Datang: The prince of salted fish was overheard by Li Er

Li You picked up the pen and quickly wrote a series of symbols on the paper.

Wang Xiao went to look at the paper, but he didn't know any of these symbols.

Li Anren on the side reminded: "Teacher, these are the symbols in the test paper just now, used to replace the words."

Having said that, Wang Xiaotong also understood a little bit.

But although he understood the numbers, he still didn't know what Li You wrote.

At this time, if another modern third-year student came over, he would tell them that Li You was formulating a cubic equation in one variable.

Li You assumed that the same height and depth of the two granaries were unknown, and the sum of the two granaries contained 120 dendrobium, seven buckets and three liters as the equivalent relationship, and established a simple one-dimensional cubic equation.

This process is easy to say, but it is not small in practice.

For Li You, the biggest difficulty is converting the ancient units of volume and length into modern units of measurement.

If Li You's brain hadn't been systematically strengthened, perhaps he would have spent a lot of time on this step.

After this step, however, the rest is relatively simple.

Soon Li You solved the unknown number of height and depth as one foot five feet five inches.

After writing this answer, Li You was about to continue calculating the volume of the two warehouses, but was interrupted by Li Anren.

"What algorithm does the prince use?"

Li You's algorithm seems like a holy book to Li Anren.

But Li Anren can't help but admire Li Anren for being able to get the answer so quickly and accurately.

He and Wang Xiaotong had studied the question just now for a long time, but they didn't expect Li You to answer it so quickly.

Li You smiled slightly and said, "The method I just used was called solving equations. Your question is a bit complicated, so you used three-dimensional equations."

"In fact, equations have many wonderful uses. For example, the chicken and rabbit in the same cage in the first question just now can also be solved with equations."

As he spoke, Li You began to write and draw on the paper again.

But this time he wrote and explained.

"We can set the number of rabbits to X and the number of chickens to Y..."

After some explanations, that question was easily solved.

Li Anren was stunned, and stammered a little: "His Royal Highness Chu's method, is it something we can learn after we have learned it in the past?"

Although Li Anren was a little bit resistant to the new studies at the Shence Mansion at first, it was also because he felt that he would not be able to learn what he wanted to learn.

But now, after Li You opened a new door of mathematics to him, he wanted to get in even if he squeezed his head.

So after asking this question to Li You, he became a little restless.

He was very afraid that Li You would shake his head, that Li You would refuse to teach this method of equations.

But soon, Li Anren felt at ease.

Li You nodded with a smile and said, "Of course, in my teaching, equations are just the basics for getting started. In addition, I will also teach you more advanced and practical arithmetic knowledge such as calculus."

Hearing this, Li Anren finally felt relieved.

He turned his head and gave Wang Xiaotong an apologetic look.

But he found that Wang Xiaotong's eyes became sharper, and the whole decadent look just now disappeared completely, instead, he seemed to be ten years younger again.

Then Li Anren was dumbfounded.

Only Wang Xiaotong said: "King Chu, I wonder if the old man can go and listen in when these algorithms are being taught!"

Wang Xiaotong's enthusiasm for mathematics is no less than that of Li Anren. On the contrary, it is precisely because he has been obsessed with mathematics for many years that he can see the value of Li You's new method.

It is simple and easy to understand, and can express and solve problems very intuitively.

Taking another look at Li You's clear answering process, he found that using these symbols instead of words was indeed much clearer.

The effect of one or two numbers in the question is not obvious, but when it is put into the problem-solving process, the effect is quite different.

Wang Xiaotong also answered similar questions in his calculations.

But compared to the answering technique that is often hundreds of words, these symbols are too concise.

Wang Xiaotong did not expect that just now he despised the number symbols of the whole exam, but in the end it turned out to be one of the most subtle parts.

And now, he couldn't wait to learn.

In the face of learning, he doesn't think there is any problem in asking a child for advice.

There is no precedence in learning, and the master is the teacher.

Such a scholarly demeanor is fully demonstrated in Wang Xiaotong.

This question made Li You admire Wang Xiaotong a little more in his heart.

Wang Xiaotong, who has almost stood at the pinnacle of mathematics in the Tang Dynasty, not only did not get depressed because of a competition, but it aroused his enthusiasm for learning.

Li You replied happily: "Dr. Wang can come if he wants to. In fact, I also want to hire Dr. Wang as a visiting professor of our school."

"Dr. Wang's achievements in mathematics are obvious to all."

"The equation is just a new method of thinking. After time, Dr. Wang masters it well, and the arithmetic will definitely be more sophisticated."

Wang Xiaotong was also a little excited when he heard that he was able to attend the audition, and he also blushed slightly in the face of Li You's flattery.

"I'm ashamed, I'm afraid I won't be qualified for the position of visiting professor..."

Wang Xiaotong was about to resign, when suddenly a loud voice came from beside him: "Dr. Wang, you are my master of mathematics in the Tang Dynasty. If you are not competent, there will be no one in the world."

"Now I will appoint you as a visiting professor of Xinxue Mathematical Calendar, and at the same time, you will also be a Ph.D. in Mathematical Sciences of the Imperial Academy."

As soon as the voice came out, everyone immediately recognized Li Shimin who had come in disguise.

"Greetings, Your Majesty, and the Crown Prince!"

Immediately, everyone knelt down in the examination room.

Seeing Li Shimin coming, although Li You didn't kneel down, he bowed his hands and said, "I pay my respects to my father, my prince."

Seeing his prince show off the limelight and convince Wang Xiaotong, the leading figure in mathematics, Li Shimin was happier than he had grown up happily.

Li Shimin glanced at Li Chengqian beside him again, and said, "You'er, do your new study well, and help you select more talents for Brother Huang in the future!"

Li Chengqian also said obediently: "Fourth brother, I hope your new study will be better and better."

Li You didn't have any prejudice against Li Chengqian at first, everyone was brothers with blood thicker than water, so naturally he nodded in agreement.

This time, Li You was recognized by the teachers and students of the Imperial College, and even got a promotion in the quota of entering the new school.

Li Shimin said that anyone who Li You thinks has achieved the standard in the exam can enter the new school, and will no longer be restricted by the previous [-] people.

Hearing this, the scene was full of laughter.

Even the mathematics students who were a little neglected in the exam felt that they had a chance.

Li You is naturally the happiest. With this group of talents, he can accomplish many things within five years, and the heyday of the Tang Dynasty will be many years earlier.

Inadvertently, Li You noticed that Li Chengqian's eyes seemed to be looking at a certain place unconsciously.

He followed Li Chengqian's gaze, and a playful smile appeared on the corner of his mouth.
