The math problem posted by Zhu Qi in Yingtianfu is a system of two-part equations written using Arabic numerals and mathematical symbols.

It can be said to be quite simple.

After all, Zhu Qi did not want to gather Western scholars to conduct research and exploration of advanced mathematics. He mainly wanted to popularize mathematical subjects.

The most convenient and popular thing at present is mathematics. If you say things like chemistry, physics, biology, etc., it requires a lot of preliminary preparations.

For example, chemistry requires extremely the blessing of materials science and physics.

It also involves a large number of operations, such as mechanics in physics.

In short, it is very unrealistic to want to blossom in the full range of natural sciences. Remember the science things that Zhu Qi learned when he was in school, because of the benefits of time travel.

However, it is too difficult and unlikely to carry out basic education in the Ming Dynasty to fully carry out these subjects.

Where did the large amount of education funding come from? The Ming Dynasty is still fighting against the Northern Yuan Dynasty.

At the end of the Yuan Dynasty and the beginning of the Ming Dynasty, everything was in trouble. The people finally had a better life. Will they be able to increase taxes?

As for commercial taxation, this is not something Zhu Qi can make the decision alone.

In short, promoting these disciplines is extremely complex. The best way is to pilot education on a small scale. With experience in pilot projects, it can be promoted.

Mathematics is very good, one pen and one piece of paper, and the little head turns all day long, of course it may be empty for a day.

After all, this thing is OK, it is OK, it is OK, it is not a joke for many heroes to hang themselves on the tree of high-level mathematics.

It is a little difficult, but mathematics must be promoted first. Whether it is the development of rational thinking or laying the foundation for future scientific reasoning and scientific calculations, this is all necessary.

Of course, people do not understand the importance of what Zhu Qi is doing now, and it is no less than that of going to the Northern Yuan Dynasty.

So when the first white-skinned eagle-hooked-nosed Semi-Mid-Eastern-looking Semi-Mid-Eye proposed that he would solve the question of His Highness of the Liao King, hoping to meet the Liao King and get the important things, the officials responsible for this time didn't care much about it.

I even felt a little despised by this Seminar. The official thought, this question was produced by our extremely smart King of Liao. How could you Seminar?

Especially when I saw the answer given by the Semi people, although it was very similar to the symbols written by His Highness the King of Liao, the official couldn't understand it at all, and thought to myself that it must be written randomly.

He did not scold the Semino person, but asked the man to leave his address and asked him to go back and wait for news.

This Seminister seemed to have not lived well in the Ming Dynasty, especially after the establishment of the Ming Dynasty, the division between Chinese and foreigners after the expulsion of Hu Yuan was once again the mainstream of society.

The Han people who have been oppressed for many years are naturally not very friendly to these Hu people.

The Seminister said some good things respectfully, hoping to meet His Highness the King of Liao as soon as possible and get some errands.

The official agreed and was about to report the matter, but then he met many student scholars who came to solve the problem.

It is said that His Highness the King of Liao wrote a book of heaven, and he is fighting a puzzle.

It is also said that His Highness the King of Liao actually wrote a painting.

Anyway, there are all things to say.

After all, Zhu Qi posted a notice that only one equation did not explain what this is. He did not know Arabic numerals and symbols, so he didn't know that this was a math problem at all.

This official was originally a literati, so he talked with the students and scholars. As he discussed, he put the answer of the Semen aside and forgot it.

Zhu Qi was still idle and had no news after waiting for several days. He took the initiative to go to the government office to inquire about the situation. Then he saw the answer written by the Semi-man on the table.

Zhu Qi picked up the answer and began to look carefully. The official next to him slapped his forehead, remembering that there was still such a thing that he had not reported.

Then he hurriedly said:

"Your Highness, this is the answer sent by a Semi person before. I am planning to deliver it to you, so you are here by yourself."

Zhu Qi didn't say anything, and read it from beginning to end, and there was nothing wrong with it.

In the fourteenth century, the development of Arabic numerals was no longer much different from modern symbols.

Of course, if Zhu Qi wrote a calculus, people nowadays would not understand it at all.

After all, calculus has not been invented yet, and it will take more than two hundred years to reach the 17th century, where stars are shining and hailed as genius.

The official originally thought that this erotic man was writing randomly, and His Highness would definitely not care, but he didn't expect that Zhu Qi nodded after reading it and said:

"Where is this person? You can let him come."

The official's forehead was sweating coldly and he hurriedly confessed that it was delivered several days ago.

Zhu Qi was a little amused and cried. Unlike modern times, he admired foreign countries and fascinated the foreign countries, the Hongwu period was really very Han and Tang style. Anyone who did not look like the people in the Central Plains was a barbarian, and the Han people became very confident.

Zhu Qi did not blame the official, but just asked the official to notify Semuren and report to the Institute of the Royal Entertainment Center as soon as tomorrow.

I also specifically reminded officials that if I encounter people who write such numbers and symbols in the future, no matter they are Han or Hu, they will all be called to report to the public.

Then he left with his hands behind his back.

The official did not dare to neglect it, so he quickly informed the Semi people.

As for telling Semu people in person, Zhu Qi felt it was unnecessary.

After all, it is just solving a system of equations. Now, in universities in the Western world, any college student can be solved by any college student.

If the other party was Newton, Zhu Qi would definitely greet him in person, but it was not.

We are the Prince of the Ming Dynasty, we are Party A, and the other party is Party B, so how can we ask someone in person?

The next morning, Zhu Qi came to the Royal Entertainment Center early, but he didn't expect that the Semino people came earlier than him.

Manager He came over and said:

"Your Highness, this semen came before dawn. It was cold outside. I didn't dare to freeze him, so I could only arrange a room for him to rest.

As a result, the Seminister drank a whole pot of porridge from me and said that she hadn't eaten for a long time."

Zhu Qi heard this and asked:

"He just drank porridge? Didn't you give him anything else?"

Manager He quickly shook his head and said:

"I know he is the guest His Highness is going to invite, so I naturally dare not neglect it. I also prepared some food, but he was unhappy to eat it."

"Why? Afraid of being toxic?"

"Not this, he said he was afraid that if His Highness looked down on him, he would have no money to pay."

Hearing Manager He said this, Zhu Qi nodded. It seemed that this person was not a person who was greedy for small gains, and it would be better to be honest.

Zhu Qi asked Manager He to call the person, but he went to the Royal Research Center of the Ming Dynasty. While inspecting the development of firearms, he was waiting for the Semi-sex person to come.

The hand-crank ink printing machine has entered the mass production stage, and with Zhu Yuanzhang gradually increasing his investment, he even opened a royal village specializing in ink printing machine in Yingtianfu.

Of course, this hand-crank ink printing machine will not be sold to the public. After all, in the early years of Hongwu, it was not like the middle and late Ming Dynasty, when the printing industry was relaxed, so that ordinary people could participate.

Zhu Yuanzhang, who is old in the world, is very careful in public opinion propaganda.

Not to mention printing books, even the books printed every year, those books are prohibited, and people are not allowed to collect them, etc., are clearly listed.

In addition to ink printing machines, Zhu Qi is most concerned about the improvement and development of firearms.

Now the landmines made by the local method have been created. Once the mines are captured, the landmines will be too simple.

As long as the gunpowder and striker are in place, you can install any things left.

If you make another box, no matter whether it is a tube or anything, anyone who steps on it will follow it into the box, but this box is just a relatively large one.

As for the power of landmines, pigs have been tested in advance. The effect is good at present, and everyone has eaten several meals.

Zhu Qi felt relieved when he heard this. As for the on-site test, there was no need for anything. The explosions in the main urban area of ​​Yingtianfu were probably going to be beaten to death by Zhu Yuanzhang.

However, the protagonist still felt that he was not at ease enough when he was fiddling with these gunpowder-related things all day long at the Royal Entertainment Center.

But there is no way. Who made Yingtian Mansion not his fiefdom? Zhu Qi could not make land around Yingtian Mansion.

After all, the household registration system is very strict these days. If the prince Zhu Qi dares to buy land in Yingtianfu, what is this called? This is called land annexation!

The reason for the destruction of dynasties in history is that the land of ordinary people is stolen by landlords and dignitaries, and only then will the rebellion be rebelled if everyone cannot survive?

During the Hongwu period, Zhu Yuanzhang clearly understood the reasons for the demise of the dynasty, which led to the military field system.

As for the military field, it is not the equal field.

So what is military fields? Explain that the fields that are distributed to military households and collected less taxes are collected, and these are military fields.

The military field has another more important attribute, that is, the military field, which is not owned by the military households. The master of the military field is the emperor!

In other words, military fields are land with state-owned assets.

Someone once did this, but failed. The man was called Wang Mang, who was known as the time traveler.

Zhu Yuanzhang was naturally not a time traveler, but he was still more thorough in his research on history, regardless of whether Zhu Yuanzhang was familiar with Wang Mang's specific policies on land reform.

But Zhu Yuanzhang knew that if the dynasty was stable, the people's land must be able to withstand it. At least those ordinary people who served in the army, that is, the military households who accounted for the vast majority of the Ming Dynasty, had to have land!

Zhu Yuanzhang originally intended to use this innovative system to ensure that land annexation is eliminated from the root.

What is the best way to merge military fields? They all have state-owned assets, which belong to the emperor. The emperor has an order that the general field can be distributed again without any reason. I believe no one will move military fields.

Zhu Yuanzhang had a good idea, but later history proved that there were policies above and countermeasures below.

The land that should be swallowed by military households is still swallowed by those who have become officials, and those who have become officials have become more corruption and have helped the officials to annex the land.

During the Chongzhen period, military household escape incidents became more and more serious, and all troops were vacant. Even military towns in Liaodong had a vacant salary ratio of 20% all year round, which was an unwritten unspoken rule.
