"Oh, if I had known this to be the case, would I have finished asking this question earlier? I really didn't expect that I made a miscalculation. Otherwise, I would be able to make Chu Tong so proud, huh..." Seeing Xiao Chenxuan stunned on the spot, Dong Ming squinted his eyes.

The novel murmured.

"Oh, time flies so fast! It's already half a stick of incense? It did take me a little longer." After Xiao Chenxuan finished speaking, he handed the paper on the table to Dong Ming. Xiao Zhe said: "Dong

Sir, the pheasant is twenty-seven and the rabbit is eleven, I don’t know if that’s right or not.”

Everyone around Dong Ming saw that the piece of paper that Xiao Chenxuan handed over to Dong Ming only had the words "lonely"! There was no calculation or anything like that. However, even if it was only on the paper,

Dong Ming was shocked when he heard the answer. Because these words clearly showed that Xiao Chenxuan had calculated the correct answer. No, the proud look on Dong Ming's face immediately froze.

"Have you seen this question before?" Dong Ming was stunned for a moment and immediately said with great certainty. Just now, Dong Ming didn't see Xiao Chenxuan doing any calculations at all! Otherwise, he would have written it on the paper.

How could I write the answer at the moment I wrote it? I looked at Xiao Chenxuan who was always stunned in place, how to calculate it, unless Xiao Chenxuan had seen this question before.

Dong Ming thought incredulously that if Xiao Chenxuan gave the answer after burning the incense or even longer, although he would be a little surprised, it would be within his tolerance, after all! Xiao Chenxuan could answer twice

The question he raised shows that Xiao Chenxuan is not comparable to ordinary people.

But for such a difficult question, Xiao Chenxuan could write the correct answer without any calculation. If someone told him that he could get the answer without calculation, Dong Ming felt that this person was definitely not a human, but a demon.

But Dong Ming really guessed wrong. In future generations, as long as primary school students who have studied the Mathematical Olympiad will be able to tell the answer to the question of chicken and rabbit in the same cage, there is absolutely no need to resort to cheating. After all, Dong Ming used this method

Isn’t it self-defeating to test Xiao Chenxuan with elementary school-level questions? How can Xiao Chenxuan become a senior engineer? It is not something that ordinary men in science and engineering can do.

"Haha, Mr. Dong, I don't know what is in your head. If you don't believe it, I will give you a chance to test the school's king on a few questions that you think are difficult to see if they can stump me.

Yeah!" Xiao Chenxuan curled his lips, quite disdainfully.

As the world's number one arithmetic master, Dong Ming is also considered a leader in the arithmetic community in this era. However, when Dong Ming encounters problems such as chickens and rabbits in the same cage, in most cases he follows the remaining records of "Sun Tzu's Algorithm"

The following method is used to solve the problem.

Without some calculations, it is very likely that the final answer will not be obtained. But the Xiao Chenxuan in front of him has not done the calculations at all, so Dong Ming feels that Xiao Chenxuan has seen the question he asked before.

Otherwise, even if Xiao Chenxuan is a god, it is impossible for him to write the answer the moment he picks up the pen! Therefore, Dong Ming thinks that if Xiao Chenxuan has never seen this question, then it is impossible for him to do this.

Following Dong Ming's shocked voice, in an instant, a huge sensation was caused in the entire banquet hall. After all, almost everyone present just now was sure that Xiao Chenxuan would not be able to answer. But in the blink of an eye, Xiao Chenxuan was naked.

At this time someone said.

"Oh, I really didn't expect it! King Ji of Chu State can actually solve this problem. It's not easy!"

"This is impossible! He just made it clear that

I’m at a loss for words, how could I just pick up a pen and write something out and be able to give the answer? This is incredible!”

"That's right! I don't believe it either. From my perspective, his answer must be correct!"

"It's easy to get it right! It's not necessarily true! How come we got it wrong? This only shows that he is a genius!"

"Yes! It's indeed surprising! But I still don't believe it!"

"However, if King Ji can write such an answer without calculation, either he has seen this question before, as Mr. Dong said, or he has something special! Otherwise, please explain it to him.

Wouldn’t it be nice if you explained it!”

In fact, if Xiao Chenxuan asked this question in ordinary times, everyone might not have such thoughts, but at this time, it is not only related to the face of various countries, but the most important thing is the prize of the Western Zhou Dynasty, which is a rare treasure since ancient times.

, who doesn’t want to win and take it back to his country to play? It’s so rewarding to do so!

But at this time, the six countries have lost the chance to win the prize, so they will naturally target the Chu State envoy. If you can’t get it yourself, why should you let Chu State pick it up? Therefore, if Xiao Chenxuan doesn’t say that he is

How to answer? Except for South Korea, the other five countries will naturally not give up their doubts about him!

Because of this "chicken and rabbit in the same cage" problem, there is no good solution in "Sun Tzu's Algorithm". If you are not a person who has reached the pinnacle in the field of arithmetic, it is really hard to figure out such a difficult problem.

Believe it!

"Oh? You want an explanation?" After hearing what everyone said, Xiao Chenxuan couldn't possibly say that he knew it in his previous life! Tell him that he had learned a linear equation of two variables! Besides, he still had to explain what a linear equation of two variables was, so

Xiao Chenxuan could only give a rough analysis of "Sun Tzu's Algorithm".

"Actually, this question is very simple! Think about it, a chicken has two legs and a rabbit has four legs. So, if the chicken and the rabbit lift their two feet at the same time, then all the remaining feet are

Rabbits, and each rabbit only has two legs, so the number of rabbits is half of the number of remaining legs, so we also know how many chickens there are! So, do you understand? In fact, "

There is a record in "Sun Tzu's Algorithm", but it is somewhat incomplete. Of course, I have also created another simpler solution. If you are interested, you can come to my country of Chu in the future, and I will definitely teach you, haha..."

"What? It's recorded in "Sun Tzu's Algorithm"?"

At this time, when he heard Xiao Chenxuan finished explaining in a few sentences, Dong Ming was stunned for a moment, and then he seemed to suddenly wake up, looking at Xiao Chenxuan with excitement, and what he just said, he also created a

A simpler calculation method? Is it true or false at this time? I am very old and have been engaged in alchemy and arithmetic for decades. I have found very few new methods for these difficult problems! But how old is Xiao Chenxuan?

Not only did he know a lot, but he also had comprehensive knowledge and was involved in everything. It seems that he forgot to study humbly after he achieved a little success! Thinking of this, Dong Ming spoke again.

"Your Highness King Ji, please wait a minute and let me understand first. Chickens have two legs, while rabbits have four. If each lifts two, only the rabbit's legs are left. Each rabbit has only one leg left.

Two feet, so the number of rabbits is half of the categories with remaining legs...and the number of chickens is the difference between the total number and the number of rabbits, it's...that simple?"

"What do you think?" Xiao Chenxuan didn't bother to answer Dong Ming and said perfunctorily.

Hearing Xiao Chenxuan’s words

, Dong Ming had just wondered where Xiao Chenxuan had seen such questions, but now, Dong Ming wanted to know how simple the simple method Xiao Chenxuan said was! No, Dong Ming didn't even want to show his face.

asked eagerly.

"Well, Your Highness King Ji, can you tell me how simple your simple method is? I really want to know."

As soon as Dong Ming finished speaking, everyone in the entire banquet hall turned their attention to Xiao Chenxuan, expecting Xiao Chenxuan to tell him the simple method he said.

Xiao Chenxuan shook his head and said: "Didn't this king say that you are interested in going to my country of Chu? I will definitely teach you. It is inconvenient and inconvenient to stay here."

The prince of the Liang Kingdom couldn't stand Xiao Chenxuan's pretentious look, so he said with a smile "Haha".

"Some people, I'm afraid they don't know how to do it at all! They can brag all day without fear of getting off their tongues."

After hearing what Prince Liang said, Prince Ning on the side also spoke.

"That's it, if you have the ability to say it, otherwise we will still suspect someone! That's because we know this type of question in advance. Otherwise, we all know this type of question. Without years of research, how could we answer it so easily."

Seeing everyone's disbelief, Xiao Chenxuan was helpless and had no choice but to pick up a pen and write on the paper on the table. However, his handwriting was indeed too unusual. After seeing it, everyone immediately burst into laughter, and some people kept whispering.

"Oh! If his method can't solve it, it's really unbelievable that he won four consecutive rounds!"

"Yes, yes! His wording is so unique, haha..."

Xiao Chenxuan ignored everyone and wrote: "There are x chickens and y rabbits. And each chicken and each rabbit has only one head; each chicken has 2 legs, and each rabbit has 2 legs.

4. Get: x+y=38 2x+4y=98 Solution: x=27 y=11 That is, there are 27 chickens and 11 rabbits.

The so-called chicken and rabbit in the same cage problem is actually a question of how many chickens and rabbits there are in a cage, how many heads are there on top, and how many feet are there below.

Common question types in elementary school Mathematical Olympiads, together with the problem of filling and draining a pool, will give countless children headaches in the future.

Originally, Xiao Chenxuan didn't want to cause trouble, let alone explain to this group of people what a linear equation of two variables is. But everyone didn't believe it and wanted to see their own method of solving the problem. Xiao Chenxuan had no choice but to use a linear equation of two variables to solve the problem...

In the previous life, this question might have been a little difficult for primary school students, but for any student graduating from junior high school, this is simply a question to get marks.

However, for people of this era, how does such a thing exist as equations?

Seeing the two unfamiliar symbols X and Y, as well as those tadpole-like Arabic numerals, not only the people in the banquet hall, but even Dong Ming was confused and had no idea what the hell Xiao Chenxuan was writing.

"What are these? I can't understand any of them."

"Yes! Just XX, and Shuya. What does it represent? And..."
