scratch paper. The math questions on the college entrance examination in his previous life are quite difficult, and he will not be able to do them for the time being. However, it is still too early. Headache topic.

In order to ensure the quality and quantity of Yu Hua's version of the mathematical wrong problem set, Yu Hua is carefully selected and strictly reviewed, and will never put any simple problems in it.

What is quality and quantity?

Quality is high-quality math problems, involving basic and introductory math problems, can it be called high-quality?

The quantity is enough to manage enough. Since you prepare a collection of wrong questions and sell it for fifty cents, you have to have a large quantity to manage your fill. If there are only a few questions, who would be willing to pay for it?
Yu Hua believes that he is a sincere person, not a profiteer. In order to help students improve their mathematics level, he resolutely eliminates topics such as the basic definitions of sets and functions.

Mathematical problems in this era can no longer be so simple.

Sitting at the table, Yu Hua carefully selected the topics of the wrong math problem set. After a while, there were footsteps in the corridor outside the classroom.

"Dong dong!"

A young girl wearing a women's coat stood at the door of the classroom, looked around, saw two male classmates in the classroom, stopped and reached out and knocked on the door lightly.

Hearing the knock on the door, Yu Hua put down the scratch paper, raised his head, and turned his eyes to the front door of the classroom. When he saw the girl wearing a women's coat, he asked aloud, "Come in, classmate, what's the matter with you?"

"Hello, classmate, my name is Lin Wan. Please come to the school hall at ten o'clock in the morning to attend the opening ceremony. Please inform the other students in the first class of science later." Lin Wan nodded and entered the classroom, came to Yu Hua, smiled, and said herself. After an introduction, he said.
