Chapter 45 Mathematics
With the computing power that Han Yang currently has, excluding all consumption, he can probably listen to 24 teachers at the same time 10 hours a day.

Based on a one-hour class, Zhixue.com would need 240 teachers to meet Han Yang’s needs.

Based on the purchase price of a class of 400 yuan, this would cost 9.6 yuan per day.

"No, no, it's too expensive. I can't afford it at this stage."

Playing power leveling on 99 computers, the money is all earned through hard work. Even if I play all the games in a day, I only earn more than 7 yuan, but I can't afford to spend it like this.

"Also, when the equipment from Mr. Lu is delivered, I will allocate computing power to make materials myself. Besides, the use of computing power cannot always be maintained at a high level. If you calculate it this way... let's find 20 teachers in the early stage. 20 classes a day, 8000 yuan. When my computing power improves and I earn more money, I can expand the scale."

If you can only take 20 courses at the same time, it will be more particular about which courses you should take.

Although Han Yang has to learn the entire knowledge system, there is always a priority.Study the most important subjects first.

After thinking about it, Han Yang finally made a decision.

At this stage, apart from computer knowledge, the most important thing for me is mathematics.

Mathematics is the foundation of all natural sciences and has an unparalleled importance.

There are many categories of mathematics. At this stage, Han Yang can only choose a few mathematics branch courses that are highly related to computer science to study.

After thinking about it, Han Yang decided on 10 courses including vector algebra, analytic geometry, series theory, ordinary differential equations, mathematical statistics, and stochastic processes.

According to normal university teaching arrangements, these subjects require at least a whole semester, that is, half a year to complete.Most even take four semesters.

Even if you finish studying, you have only learned some preliminary things.If you want to study further in the future, there will be some torturous things.

But Han Yang was certainly not afraid.

After initially deciding on 10 mathematics courses and 10 computer courses, Han Yang immediately contacted Zhang Dong and asked him to help him invite teachers from Yunshan University who could carry out corresponding courses to the website.But I made a call but didn't get through, so I had to contact him later.

At this moment, Zhang Dong's family was in a gloomy mood.

Zhang Dong and his wife were sitting on the sofa, and opposite them sat a woman with gray hair and a haggard face.

This woman looks to be in her 50s.But Zhang Dong knew that she was only 45 years old, the same age as him.

"Xiaojuan, don't be too sad."

Zhang Dong's wife persuaded him softly: "Old Li can't bear the blow for a while. Let Zhang Dong try to persuade him after a while, and he can always cheer up."

Xiaojuan cried and said: "I work hard to make money every day to support this family, but where is Lao Li? He is drunk all day long. After drinking too much, he curses the world and the school leaders. It is impossible to live this life."

Brother Zhang, you and Lao Li were good friends when you were in college. After graduation, you went to Yunshan University to work as teachers together. You two have the best relationship. You should go and persuade him to stop drinking. He will lose his job as a university professor. Even if he is lost, I don’t despise him. As long as he can cheer up, find a job, and live a good life, our family will still be a family.

If he keeps doing this, I really can't stand it anymore, and I will divorce him with my children! "

Zhang Dong sighed deeply.

Lao Li's name is Li Hui, and he and I have always been close friends.But I am from the computer department, and he is from the mathematics department.

Both of them taught at Yunshan University, but Li Hui was unlucky.Once I met a male student bullying a female student by chance, so I stood up to stop him. It turned out that the male student had a background, and his family connections were so close that he could vaguely connect with the Eta people. After slandering him, he turned out to be... Li Hui is bullying female students.

It's great now. I lost my job and became a molester.

Li Hui couldn't bear the blow, and he was banned from entering the education field, so he couldn't recover.Zhang Dong wanted to help him, but was unable to do anything.

"Hey. It's a pity that Manager Han only has lecturers from the computer department, not the mathematics department..."

With a sigh in his heart, Zhang Dong comforted him: "Okay, Xiaojuan, I'll go and persuade him."

After finalizing the matter, Zhang Dong was able to take out his phone.At this moment, he immediately saw two missed calls from Han Yang.

"I'll make a call."

He walked to the study and dialed back.

Han Yang's voice came out immediately: "Professor Zhang, this is it. Do you know the teachers in the mathematics department of your school? Our website wants to purchase ten mathematics-related courses and needs ten mathematics teachers..."

Zhang Dong was stunned there, feeling his heart beating wildly and uncontrollably.

He is already over 40 years old, how can he still not understand that simple comfort and advice have no effect?
Li Hui's heart knot can be opened with a few words of comfort and advice?
impossible!
There is only one way to open his heart, and that is to give him a new job that gives him a sense of self-realization and value.

Originally this was an unsolvable problem.Because I am just an ordinary person.But now, the opportunity to revive his best friend of many years appeared before him without any warning.

Zhang Dong organized his words carefully and said a little humblely: "Manager Han, I happen to know a mathematics professor who is absolutely excellent in professional knowledge. You can rest assured. It's just...

He was expelled from school.But he was slandered!We’ve known each other for decades, I can vouch for that! "

Zhang Dong told Li Hui's story.

Han Yang immediately agreed: "Okay, no problem, let him make the first lesson as soon as possible, and we will evaluate it as soon as possible!"

After hanging up the phone, Zhang Dong clenched his fists with excitement.

After walking out of the room, Zhang Dong immediately rushed to Li Hui's house without saying a word.

In broad daylight, Li Hui smelled of alcohol and was sitting on the balcony in a daze.There were bottles of wine everywhere in the house and garbage on the floor.

"Li Hui! Do you still want to be a teacher? Do you want to teach mathematics?"

Li Hui raised his head, looked at Zhang Dong blankly, and smiled somewhat self-deprecatingly.

"If you still want to teach math, cheer me up immediately. Now, take a bath, get a haircut, and shave! Get him a set of clean clothes to change into, and prepare lessons for me immediately!"

It was already night when Li Hui stood in front of the mobile phone camera.Now, his hair has been cut short, no longer unkempt, and all his beard has been shaved off.

He was wearing casual clothes, holding chalk in his hand, and a blackboard behind him, just like an ordinary teacher.

Outside the camera, Xiaojuan, Zhang Dong, and Zhang Dong's wife looked at him eagerly.That blazing gaze gave Li Hui a very strange, yet somewhat familiar feeling.

Facing the camera, he was slightly nervous.

"The so-called random process is a branch of probability theory..."

After clearing his throat, he began his first lecture after being away from the podium for several years.
