Chapter 1597

Several people heard the speech and immediately agreed.

These days, Zhang Feng didn't know what he was doing. He was busy. Zhang Feng had talked about these things before, but they gave them back to Zhang Feng in their fucking dream.

At this time, Zhang Feng said and stopped.

This made several people extremely painful. I went to find Ma Zhou. Feng Zi's Huoji gave me a password. Who dares to speak and beat who? It's hard.

These days, the waterwheel has been built.

But I don't know what went wrong with that thing. There's always no problem here, just where there's a problem, which makes several people anxious and can't stop.

What's more hateful is that Fengzi doesn't even say death.

But their father and people from the Ministry of work came to ask several times.

Seeing that the time for delivery to the phosphate fertilizer farm is coming soon, if you can't get it out at that time, don't say anything that can make thousands of people admire, let's get 50 boards first

At this time, you don't have to think about this classroom. It's a special place for teaching physics. At this time, Zhang Feng can actually come. It must be in the presence of so many people. Even if he doesn't want to talk anymore, he can't put his face down?

hey!

Several people smiled knowingly.

At this time, I'm shameless, and it's better than not being able to hand in things at that time. Go back and be beaten by my father and the emperor, isn't it?

"Get out of the way 1"

"Get the fuck out of my way!"

Chumo's loud voice and rough and crazy voice burst in an instant, which made the students a little scared and instinctively gave way.

But they dare not delay or offend these goods.

Zhang Feng in the classroom also heard the sound outside the door.

Although he knows that his arrival will attract many students, after all, this is his first time to teach seriously in the classroom, and students will naturally flock.

But he didn't expect so many people.

And these goods can't hold back at last.

Thinking of this, Zhang Feng also suspended the idea of preparing for the lecture, waved his hand and asked the students to open the front and rear doors and windows.

In an instant, the students outside the door, excited, quickly rushed into the classroom. Originally, the classroom was designed according to the classroom of later generations. A classroom can accommodate 60 people without being crowded.

instant.

The students in the whole classroom couldn't sit. A litter of people crowded in, even the old scholar and Hao Chujun, were forced to the podium. Some looked at the classroom, Ma Zhou, Cheng Chumo and others who were still crowded in.

Sons of men, Chumo and Chang sun Chong, Wei Shuyu and Wei Chi Baolin, finally burst into the classroom, but the wooden door

It's long gone.

Zhang Feng couldn't bear to look straight at several people and sighed: "all right, don't come in. If you squeeze down again, the house will burst!"

When they heard the speech, there was no crowding.

Seeing this, Zhang Feng picked up the chalk and wrote two words on the blackboard.

Geometry!

moment

Everyone looked at the two words and thought.

Zhang Feng said slowly, "do you know the meaning of these two words?"

The crowd was silent.

Zhang Feng was disappointed.

But at this time, Ma Zhou said cautiously, "mentor, this student seems to have seen it in the textbook before. It seems to be a kind of arithmetic?"

moment

Everyone suddenly.

Zhang Feng looked around and finally nodded with some satisfaction.

"Yes, it seems that you have done some work with these things."

These words were said by Du Gou and Chumo. The people who said them turned red and wanted to step back, but they couldn't step back.

Zhang Feng ignored several people.

After all, if you don't teach them a lesson, these goods will never remember the lesson.

At this time, Zhang Feng said slowly, "the so-called geometry is actually the accurate data to calculate the size of an object."

"The way we usually know to measure the data of an object is to use the measurement method and then give him a 50% discount. Although this is a method, sometimes it takes many times to calculate the accuracy of a thing in order to get the most accurate answer."

"For example, building bridges and houses are all places where these things are needed, and what I want to give you today is a more accurate calculation method for calculating any part of an object."

"At least, it can save time thirty times!"

"Hiss --!"

Everyone couldn't help taking a breath.

Arithmetic.

This thing is originally wonderful. Since the advent of mathematics, the time for calculating objects has been greatly saved, and it is more convenient. The opportunity to measure land and the measurement methods used in almost all places is slowly popularized

In other words, the knowledge of arithmetic began to sprout in the Tang Dynasty.

More people deeply believe that only reading can make them change their identity and status and soar to the sky. Those things can be learned if they find a master and learn crafts for a few days?

And last year, the Imperial College withdrew from the subject of mathematics.

But

There were only two or three people who came to study, and these people were forcibly arranged by their families, that is, to walk around and hide their faces from the emperor.

Almost everyone knows about it.

At this time, seeing Zhang Feng say so solemnly, there is something more awesome than arithmetic.

How can this not frighten all the students.
