Chapter 457 Ye Xuan Can Be Called A Sage In This World!
Chapter 457 Ye Xuan can be called a sage in this world!
At this moment, many people admire Ye Xuan and even regard him as a god.
The original intention of the inventor of chicken and rabbit in the same cage was to give everyone a training method, but unfortunately, very few people could understand it, so that later on, it became a problem.
In addition, the reading atmosphere changed later, and during the Song and Song Dynasties, most of them paid attention to the classics and history collections, so no one cared about arithmetic.
Today's arithmetic, in Ye Xuan's opinion, has reached an extremely weak level.
Even if he is selected as a scholar or a scholar, his arithmetic ability will not be as good as that of the junior high school students of later generations.
Ye Xuan has long felt helpless about this. After all, it is related to the safety of the students who will become officials in the future.
If you don't stay up all night long to learn how to manage the world, then no matter how many books you read and no matter how good your articles are, you are just a fool, and any scribe can give them to your subordinate clan.
When Ye Xuan set the questions before, he added arithmetic and so on for this consideration.
However, others did not know what Ye Xuan was thinking. In their opinion, Ye Xuan might be deliberately making things difficult, or it was unknown whether this was the emperor's secret instruction.
It is no exaggeration to say that most of those who can attend lectures here today have the same mentality, that is, taking the opportunity to learn a thing or two, so that they will be more confident in the imperial examination in the future.
However, although this mentality has prevailed, there are still many people obsessed with arithmetic.
In their opinion, Ye Xuan's explanations are clear and simple, and compared with obscure classics, they are obviously easier to understand.
Most of these people have already had some understanding of arithmetic and have also studied arithmetic, so after listening to Ye Xuan's words, they were very enlightened.
After Ye Xuan finished explaining, he looked around at everyone and waited until everyone had digested it before he continued to speak.
He smiled and asked: "Everyone, is there anything you can't understand in my explanation?"
As soon as Ye Xuan said this, everyone looked at each other in confusion, and then they realized that no one was even remotely puzzled.
Even the most stupid person has a clear mind at this moment and understands Ye Xuan's knowledge points quite well.
Seeing that no one spoke, Li Wenhua asked with a smile.
"Master Ye, what is the name of your solution? If it spreads in the future, it would be nice to have an explanation!"
Ye Xuan thought for a moment and said with a smile: "Let's just call it the unknown! It's a solution anyway, and there must be unknowns in any solution!"
After hearing this, Li Wenhua nodded secretly and signaled others to take notes with his eyes.
He was really excited at the moment. He originally invited Ye Xuan to come, firstly to make friends, and secondly because he felt that Ye Xuan was really accomplished.
But what Ye Xuan said today is equivalent to filling in some blind spots in arithmetic, which is almost comparable to founding a sect.
As the inviter, he is naturally honored now.
Li Wenhua thought for a while and felt that Ye Xuan's theory could not only be this.
Now that you have shamelessly asked the other party to explain, there is no reason to give up halfway.
So he simply continued to request: "Master Ye, what if two or more unknowns appear at the same time, just like what you just solved?"
Ye Xuan also knows that if he wants to stop today, he must speak clearly.
So he simply waved his hand again, indicating to his servants to change the blackboard.
After a while, he brushed a few dots and wrote down a large area of text and the park.
Because there was no explanation, everyone could not see clearly. Those who were far away could not even see clearly what was written.
Just when they were wondering, Ye Xuan had already motioned for Li Wenhua to take a seat, cleared his throat and continued to explain.
"As you can see, in the question just now, there are two unknown numbers, but they are related to each other. It is like a mechanism that is linked to each other. One of them needs to be solved first. As long as one of them is correct, the other one will be solved. Ready to come out."
When everyone heard the words, they all felt that it made sense, and they all nodded quickly, secretly sighing inwardly at how easy and clear Ye Xuan's explanation was.
Ye Xuan, after giving them some time to react, continued.
"In this case, we have to think about how to turn the question into an equation, and how to make the equation true. This is what I call an equation."
Listening to Ye Xuan's words, Li Wenhua looked serious. He was about to ask why he was called so, but he couldn't bear to interrupt Ye Xuan's explanation.
The people below didn't care about their names at this moment, but thought about their own methods.
Ye Xuan seemed to want them to think, and when he spoke later, his speaking speed slowed down a lot.
He pointed at everyone and said: "For example, if we ask for the number of people inside and outside the venue, we must first know the total number of people as a reference.
Seeing that it was combined with reality, everyone seemed to be more serious. Li Wenhua was also secretly thinking and making assumptions.
Ye Xuan was silent for a moment, and then continued: "If this question is more complicated, I will list the students and masters equally as unknown numbers. I will only tell you the scores and the number of people in the internal and external venues, as well as the relationship between teachers and students. Situations, such as proportions, etc., how do you make formulas?"
After hearing Ye Xuan's words, everyone quickly thought and hypothesized in their hearts.
Not long after, someone actually figured it out, but he didn't rush to speak. Instead, he absorbed the rules Ye Xuan gave before, raised his arms, and waited for Ye Xuan to ask.
Seeing this, Ye Xuan smiled and nodded at someone, "That person quickly said what he wanted to say.
"."Sir, please don't laugh at the students' shallow opinions. The students feel that if they want to know the number of teachers and students, they have to make assumptions, that is, treat it as an unknown number, and then substitute it into the total number of people, or separate the number of people. "
Perhaps he was worried that Ye Xuan would retort. After the student said this, he looked at Ye Xuan again and saw that his face was calm and not displeased, so he dared to continue.
"Use the number of people to do multiplication, division or addition and subtraction. Find one separately as a reference, and then deduce the other one. I wonder what the students said, is it correct?"
Hearing this, Ye Xuan showed a trace of relief on his face.
He didn't expect (Qian) that the other party could apply what he learned so quickly, so he immediately gave a few words of disapproval.
After receiving Ye Xuan's approval, the student's face was naturally filled with joy, and others looked at him with a little more admiration and envy.
Ye Xuan sent the students to sit down and then continued to compose.
"Everyone has seen it. This is applying what you have learned. I think you should understand the truth. How to use it in the future depends on your understanding.
With that said, Ye Xuan planned to end the class, but before he could say anything, Li Wenhua spoke shamelessly again.
"Sir, we have just found one and two unknown numbers and solutions. However, these three are too difficult, and there will inevitably be mistakes. Why don't you explain them again to ensure that everyone can understand them? !”
After hearing Li Wenhua's words, all the students and even the master responded loudly, and for a while, there was a lot of noise inside and outside the venue.
