Datang: I am so happy to marry a disfigured princess!

Chapter 175 You call this counting?

When Lin Heng said this, Li Lizhi was naturally unconvinced, because Lin Heng didn't play according to the routine at all, and even a person would be pissed half to death!

At this moment, Li Lizhi wanted to go up and kick Lin Heng to discourage him.

"You just like to make me angry, right?"

Lin Heng waved his hand: "If you insist on saying that, I can't help it, but my purpose is to test you. When three twos are multiplied, don't they become two times four? You know it if you memorize the formula. Already?"

"You can't test me like this, you clearly know that I can't turn my head around!"

After saying that, Li Lizhi immediately covered her mouth, not expecting that she would admit it before others said anything.

She is indeed not proficient in arithmetic, otherwise there would be no Wuqi 51.

But how could Li Lizhi admit defeat so casually? She immediately said: "Then you are so powerful and have the ability to compete with Li Chunfeng. Why are you showing off to me?"

Lin Heng was a little helpless: "I'm not showing off anything, these are all basics. If you don't believe me, ask your sister?"

Li Ningxi knew that if she nodded, Li Lizhi would be even more angry, so she just smiled and said nothing.

Li Lizhi snorted and ignored Lin Heng.

After the meal was finished, Li Ningxi and Li Ningxi also left. Li Lizhi kept muttering in her mouth, and Lin Heng was talking bad about herself without even thinking about it.

It's actually quite fun to tease him when you have nothing to do.

After about a half-hour break at noon, I have to continue my afternoon homework. Five hours a day, and a half-hour break at noon. After all, the day's work is quite busy.

In terms of math, by the Tang Dynasty, China's mathematics level had reached a certain level, and the Nine Chapters of Arithmetic, which had a profound influence on later generations of mathematics, had been born. As for the multiplication formula used by Li Lizhi, it had already appeared as early as the Spring and Autumn Period and the Warring States Period.

However, today's multiplication tables have a shortcoming. They are somewhat different from those of later generations, that is, they need to be memorized backwards.

Starting from 81, two two equals four and stops, which is extremely complicated to recite.

This is probably a cognitive problem. When you start memorizing from one to one, you will soon find the pattern, but reciting it backwards is a bit anti-human.

Moreover, there is a shortcoming in Chinese academics, that is, most of all achievements come from the accumulation of experience of the masses, and there is no scientific methodology.

As far as mathematics is concerned, the multiplication formula has appeared, but it is also an accurate result obtained by mathematicians after countless calculations. There is still no standard established for it, such as the differential application and comprehensive application of addition, subtraction, multiplication and division. This is mathematics. The most basic thing in the world.

This directly led to the fact that after China's achievements were spread to the West, they were quickly overtaken by the West, and even used these technologies to achieve higher and more amazing achievements.

Moreover, no one even knows about these achievements of China among the people, which is also a major drawback.

Therefore, Lin Heng's plan is to make a general classification of mathematics in the form of textbooks used when he was studying as much as possible, and then give it the standards it deserves to make it more clear in front of students.

With the ringing of the bell in the courtyard, schoolwork officially began.

"In this class, I'm teaching arithmetic. Everyone, please listen carefully!"

Upon hearing this, all the students immediately frowned.

"Prince Lin, counting is all learned by arithmetic students. Why should we learn this kind of thing?"

"Yeah, instead of wasting this time, it's better to talk about something serious."

In this era, there is still great contempt for mathematics and other knowledge, just like the contempt for businessmen.

Because the purpose of mathematics, in their eyes, is nothing but related to business.

This is exactly the situation.

Everything is of inferior quality, only reading is good. This so-called reading means studying Confucian classics, cultivating oneself, governing the country and bringing peace to the world, and serving the court in the future.Lin Heng didn't bother to explain. He came here to find a job instead of becoming an official. Why did he make himself so tired?
Mathematics is of little use. If you learn mathematics, physics and chemistry, you will go astray all over the world. Are you kidding me?
But to argue with people of this era is to play the piano to an ox.

You tell people that the earth is round, and they directly use the sage’s statement that the sky is round and the sky is round to criticize you, and you have no definite way to prove it.

Because the method you used to prove it is completely incomprehensible in this era, which proves that others think you are talking nonsense.

I won’t explain the explanation, just start talking.

He can still master basic mathematical knowledge, at least it is much more advanced than this era.

I'm telling you this, so just enjoy it secretly!

Lin Heng said directly: "If you don't listen, go ahead. I won't force you."

When everyone saw this attitude, they immediately became angry. This attitude was exactly the same as in the morning. Is their feelings really here to fool them?

listen!Why don't you listen? I want to see what you are talking about. If you really talk about something useless, at worst, I will go directly to Jijiu and file an anonymous lawsuit against you!
When Taixue lectures, the teacher usually speaks at the top, and the students listen at the bottom. They ask questions if they don't understand, and continue if they understand. They all follow the book.

Of course Lin Heng also has books!
Is it possible that the printing workshop is open for free?
After negotiating with Li Shimin, Lin Heng had roughly compiled a set of simple textbooks based on his own memory. The content involved was knowledge such as addition, subtraction, multiplication and division, square roots and square fractions. It was not much, but it was enough. .

Everyone immediately watched as Lin Heng took out a stack of textbooks from below and distributed them to everyone.

so generous?

After Lin Heng came up with the papermaking technology, the price of paper plummeted, and the price of books also dropped a lot. But even so, the price of a book was between five and ten guan.

Paper is just a carrier, what is really important is the content on it, and that is the value of the book.

But Lin Heng was in class and issued a book whenever he disagreed?
For a time, the students in the class had mixed feelings.

It turns out that Prince Consort Lin has never looked down upon them, he just used this method to stimulate their inner desire to win and make them learn!

Just like in the morning, although Consort Lin acted like he was here to waste his time, he gave them those shocking remarks. Just those four sentences made them feel a change growing in their hearts.

These things directly caused some kind of change in the hearts of these living beings who had almost been abandoned by Taixue.

When a bad teacher always looks at a student in a bad light, the student will feel very uncomfortable and respond with a worse attitude.

Even if they indulge in fun, why don't they expect someone to take them seriously instead of just treating them as a group of children who only want to have fun and enjoy themselves?

For a moment, everyone's eyes were full of longing.

Consort Lin seems to be a little different from other gentlemen!
Lin Heng, who noticed this look, couldn't help but be stunned for a moment.

Why do you look at me like this?Isn’t it just a few books?It's not worth the money.

Mainly for the convenience of class!

Then, some students opened the books, intending to see with their own eyes the books that Prince Consort Lin had prepared for them.

Without exception, everyone was stunned on the spot.

This... what is this?
Opening a page at random, what they saw were numbers and symbols that they couldn't understand, like a book from heaven.

Whether it’s Arabic numerals, addition, subtraction, multiplication and division, not to mention the arithmetic vertical expressions that will only appear after 1000 years.

Is this a calculation?

Does the number look like this?
How to learn this!
Lin Heng slowly said: "Classmates, let's turn to the first page. What is mathematics? Someone will read it aloud. It's just you..."
