In the first class of this school, Yang Hao did not give too much scientific knowledge to everyone, but instilled some materialist ideas into these officials in his own way.

Daqi is not a seminary, nor is it for the study of ethics.

The only purpose is to cultivate practical talents, so that they can quickly put into work and become a brick for the construction of Daqi.

Yang Hao knew that in a short period of time, it would not be obvious for these people to give up their previous cognition, but only to imperceptibly affect them in the future.

Let them slowly embrace new habits.

As for what Yang Hao, the people of Daqi, think, Yang Hao didn't care at all.

People not only have a heavy nature, but also have the habit of imitation.

The top of Daqi accepted Yang Hao's ideas, and under the influence of the top down, it was only a matter of time before the concept of ordinary people changed.

The right to speak is in the hands of those in power, and the questioning of a few fart people cannot affect the overall situation at all, and will only be regarded as fools.

Throughout the ages, nothing more than that.

The officials came excitedly and left with mixed feelings.

Yang Hao didn't know how much the ones he said today could affect them, this first step had already been taken, just waiting for this seed to take root and sprout, blossom and bear fruit.

For the next period of time, the officials would go to the school on time every day to listen to Yang Hao's lectures.

Except for the first day, when he said something unrelated to knowledge, Yang Hao did not mention the idea of materialism again in the past few days, as if the events of that day were just an illusion.

Learning knowledge is a slow process, there are not enough teaching materials, and Yang Hao teaches no rules.

In terms of words, it's basically thinking about what to teach.

As for arithmetic, these officials have basically mastered the four operations, and what Yang Hao can do is to strengthen their practical ability by coming up with some questions.

Like, the question that drives all officials crazy at this time.

I don't know if Yang Hao deliberately disgusted them, or if he really had the intention to test them.

Even Shao Yan, who has the highest attainment in arithmetic, pulled out several hairs, and wondered why the chicken and rabbit were locked in a cage, isn't this an idle egg?

What's even more annoying is that I don't know how many rabbits and chickens, I only told the head and feet, how the hell do you know the answer.

Maybe this shit-like question, Yang Hao definitely came up with it to deliberately make things difficult, and the answer is that there is no fucking answer.

It's not just Shaoyan who thinks so, most of the people present think so.

It has been nearly an hour since the topic came out, and many people have written and scribbled and scribbled on the sandbox, and it has been bleak.

Yang Hao also thought that they could know the answer, and this question was just to get them used to thinking on their own.

After all, this kind of problem is already a very difficult mathematical problem.

Yang Hao smiled: "What? Has anyone figured it out? ”

Everyone was silent, with a bitter face.

"Chief, this question is too difficult, can this really be calculated?"

Yin said in a deep voice.

Yang Hao smiled: "Naturally, it can be solved, using the addition, subtraction, multiplication and division you have learned, it is not a problem to calculate this problem at all." ”

"My subordinates are stupid, and ask the leader to tell us how to solve this arithmetic."

Shaoyan scratched his head with a look of anticipation.

Yang Hao nodded, and those copper knives were carved on the wall behind him.

"The question is actually very simple, I said before,

There were an unknown number of chickens and rabbits in the same cage, thirty-five heads when counted from above, and ninety-four legs when counted from below. Q: How many chickens and rabbits are in each of your cages?

That's it! ”

Yang Hao asked.

For this question that has tormented them for a long time, everyone estimated that they would never forget it in their lives, and hurriedly said yes.

Yang Hao explained while writing: "We can think of it this way, if the cage is full of chickens, and the chickens have two legs, then the total number of legs is the number of two heads, that is, seventy legs.

In my question, there are ninety-four legs, and by subtraction, twenty-four legs are missing.

We also know that rabbits have four legs, two more than chickens.

Then the remaining twenty-four legs must be rabbit's.

We divide twenty-four by the remaining two, which is the number of rabbits.

Knowing the number of rabbits, don't you know the number of chickens?

”

Although Yang Hao explained in detail, everyone looked at the numbers on the wall and frowned.

Yang Hao sighed when he saw this, so he could only draw a rabbit and a few chickens on the wall, and explain them again in the form of pictures and texts.

Combined with Yang Hao's previous explanation, the crowd suddenly realized.

"It's amazing, it's amazing."

Shaoyan said excitedly.

Yang Hao smiled: "Yes, this is the magic of the way of arithmetic, as long as you flexibly use the knowledge you have learned, you can solve many problems in life."

Whether it is the Ministry of Officials or the Ministry of Household and Industry, it will make it much easier for you.

”

Yang Hao did not continue to speak, but let them figure out this classic mathematical problem repeatedly.

As long as they study this question clearly, their arithmetic level is at least, and they have reached the level of the first grade of primary school.

This kind of ability is already a high-level intellectual in this era, and in any tribe, if you can fool around, being a priest is definitely more than enough.

The sky is getting dark, everyone is still having a heated discussion, and Yang Hao is very pleased with such a warm learning atmosphere.

Thinking that when he used to go to school, he slept on the table, Yang Hao felt a little that he was really in the blessing and didn't know the blessing, with such good conditions, the thirst for knowledge was not as good as the ancients thousands of years ago.

Yang Hao opened the door to the world of mathematics for them, and the way of arithmetic will play a pivotal role in the development of the Daqi tribe.

At the same time that Yang Hao was teaching the civil officials of Daqi, boys between the ages of six and ten in Chang'an City were forcibly gathered.

When Yang Hao was not lecturing for officials, the Daqi Junior School belonged to them.

The officials at the bottom became part-time gentlemen, and the people who were chosen as gentlemen, in their hearts, were refused, for men, who wanted to stay with a group of little kids every day.

It's just that Yang Hao promised them that as long as they were gentlemen, they would add five catties of rice and ten eggs per month on the basis of Yulu, which made it difficult for these officials to accept this job.

It's just that although they are civil officials, this article is only relative to this era.

If you look at it from the perspective of hundreds of years and thousands of years later, they are living martial artists.

And how can these martial arts civil officials have such a good temperament to teach patiently, as long as they don't listen carefully, or the extremely simple questions are not answered, it is a murderous corporal punishment.

Slowly, the murderous reputation of these gentlemen can even stop children from crying at night.
