Everyone was surprised.

It would be smoky.

Shouldn't Yan Fei be at home now?

How did you come to Heyu Teahouse?

They found out through Fan Erye yesterday that Yan Fei will not be lecturing for the past two days, and will only teach after the ceremony of inviting immortals.

They also felt that Yan Fei just had a good rest.

As a result, I didn't expect that Yan Fei actually came tonight.

And it was a little early.

Many people's eyes became excited. Could it be that Miss Yan Fei is going to explain the law class again?

That would be awesome.

They originally liked listening to music and books, but after listening to Yan Fei's law class, they liked listening to lectures again.

Some people even felt that if they didn't listen to Yan Fei's law class for a day, it would make their whole body uncomfortable.

"Smoke Fei."

Looking at Yan Fei who walked in, he was stunned by Fan Er Ye of Yu Teahouse, why did Yan Fei come.

Last night, I told him that I would not teach law lessons for the past two days, and I would talk about it after the ceremony of inviting immortals was over.

Today, I came here with a book in my arms. Are you trying to teach a law class?

He also saw that Yan Fei didn't teach law lessons, and he and Yu Teahouse lost a lot of popularity.

In the past, when Yan Fei was giving lectures every day, his He Yu Teahouse was full, and everyone around him crowded the corridor, just to listen to Yan Fei's law class.

Then without Yan Fei teaching the law, he and Yu Teahouse were already full of people.

But he doesn't care about these popularity.

After all, I opened this and Yu Teahouse myself to listen to these people's discussions.

He is old and likes to be more lively. He sees that his teahouse is full of people. Even if he does not drink tea, he is happy.

Seeing Yan Fei come in with the book in her arms, Erye Fan said with a smile, "Is there something wrong with Yan Fei coming tonight?"

In Fan Erye's opinion, Yan Fei should have come to talk about the time for the law class after the ceremony of inviting immortals.

"I'm here to teach."

Hearing Fan Erye's words, Yan Fei smiled and said, "But it's not a law class, but a math class."

"lecture?"

Hearing Yan Fei's words, Fan Erye was surprised that he was actually giving a lecture.

But in the next second, I heard Yan Fei's math class, and I was stunned.

What is a math class, can it be counted?

Or an algorithm class?

He has lived most of his life and has never heard of a math class in.

Chapter 464: An Attractive Math Class

However, the word mathematics is still very easy to understand.

It should be about arithmetic.

But even so, he didn't understand, Yan Fei was so good at doing arithmetic.

Yan Fei is a lawyer, so if she is lecturing, she should give another law class.

"Yes."

Yan Fei smiled and said, "Anyway, I'll talk about it in a while, and everyone knows it."

"Row."

Hearing Yan Fei's words, Fan Erye nodded: "Then you can go and talk, there are some people there, old man, I will also listen to your math class."

"Ah."

Yan Fei nodded and walked to the middle of Heyu Teahouse.

At the present time, Liu Su, the storyteller of Heyu Teahouse, was not there either. He was resting and went to eat.

So when Yan Fei came up, it came directly.

"Miss Yan Fei really gave a lecture!"

Seeing Yan Fei on the lectern and the people sitting in Heyu Teahouse, his eyes suddenly lit up.

Miss Yan Fei is really teaching.

They just saw Miss Yan Fei coming in, and they thought that Miss Vision was talking to Fan Erye about something, so they didn't ask Yan Fei.

As a result, I can see now that Yan Fei went directly to the middle of the podium. Is this a lecture?

"Is Miss Yan Fei going to give a lecture?"

Someone couldn't wait to speak out: "Didn't you say yesterday that there will be no law class for these two days, and that the class will only be taught after the "May [*]" Liyue invitation ceremony?"

"Well, I want to teach a math class today, not a law class."

Yan Fei smiled and said, "I found a very interesting course that I can share with everyone. Compared with the law, I think mathematics is also very interesting."

Although the Heyu Teahouse was not full, Yan Fei still decided to continue talking.

Just to see how it reacts.

"math class?"

"It's not a law class. I thought it was a law class."

"What is a math class, is it more interesting than the law?"

"I believe Miss Yan Fei, Miss Yan Fei said it was interesting, it must be very interesting."

"Math class, could it be that arithmetic is not good? After all, it is mathematics."

.........

Hearing Yan Fei's words, the eyes of one person after another suddenly lit up.

Even if it wasn't a law class or a math class, they were willing to listen to it.

Miss Yan Fei is on fire. Math is more interesting than the law. They really want to listen to math class.

At this time, as Yan Fei came to Heyu Teahouse, some people around Heyu Teahouse also came over one by one.

When they heard what law class Yan Fei was going to teach, they were all very curious.

It was the first time they heard about math class,

Then they saw that Yan Fei had posted a large white paper.

Everyone didn't know why, but still watched curiously.

"Math is naturally related to numbers. The mathematics I want to teach starts with recognizing symbols. I won't talk about simple addition and subtraction. I will tell you a simple method."

At Heyu Teahouse, Yan Fei took a pen and wrote five symbols on white paper.

"This is the symbol representing the plus sign, followed by a minus sign, a multiplication sign, a division sign, and an equals sign. Let's first recognize these five numbers"

"The plus sign is very simple, that is, one hundred plus one hundred, then = two hundred, see this symbol clearly, this is the = sign."

"What is a multiplication sign, that is, multiplying numbers."

"Look at my two circles, which represent two chickens. I drew six circles, and every two circles are on a block, that is, it represents six chickens, and there are three twos added together, right?"

.........

In He Yu Teahouse, Yan Fei talked eloquently, from the most basic addition and subtraction to multiplication, and everyone who listened nodded.

They all know what Yan Fei said.

Until Yan Fei talked about the appearance of the multiplier, many of them's eyes became glowing.

In this way, it is really easy, there is such a symbol.

"Adding a few digits, the final number obtained is exactly the same as the so-called multiplication."

"I see. Is this a multiplication number? It's too convenient. Three times two is six, and it can also be read as two times three."

"My God, if I can count like this, I can become a teacher."

"I've never seen such a symbol, and the teacher has never taught it. I didn't expect Miss Yan Fei to understand it so well."

"Now that you've seen it, this symbol is really awesome and convenient."

...........

A group of people looked at Yan Fei, who was talking eloquently, and the words written by Yan Fei. All of them looked at them with glowing eyes, and their faces were excited and excited.

Especially some businessmen, who took a look by the way, did not expect that they would learn something very interesting, and immediately became addicted to it.

When Yan Fei was lecturing in Heyu Teahouse.

In the jar shop.

Hu Tao looked at Gui Si who came back, her beautiful eyelashes wrinkled: "Then why come back so late."

You know, Guisi should have come back with Fire Dinosaur, but Fire Dinosaur came back in the afternoon, but Guisi did not come back.

Although I don't worry about Guisi very much, Guisi is not good at keeping time.

"S."

Hearing his master's words, Gui Si hurriedly explained, and kept making noises, and Hu Tao was stunned for a moment.

She couldn't understand what Gui Si said at all.
