Chapter 21 Mathematics problems in this era can no longer be so simple.
A smart person can figure it out with just a few clicks.
As Yu Hua inspired his thinking through independent tutoring, all of a sudden, the mud that had been clogged in his head seemed to burst open instantly, and a series of inspirations emerged, thinking about the education and training industry, and preparing to create a Republic of China version of Yu Hua
Collection of wrong math questions to make money.
After seeing Tan Qing's generous spending, Yu Hua did not dare to underestimate the market potential of the education and training industry in this era.
The education and training industry in later generations was extremely prosperous, with an annual output value of hundreds of billions. Although it was eventually severely hit and became a sunset industry, it is undeniable that the mentality of parents who hope that their children will succeed laid the foundation for the existence of this industry.
Demand determines service!
So, what about the education and training industry during the Republic of China?
The situation is unknown.
However, if you think about it, it’s okay to make a collection of math mistakes and make money.
A simple calculation shows that there are a total of six classes in the second category of science classes in Peking No. 4 Middle School from the first to the third year, with a population of about 120 people. Each book costs 50 cents, and the market potential is 60 yuan.
But don't forget, this is just a school.
As long as the students of Peiping No. 4 Middle School buy the wrong math problem set, and use the reputation of the students of Peiping No. 4 Middle School to spread the publicity throughout Peiping, then the surrounding National Peking No. 2 Middle School, the National High School Affiliated to Beijing Normal University, and the private Kongde Middle School
, even the private Nankai Middle School as far away as Tianjin, these are potential markets.
Moreover, as a profiteer, ah, as an advanced young man who is good at helping his classmates improve and improve their grades, in addition to making math wrong problem sets, he can also make basic math simulation problem sets, math difficult key problem sets, various versions and types.
Not too much.
Finally, there is another point worth noting. Is mathematics alone enough?
The layout is smaller.
In various science subjects such as physics, chemistry, and biology, you can get wrong question sets, do basic simulation questions, and analyze difficult and key question types, while maintaining quality and quantity, which makes the students who are buyers feel their scalp numb when they look at it, that is, they feel that it is profound.
, and I can understand it. In the end, I have admiration, and it is difficult not to make money.
The layout cannot be small!
I decided to start making money by making a collection of math wrong questions.
"In the early stage, I first sorted out the draft papers during this period, extracted the more difficult question types, deeply analyzed the structure of the question types, annotated the core problem-solving ideas, and compiled them into a book. As long as I took the first mathematics test this semester
If you can get a score of 90 or above, this collection of wrong math questions will be a big seller." After making the decision, Yu Hua thought about it and began to build a framework for the future.
The scratch paper I used to write questions during this period was the basis of a ready-made set of wrong questions. Fortunately, I didn't lose any of them, which saved a lot of time.
In the early stage, we will find out the wrong question sets, and when we get a score of 90 or above in the mathematics test, we will have examples and foundations for external promotion.
What is the concept of 90 points?
In this era of the 100-point system, even if you can score 80 points, let alone 90 points, you can be considered to be at the ceiling level.
As one of the top middle schools in the country, the first place in the science class of Peking No. 4 Middle School only had a final math score of 85 points.
If he can score 90 points in the first math test this semester, Yu Hua will instantly jump to the top of the class in math, transforming into a top student in the eyes of his classmates and a child of other families in the eyes of countless parents.
In a sense, being No. 1 in Mathematics in Peking No. 4 Middle School is equivalent to being No. 1 in Mathematics among middle school students in the country.
With this foundation, it is feasible to promote the collection of mathematical incorrect questions, and it is also feasible for the collection of mathematical incorrect questions to sell well.
With the sales of the collection of wrong questions in mathematics, the schedule for mid-term out-of-school promotion and the collection of wrong questions for the three subjects of physics and chemistry can be upgraded to provide funds and reputation foundation for the compilation of a higher-level Yu Hua version of the five-year college entrance examination and three-year simulation in the later stage.
A collection of incorrect questions in the early stage, a collection of incorrect questions in multiple subjects in the mid-term, and professional tutoring materials in the later stage. This is the future framework conceived by Yu Hua.
No one can say anything about making money based on knowledge.
Soon, after Yu Hua completed the core main structure and future planning, the image of No. 4 middle school students and students from surrounding schools racking their brains with their own collection of wrong math problems appeared in his mind. Thinking of this, a curve appeared in the corner of his mouth, and he couldn't help laughing.
Later, the big brother 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 the students of No. 4 Middle School and the students of surrounding schools.
After establishing the entire money-making plan and framework, Yu Hua immediately got busy.
Time is life, time is money.
"This final question about the solution of inequalities on a trigonometric function line must be included, as well as this analytical geometry question. Well, by the way, there is also the final question about solid geometry. The distribution of roots of quadratic equations in the function chapter can also be included.
Add more..." After sorting out the drafts, Yu Hua quickly found out from a pile of draft papers a dozen mathematical questions that he considered to be difficult and high-value, and also selected some from his own memory.
Many good questions.
In terms of scratch paper, I selected the final problem of solving inequalities with lines of trigonometric functions that I just explained, as well as analytic geometry and solid geometry, plus a lot of functions.
As for the collection, I didn’t add one.
In terms of personal memory, I chose, for example, the penultimate question on sequence + inequalities that I had done in the national college entrance examination in my previous life. This thing was modified and put in the Olympiad, as well as the perverted finale question involving finding the limit, all of which were packed in my head.
Go in.
Yu Hua can basically do the questions on scratch paper. The math questions in the college entrance examination in his previous life were quite difficult and he won't do it yet. However, it is still early and there is still one month left before the first quiz. Yu Hua believes that he should be able to solve these confusing questions by then.
Headache problem.
In order to ensure the quality and quantity of Yu Hua's version of the collection of wrong math questions, Yu Hua carefully selected and reviewed them carefully and never included any simple questions.
What is quality and quantity assurance?
Quality refers to high-quality mathematics questions. Can mathematics questions involving basic and introductory mathematics be called high quality?
If you are planning to sell a collection of wrong questions for 50 cents, you have to be generous and manage enough. If there are just a few questions, who will be willing to pay?
Yu Hua considers himself a sincere person and not a profiteer. In order to help students improve their mathematics level, he resolutely eliminates questions such as basic definitions of sets and functions.
Mathematics problems in this era can no longer be so simple.
Sitting at the table, Yu Hua carefully selected the questions from the wrong math problem set. After a while, footsteps came from the corridor outside the classroom.
"Boom!"
A young girl wearing a women's coat stood at the door of the classroom. She looked around and saw two male classmates in the classroom. She stopped and reached out to knock on the door gently.
Hearing the knock on the door, Yu Hua put down the scrap paper, raised his head, and looked at the front door of the classroom. When he saw the girl wearing a women's coat, he asked loudly: "Please come in, classmate, what can I do for you?"
"Hello, classmate, my name is Lin Wan. Please come to the school auditorium at ten o'clock in the morning to attend the opening ceremony. Please inform the other students in Science Class 1 later." Lin Wan nodded and entered the classroom, came to Yu Hua, smiled and said to herself
