Hearing Li Min's question, Cheng Chuliang took the lead and said: "Your Highness, I want to join the gang and do the damn thing! I have brought the money and people, and I am waiting outside the school. What you want us to do is just a word from Your Highness."
!”
Huo, can this guy talk? Do you think he is a gangster who dominates the mountain or what?
However, he was still very satisfied with Cheng Chuliang's ability to invest in the company.
Immediately afterwards, Yuchi Baoqi, Qin Hualiang and others expressed their willingness to invest in the company.
Moreover, they not only brought ten pieces of money, but each family brought at least ten people.
It can be seen from this that none of these old guys are good at each other, and their ideas are surprisingly similar.
And they are quite supportive of their business.
Of course, if there hadn't been a scene where Li Shimin showed off the Zhenguan table and Zhenguan chair, it's really hard to say whether they would have agreed to this.
After discussing this matter, it was time for afternoon classes.
When their arithmetic master Wang Xiaotong entered the classroom, all the students couldn't help but be shocked.
Huo, Master Wang Xiaotong didn't sleep all night, right?
His face was dull and tired, his eyes were red and bloodshot, but his spirit was surprisingly high.
After entering the classroom, Wang Xiaotong couldn't help but ask Li Min: "Your Highness, the answer to the question you asked yesterday was two hundred and forty-one and four feet?"
Hearing this answer, Li Min couldn't help but be surprised.
I really didn’t expect that Wang Xiaotong solved this problem in just one night?
Wang Xiaotong saw Li Min's expression and knew what he was thinking, and couldn't help but said: "I used stupid methods to calculate the answer bit by bit. In fact, I don't have a clue how to solve this question.
No. Your Highness, can you tell me your ideas for solving the problem?"
Problem-solving ideas?
Li Min was originally going to pretend that he didn't know this question, but seeing Wang Xiaotong's expression of thirsty for knowledge, Li Min couldn't help but soften his heart.
Li Min felt that if he didn't tell him the answer today, he might not be able to sleep well today.
Thinking of this, Li Min couldn't help but said to Wang Xiaotong: "Master, in order to solve this problem, we need to assume several unknowns. First, we can assume that the team's forward speed is X."
Just as he said this, Li Min's explanation was interrupted by Wang Xiaotong: "Your Highness, is Aix a magic horse?"
"Aix means-" Li Min took a deep breath, and then explained: "It means unknown, and I will temporarily replace it with Aix."
The next problem-solving ideas need to be described using graphics.
Therefore, Li Min walked up to the podium naturally, picked up the pen on the case, and began to explain to Wang Xiaotong on the draft paper.
"Master, you see, the team has advanced a total of one hundred feet. Divide 100 by the unknown number X, which is the time it took them."
"Huh? What do you mean by this calculation? What is this? What is this?"
In fact, after writing the calculation naturally, Li Min began to regret it.
Because he uses Arabic numerals and the use of addition, subtraction, multiplication and division signs.
But in the Tang Dynasty, these had not yet appeared.
To answer this question, we must first explain the meanings of Arabic numerals and various symbols.
Just explaining this would take a long time.
But now that it was written, Li Min had to explain it to Wang Xiaotong.
"Master, this is because when I was doing calculations, I found it too troublesome and inconvenient to write Chinese characters, so I used these symbols to represent numbers. You see, these are 1, 2, 3, 4, 5, 6, 7, 8
,9,0,use these ten numbers to represent from one to ten.”
"These symbols represent addition, subtraction, multiplication and division, for example, addition-subtraction*multiplication/division. Using these symbols to represent numbers is not only extremely simple and convenient, but also clear at a glance."
After listening to Li Min explain the functions of these symbols, Wang Xiaotong's eyes became brighter and brighter, and he almost jumped with excitement.
"Your Highness, that's great, you are really amazing! I would like to thank you for your contribution on behalf of arithmetic!"
"The meaning of these symbols themselves is much greater than this question! And the idea of solving the Aix problem proposed by His Highness has opened a new door for arithmetic!"
"Your Highness, please accept my respects from my master!"
After that, Wang Xiaotong bowed to Li Min respectfully.
Of course Li Min didn't dare to accept it and hurriedly hid aside.
This scene immediately stunned the friends below.
I have become a great Cao Cao, and His Highness the Sixth Prince is pretty awesome, right?
Will the master who deceived him with just a few words salute him?
Li Min asked helplessly: "Master, do you want to hear me explain this question to you?"
After hearing this, Wang Xiaotong came back to his senses and said quickly: "I think about it, of course I do."
Next, Li Min began to explain this question to Wang Xiaotong.
This time, the idea that Li Min explained to Wang Xiaotong was the linear equation of three variables.
Because the quadratic equation involves the square root problem, this is another difficult problem, and I can't explain it clearly in just a short while.
Well, it’s not that the explanation is unclear, but that Li Min only knows how to memorize a few square roots. As for how to take the square root, Li Min can’t remember clearly either.
Fortunately, Wang Xiaotong has a solid foundation in arithmetic, except that he does not understand some arithmetic formulas and needs to ask for advice.
In terms of problem-solving ideas, it is really easy to understand.
Not long after, Li Min finished explaining this question.
Wang Xiaotong, on the other hand, was dancing excitedly.
For him today, the harvest was really too great.
Not only did we get the numerical symbols, but we also got a new way of solving problems, assuming the unknown number X.
With these two tools, your arithmetic journey will surely reach a higher level!
Now, he has so many things to do that he can't even attend to class.
Therefore, Wang Xiaotong waved his hand and couldn't wait to dismiss the students from get out of class.
After class, Wang Xiaotong quickly wrote down these numerical symbols carefully to avoid forgetting them.
Next, Wang Xiaotong began to write memorials.
The emergence of these symbols is definitely an epoch-making change for arithmetic.
How can such an advanced symbol not be promoted nationwide?
Therefore, Wang Xiaotong couldn't wait to write a letter to the emperor.
First, he proposed that this symbol was proposed by the sixth prince Li Min. He praised Li Min fiercely and exaggerated his contribution to the sky.
Next, Wang Xiaotong introduced in detail the flexibility and ingenuity of this set of numbers and symbols in the memorial. With these numbers and symbols, arithmetic will surely usher in a new era.
In the end, of course, the emperor was asked to promote this set of numbers and symbols throughout the country.
