"Alas, I knew that this was the case, and I would have finished this question earlier! I really didn't expect that it was the old man who miscalculated, otherwise, he would have made Chu Tong so proud, hum..."Seeing Xiao Chenxuan standing still, Dong Ming squinted his eyes and muttered.

"Oh, it's so fast! It's even past half of the incense? It did take a little longer for the king. After Xiao Chenxuan finished speaking, he handed the paper on the table to Dong Ming, and Xiao Zhe said: "Lord Dong, pheasant twenty-seven, rabbit eleven, I don't know if it's right or not." ”

Everyone around Dong Ming saw that on the piece of paper that Xiao Chenxuan handed over to Dong Ming, there were only a few words "lonely"! There is no calculus at all. However, even if there were only a few words on the paper, Dong Ming, who heard the answer, was shocked. Because, these words clearly show that Xiao Chenxuan has calculated the correct answer, no, the smug look on Dong Ming's face immediately froze.

"Have you seen this before?" Dong Ming was stunned for a moment, and immediately said with great certainty, I want to, just now, Dong Ming didn't see Xiao Chenxuan have any calculations at all! Otherwise, how could he write the answer the moment he wrote it on paper? Looking at Xiao Chenxuan has been stunned in place, how to calculate, unless, Xiao Chenxuan has seen this problem.

Dong Ming's heart thought incredibly, if Xiao Chenxuan gave an answer even longer after a stick of incense, although he would be a little surprised, but it was within his ability, after all! Xiao Chenxuan was able to answer the questions he raised twice, which shows that Xiao Chenxuan is not comparable to ordinary people.

But for such a difficult question, Xiao Chenxuan can write the correct answer without calculus, if someone tells him that he can get the answer without calculus, Dong Ming feels that this is definitely not a person, but a demon.

But Dong Ming really guessed wrong, the problem of chickens and rabbits in the same cage, in the future, I am afraid that as long as they are primary school students who have learned Olympiad mathematics, they can report the answer in one bite, and there is no need to cheat at all, after all, Dong Ming used this kind of elementary school difficulty question to test Xiao Chenxuan, isn't this self-inflicted? How can Xiao Chenxuan become a senior engineer, it is not something that ordinary science and engineering men can do.

"Hehe, Lord Dong, this king doesn't know what you have in your head, if you don't believe it, this king will give you a chance, looking for a few topics that you think are difficult to test the school king, see if it is difficult to stump this king!" Xiao Chenxuan pursed his lips, quite disdainful.

As the world's first arithmetic, Dong Ming is also the leader of the arithmetic world in this era, but when Dong Ming encounters problems such as chickens and rabbits in the same cage, in most cases, he also answers them according to the methods recorded in the remnants of "Sun Tzu's Algorithm".

If you don't do some calculations, you probably won't get the final answer. But Xiao Chenxuan in front of him had not been calculated at all, so this made Dong Ming feel that Xiao Chenxuan had seen this question from himself.

Otherwise, even if Xiao Chenxuan was a god, it would be impossible for him to write the answer the moment he lifted the pen! Therefore, Dong Ming thought that if Xiao Chenxuan had never seen this question, then it would be impossible for him to do this.

With Dong Ming's shocked voice, in an instant, there was a huge sensation in the entire banquet hall, after all, almost everyone present just before decided that Xiao Chenxuan would definitely not be able to answer, but in the blink of an eye, Xiao Chenxuan slapped everyone's face nakedly, and someone said at this time.

"Yo, I really didn't expect it! This king of Chu Guo Ji can solve this problem, it's not simple! ”

"It can't be! He was at a loss just now, how could he just pick up a pen and scribble to give an answer, this is too incredible! ”

"That's it! I don't believe it, but if I think it's true, his answer is correct! ”

"It's right! Not necessarily! Why are we wrong, this can only show that people are geniuses in the first place! ”

"Yes! It's surprising enough! But I'm still a little unconvinced! ”

"However, this King Ji can write such an answer without calculus, either as Master Dong said, he has already seen this question, or he has something special! Otherwise, wouldn't it be nice to trouble him to explain! ”

In fact, if Xiao Chenxuan made this question in normal times, everyone might not have such a mind, 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 it and bring it back to their own country to play? What a face-saving experience for this time!

But at this time, the six countries have all lost the opportunity to win the prize, so it will naturally target the Chu State Mission, and if you can't get it, why do you want your Chu State to pick up the leaks, right! Therefore, if Xiao Chenxuan didn't say how he answered, except for South Korea, the other five countries would naturally not give up their suspicions about him!

Because of this "chicken and rabbit in the same cage" problem, there is no very good solution in "Sun Tzu's Algorithm", if it is not for the person who has reached the peak in the field of arithmetic, it is really unbelievable to want to calculate such a problem!

"Oh? Want to explain? Hearing everyone's words, Xiao Chenxuan couldn't say that he knew it in his previous life! I also told him that I had learned binary equations! Besides, we have to explain what a binary equation is, so Xiao Chenxuan can only roughly analyze "Sun Tzu's Algorithm".

Actually, this question is very simple! You think, the chicken has two legs, and the rabbit has four legs, so if the chicken and the rabbit raise their two feet at the same time, then all the remaining feet are rabbit's, and each rabbit has only two feet, so the number of rabbits is half of the number of feet left, so we know how many chickens there are! Do you understand? In fact, it is recorded in "Sun Tzu's Algorithm", but it is a little incomplete, of course, this king has also created another simpler solution, if you are interested, you can come to my Chu country in the future, this king will definitely teach you, haha..."

"What? Is it recorded in "Sun Tzu's Algorithm"? ”

At this time, after hearing Xiao Chenxuan's explanation, Dong Ming was stunned for a moment, and then seemed to suddenly wake up, looking at Xiao Chenxuan with excitement on his face, and what did he just say, he also created a simpler calculation method? At this time, it is true or false, I am a lot of age, I have been engaged in practicing Dan and arithmetic for decades, and there are very few ways to find new ways to solve these problems! But how old is this Xiao Chenxuan, not only does he know a lot, but he also has comprehensive knowledge, and he has involved everything, it seems that he forgot to study humbly when he has a little achievement! Thinking of this, Dong Ming spoke again.

"Your Royal Highness King Ji, wait a minute, let the old man understand first, the chicken has two legs, and the rabbit is four, and each of them lifts two, that is, there are only rabbit's feet left, and each rabbit has only two feet left, so the number of rabbits is half of the categories with feet left...... And the number of chickens is the difference between the total number and the number of rabbits...... It's as simple as that? ”

"What do you think?" Xiao Chenxuan was too lazy to take care of Dong Ming, and said very perfunctorily.

Hearing Xiao Chenxuan's words, Dong Ming had just wondered where Xiao Chenxuan had seen this kind of question, but now, Dong Ming wanted to know more about how simple the simple method Xiao Chenxuan said was! No, Dong Ming's old face was gone, and he asked urgently.

"That, His Royal Highness King Ji, can you tell the old man, how simple is your simple method, the old man wants to know."

As soon as Dong Ming's words fell, everyone in the entire banquet hall turned their eyes to Xiao Chenxuan, expecting Xiao Chenxuan to say 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 Chu country, this king will definitely teach you a green bag, it is inconvenient and inconvenient to be here." ”

The prince of Liang Guo couldn't get used to Xiao Chenxuan's pretending appearance, and said with a smile.

"Some people, I'm afraid they won't be able to do it at all! I am not afraid to flash my tongue by bragging all day long. ”

Hearing the words of the prince of Liang State, the prince of Ning State on the side also spoke.

"That is, I have the ability to say it, otherwise I still suspect someone! That's because I knew this kind of question in advance, otherwise, I all know this kind of question, and how can we answer it so easily without years of research. ”

Seeing everyone's disbelief, Xiao Chenxuan was very helpless, so he had to pick up the pen and write on the paper on the table, but his words were indeed too unusual, everyone immediately laughed when they saw it, and some people kept whispering.

"Yo! If he can't solve this problem, he really can't believe that he has won four rounds in a row! ”

"Yes, yes! His character is too distinctive, haha......"

Xiao Chenxuan didn't pay attention to everyone at all, and wrote: "There are x chickens and y rabbits." and each chicken and each rabbit have only one head; Each chicken has 2 legs and each rabbit has 4 legs. Get: x+y=382x+4y=98 solution: x=27y=11, that is, there are 27 chickens and 11 rabbits.

The so-called chickens and rabbits in the same cage is actually a cage with chickens and rabbits, how many heads are on it, how many feet are below, and then ask how many chickens and how many rabbits.

The common question types of the Primary School Olympiad, together with the problem of releasing and filling a pool with water, will give many children a headache in the future.

Originally, Xiao Chenxuan didn't want to trouble, let alone explain to this group of people what a binary equation was, but everyone didn't believe it and wanted to see their own way of solving the problem, so Xiao Chenxuan had no choice but to use a binary equation to solve this problem......

In a previous life, this question may have been a little difficult for elementary school students, but for any student who graduated from junior high school, this is simply a question to send points.

It's just that for people in this era, what kind of thing is equation?

Seeing the two unfamiliar symbols of 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 he didn't know what the hell Xiao Chenxuan wrote.

"I can't understand any of these things."

"That's right! As for XX, and the tree, what does it represent? And also. ”

Hearing everyone's constant discussions, Xiao Chenxuan really wanted to say, a group of scum of the Battle Five, the masterpiece of the great gods, is something that mortals can understand?
