Jiang Qiye stood on the podium and began to fiddle with the multi-functional podium.

Several students sitting in the classroom turned their eyes to Jiangqiye in surprise.

"Student, there are classes here!"

A boy sitting in the front row with glasses whispered to Jiang Suye.

"I know! Didn't your teacher tell you?"

Jiang Qiye raised his head and asked curiously, and Li Ning would tell the school committee of their class that there was a teacher in the class.

"You are the substitute teacher?!"

The boy spoke in surprise. After all, Jiang Qiye looked too young, and he thought this was the senior.

As class time progresses, the entire classroom is filled with people one after another.

Just when class was about to begin, several teachers suddenly came in from the door. They first glanced at Jiang Qiye and walked straight to the last row of the classroom.

Then, Jiang Qiye looked at them and was stunned.

Is this here to listen to the class?

At this moment, the class bell rang.

Jiang Qiye came to his senses, said nothing, and coughed gently, "Okay, your teacher Li Ning is on a business trip, I'll help him with a class."

The implication is that you can leave the next few teachers who are listening to the class.

Seeing the teachers sitting behind him without any movement, they raised their heads and stared at him with interest.

When Jiang Qiye saw this situation, he was a little confused for a while. He couldn't be here to listen to his lectures, right?

Open PPT and turn to the first page.

"Do you know how probability theory developed?"

"Everyone knows that most of the modern Western scientists are nobles, so many people like gambling. In the early years, gambling was just a deduction plate or a magnitude, and all the probabilities seemed to be the same."

"But when you gamble, you find that you are always losing money. When they see, it won't work like this. Shouldn't it be a matter of waiting for probability? Why do you always lose? In order to win money, a large number of mathematicians began to study the probability problems behind gambling, and gradually discovered that there were many rules behind time that seemed to be waiting for probability, so they started to make money when they went to the casino."

"Later, the dealer found that this group of mathematicians had been winning money, so it would definitely not work if this continued. They also began to ask some mathematicians to help improve gambling equipment, so the subject of probability theory was developed in the confrontation between the two sides."

Jiang Qiye talked about the current discipline development from the history of the discipline, and then started writing on the blackboard with chalk.

Because the second chapter has just begun, the difficulty is not particularly high.

He was talking while writing on the blackboard. Jiang Qiye did not use Li Ning's PPT. If there was no teacher to listen to the class, he would directly plan to chant PPT and touch these two classes.

But looking at the teachers sitting behind the classroom listening carefully while taking notes, PPT was obviously inappropriate because PPT was Li Ning's own understanding.

Although I don’t know why these teachers came to listen to the class, Jiang Qiye still decided to take the class seriously according to his own understanding.

Jiang Qiye on the podium had already finished writing on the blackboard one by one, and stood on the blackboard to signal the students in the classroom to take notes.

Looking at most of the classrooms without movement, Jiang Qiye wiped the sweat from his forehead and said with a smile, "Although I didn't give you the final exam, I can be sure that the final exam will be taken!"

As soon as Jiang Qiye said this, the students who did not move in the classroom took out their phones and started taking pictures at the blackboard.

A professor sitting behind the classroom nodded when he heard Jiang Qiye's words, and silently marked the second chapter on his notebook.

Jiang Qiye almost racked his brains, trying hard to keep his lectures from being boring, and to expand the complex things to a simple and easy-to-understand field.

So almost all the students in this class listened with relish, and few of them were distracted and played with their mobile phones.

The university courses are advancing very quickly. When Li Ning asked him to substitute classes, he had no other requirements. Only here is a little bit of it, he made some small requests for Jiang Qiye.

Therefore, Jiang Qiye spoke very quickly.

After a class, the first two sections of the second chapter of the random variables and their distribution were completed like a rocket.

It is impossible to take notes in class. It is already very good to keep up with the teacher’s lectures in college. The students below kept taking photos with their mobile phones, which was very similar to the press conferences of some technology companies.

"Hey, can you understand what I'm talking about?"

During the break, after Jiang Qiye turned off the projector, he casually asked several classmates sitting in the front row.

"Uh, that's OK, you've made it very clear."

"Oh, that's good!"

Jiang Qiye was afraid that he would speak too badly and did not follow the PPT. If they didn't understand, they wouldn't even find a tool for self-study.

As for reading books?

Anyone who has been to college knows whether books are the same in college classes.

Soon, the bell rang for the second class.

Because of the feedback from classmates, Jiang Qiye started to explain with confidence.

After a while.

The students sitting in the classroom looked at the dense blackboard writings on the blackboard in a confused look, and turned into emotional photography tools.

No, I know the Fourier Transformation, but isn’t that something of a high-level mathematics? It seems that there is no such thing in this book?

Only a few people can barely understand what Jiang Qiye is talking about.

The boy sitting in the first row and having sex with Jiang Qiye before was staring straight, the pen in his hand stopped and complained in a low voice.

"Damn, what's the thing about this??"

The classmate sitting next to him looked at the blackboard and blinked.

He had already stopped getting up to it ten minutes ago. When he heard his roommate's complaints, he also responded in a low voice, "I seriously suspect that it was your words just now that caused this boss to misunderstand us."

Seeing that Jiang Qiye had already stood aside and gave up the blackboard, he quickly raised his phone and took a complete photo of the blackboard.

Looking at the blackboard that was almost full of writing and holding a cell phone to take pictures, my face was smiling, but my heart was desperate.

Instead, the teachers who had been sitting behind him became more energetic at this time and recorded Jiang Qiye’s lecture with a smile. They naturally could understand what Jiang Qiye was saying.

The moment when the bell rang for get out of class, a look of relief appeared on all the students' faces.
Chapter completed!
