My servant in the Tang Dynasty is Li Shimin

Chapter 144 Three Questions, Wang Yuan Answers Instantly!

On the other side, seeing Wang Yuan's confident appearance, the little chubby Li Tai also worked up his energy, and his expression was unprecedentedly serious!
This time, if you don't succeed, you will be benevolent. He must get back all the previous humiliation!

In front of the eldest brother and younger sister, completely expose this deceitful big dog!
The eyes of the two met, and there was an invisible spark rising, both with unparalleled confidence.

At the opposite corner of the table, one was his master and the other was his younger brother. Li Chengqian, a scumbag in mathematics, could only tremble aside and dared not say anything.

Emma, ​​is there really someone in this world who is "strong" enough to use mathematics to compete?
He has lived for so long, and this is the first time he has seen such a thing, this is probably not the two gods!

"Wow! This is so good~"

Only Xiao Le'er didn't understand anything, she was watching the show all the time, and she was so excited that her little face turned red, she was so cute.

Because she understands that Prince Wang is about to start pretending.

Not long after, Wang Yuan left the hall with the three brothers and sisters, came to a side room, and sat down on a new table.

Moreover, he asked Uncle Ming to take the paper and pen, and handed them to the chubby Li Tai, signaling that he could come up with any questions.

Naturally, Li Tai would not refuse. He held a pen and paper, thought for a while, and then began to write.

Wang Yuan watched from the side, but his attention was not on the topic, but on the words written by Xiaopangdun.

I have to say that although this little chubby is very young, his handwriting is really beautiful. It can be seen that although Lao Li is not very good, he is still willing to spend money on his children.

No wonder this Li Qiu has the courage to compete with him in mathematics. It seems that he still has some real skills, but he doesn't know how long he can last in front of him?
"Master, the disciple has already written it."

While Wang Yuan was thinking, Li Tai had already filled the rice paper, and then handed it to Wang Yuan, showing a sly smile:

"However, I want to ask a lot of arithmetic questions this time. There are three of them. I hope you don't dislike them, master."

"Second brother, how can you do this? Didn't you agree to only ask one question?"

Before Wang Yuan could react, Li Chengqian became angry.

It was agreed just now that everyone will take turns to ask a question, why now Li Tai wrote three questions as soon as he came up?

What is this?

"Second brother, your heart is darker than Prince Wang's! Even dirtier!"

Xiao Le'er was also indignant, Wang Yuan blinked when he heard about it.

It's really nothing to complain about.

"Forget it, forget it, these are nothing."

He quickly took out some roasted seeds and handed them to the little girl, intending to gag her little mouth first.

If this girl is allowed to continue talking, maybe there will be some strange people and strange words.

Usually it doesn't matter to tear down the stage, but now he is trying to establish the image of a master, so he can't let this little girl make trouble.

Xiao Leer wanted to say something at first, but when she saw the roasted seeds and nuts, she suddenly burst into laughter and began to eat happily.

Wang Yuan then signaled Li Chengqian to calm down. Although the latter was reluctant, it was Wang Yuan's order after all, so he had no choice but to sit down.

"Three questions are three questions, just let the teacher help you solve all the problems at once."

Seeing the two shut up, Wang Yuan showed a confident smile again, full of "kindness".

Seeing this scene, Li Chengqian shuddered inexplicably, and brought up some terrible memories, and subconsciously gave Li Tai a "silent mourning" look.

Second brother, you have to go!
What the hell!

Li Chengqian's reaction made Li Tai shudder.

It's a pity that at this point, he has no way to retreat.

"Then Master, you have to look after it."

"Actually, these three questions came from Zhang Qiujian's Sutra in the Northern Wei Dynasty. Their solutions are actually recorded in the Sutra, but students always feel that it is not comprehensive."

"Therefore, I really want to ask the master who knows everything, I hope you can talk to me, master."

Although he explained the origin of the problem, Li Tai still had his own self-confidence and bit the omniscience to death.

In this era, every book is a luxury, and there is still a price but no market.

Although his master is rich, he really doesn't necessarily read the algebra.

However, what Li Tai didn't expect at all was that although Wang Yuan had never read Zhang Qiujian's calculation scriptures, he knew all the three questions on the paper.

This cannot be said to be a coincidence, it can only be said to have been "done".

This is simply not too familiar!
As his eyes moved down slowly, Wang Yuan's expression became more and more strange.

"Today there are ten grades of people, and for each one of them, the palace will give gold to them according to their grades."

"The top three come in first and get four catties of gold, and keep it out. The bottom four come in last and get three catties of gold, and keep it out. Those in the middle three who haven't arrived will also be given more in order. Ask how much gold each gets?"

In human terms, there are now ten idiots coming to grab money, and all of them are Li Er.

Because of the first-come-first-served relationship, the money that can be robbed by those who come later will gradually decrease.

The first three snatched a total of four catties of gold, and the last four latecomers snatched a total of three catties. Ask each idiot how much gold they stole from Li Er.

"Today there is a 320-mile Zhouzhan in Fengshan Mountain, and three people, A, B, and C, walk around the Zhouzhan together."

"A day travels 150 miles, a day B travels 120 miles, and a day C travels [-] miles. Ask how many days the trip will take."

In human terms, the three idiots circled around Li Er's palace at different speeds, and asked when these idiots would bump into each other and ascend to heaven together.

"One chicken is worth five coins, one hen is worth three coins, three chicks are worth one coin, and a hundred coins buy a hundred chickens. How much are the old man, mother, and chicks?"

In human terms, Li Er used 100 yuan to buy a hundred chickens and asked how many chickens, mothers, and chicks there were. He said that the taste was quite strong.

Although these three questions sound very simple, the meaning is very clear.

But it involves three knowledge points such as arithmetic sequence, finding the least common divisor, and ternary linear equations.

It has to be said that Li Tai is very capable in asking these three questions. The knowledge points involved are completely different, and it is difficult for ordinary people to answer them.

But that's all. For the people of Tang Dynasty, even if they are interested in studying mathematics, it may be the case that their level is dead.

It's not that they are too stupid, but because of the limitations of the times, what they see and hear limits their imagination.

Children who have never seen flying birds will never yearn for the sky. Behind any imagination, whether it is bright or dark, there will be its own basis and starting point.

Can really imagine out of thin air, most of them are crazy.

For Wang Yuan, although these three math problems are very good, they are still not worth mentioning in his eyes.

With his education background, even if he is given trigonometric functions and calculus problems, as long as they are not particularly difficult, he can easily solve them.

Not to mention arithmetic progressions, finding the least common divisor, ternary linear equations and other low-level mathematics.

They are basically the knowledge of the second grade of elementary school, anyway, the origin of all things is the second grade.

"Come here, Li Qiu, I will explain it to you now as a teacher."

Wang Yuan looked very confident, and waved for Li Tai to come over.

Hearing this, Li Tai was instantly stunned, and even had the urge to doubt his life!

It only took a few glances, and it was solved in less than ten seconds?
Even he, when he saw these math problems for the first time, he studied them for a long time.

Why now, this prince has an answer all of a sudden?
Want to teach him?

real or fake?

Although he was very skeptical in his heart, Li Tai walked forward obediently, sat next to Wang Yuan, and listened carefully.

It is not unreasonable for him to be praised by Li Shimin. Unlike Li Chengqian, he is actually very simple in heart, and he likes to focus on the things he likes.

Although he was a little disgusted with Wang Yuan before, he is still very serious when it comes to mathematics.

And Wang Yuan also swiped a pen, writing and talking directly on the paper.

"First of all, for the first question, let's assume that the first idiot took Li Erjia's gold, and each subsequent idiot will deduct the increasing second jin on the basis of the first jin."

"."

"Then the second question, first of all, ask for the speed of these three idiots, and then find their least common divisor, that is"

"."

"For the third question, let's assume that Li Er bought A chicken, B hen, and C chick."

Because Datang didn't have x, y, and z, Wang Yuan could only use A, B, and C instead.

He patiently explained one question after another step by step, listing all the formulas, and his tone was very relaxed from the beginning to the end.

On the other hand, Li Tai was stunned!
Why does every question have to be related to his father?

He was robbed again, blocked by a fool, and finally had to buy chickens.

Is his father a bit too miserable?
Li Tai suddenly felt a little sour, and had an inexplicable sense of substitution.

Li Chengqian even covered his ears, pretending that he didn't hear anything, only Xiao Le'er was still watching the play heartlessly, clapping his hands from time to time.

But Li Tai didn't mourn for Li Shimin for too long, and soon fell into deep thought.

Looking at the problem-solving method written by Wang Yuan, he frowned at first, then suddenly realized, and finally became more and more confused!
What the hell!

It turns out that these problems can still be solved in this way?

And it's all that simple!
Just relying on a few formulas, a few A, B, and C, can such a complicated problem be completely dismembered?

This is simply amazing!
You must know that when he first started to solve these three questions, he was like a fool, relying on his feeling, slowly substituting the numbers one by one to see which one was right.

This can't even be called stupid, it's just like mental retardation.

But now, Wang Yuan's problem-solving speed is at its peak, and his efficiency is tens of millions of times higher than before!
Wang Yuan was very serious, and filled three sheets of rice paper with the answers. After the ink was dry, he folded the three sheets of paper and handed them to Li Tai.

"If you don't understand it yet, I can explain it again."

Wang Yuan smiled, and Li Tai took the three pieces of paper and shook his head again and again:
"No need, master, what you said is clear enough."

"Before, the disciple was blind and offended the master. Please forgive me, master."

"Even if it is Zhang Qiujian, the author of this calculation book, his method of solving problems is not as clear and thorough as your master."

"Master, you are really a god in this world!"

Li Tai at this time was completely overwhelmed by Wang Yuan's talent.

He has rarely admired other people for more than ten years, but he is already convinced and admires this young man in front of him.

After finishing speaking, he carefully put away the three sheets of paper, fearing that they might be a little worn out, and planned to study them carefully after returning home.

Wang Yuan was lying on the chair, leisurely enjoying the admiration and gratitude of Lao Li's second son.

Not bad, boy, your road has widened!

The corners of Wang Yuan's mouth raised slightly, outlining a hint of a smile, which seemed kind and friendly, but Xiao Le'er, who was beside him, blinked his eyes wide.

Li Chengqian shuddered even more, before he had time to be happy for Wang Yuan, he fell into panic again.

He suddenly remembered the scene when Wang Yuan took him into the brothel that day, with such a smile and harmless temperament.

As a result, he passed out.
However, Li Tai, who was still immersed in the joy of gaining new knowledge, did not notice the approaching danger.

Instead, he took the initiative to lean forward and said confidently, "Master, now it's your turn to give me a question."

"Before I was too offensive, you can also ask me three questions."

"Need not."

Wang Yuan touched his chin, smiling all over his face:

"A well-arranged question is just a question, and it's fine if you can solve it."

After speaking, he swiped his pen and began to write quickly on the rice paper.

His calligraphy is different from Li Tai's, when he is free and easy.

The pen and ink flowed, and it didn't take long for Wang Yuanyang to write a lot of words.

Then when the pen and ink solidified, Wang Yuan casually handed it in front of Li Tai.

"Now, you can try to explain it."

"Gollum!"

Li Tai swallowed silently, and with anticipation and nervousness, he slowly picked up the topic and examined it carefully.

"Now, Li Er is going from Chang'an to Luoyang, with a total distance of 380 miles, and the left-behind department of Luoyang Dongdu will also send people to meet him."

The corner of Li Tai's mouth twitched, and it turned out that the protagonist was his poor father again.

"From Chang'an to Luoyang, Li Er's emperor's car can travel [-] miles per hour, while the carriage of Luoyang Dongdu Left Guards can only travel [-] kilometers per hour."

"If night rest and all other docking behaviors are ignored, at the same time as Li Er's departure, let a bird go with him at a speed of thirty miles per hour."

"When the bird encounters another carriage, it will immediately turn back and fly back and forth like this."

"Ask, when the two carriages met, how far did the bird in the middle of them fly?"

"This!!!"

The more Li Tai watched, the more stunned he became, completely dumbfounded!

"What the hell is this? Can't we just kill that broken bird?"

"Are you raising it for the New Year?"

He had obviously read it carefully, but Li Tai felt as if he hadn't seen anything!
What the hell kind of problem is this?Is that bird insane?
"It's not stuff, it's calculus!"

With a half-smile, Wang Yuan asked someone to pour a cup of scented tea, and drank it leisurely.
