"Pheasant Twenty-Seven, Rabbit Eleven"

On the piece of paper that Qin Yong handed over to Zuo Mingqiu, there were only a few words that were so "lonely"!

However, even if there were only a few words, in fact, Zuo Mingqiu was shocked. Because, these words clearly show that Qin Yong has already calculated the correct answer.

"But he didn't do any calculations just now! But if that's the case, how could he suddenly write an answer now? Zuo Mingqiu thought incredulously in his heart.

It turns out that although he is one of the masters of "clear calculation" in this era, in fact, when he encounters problems such as "chickens and rabbits in the same cage", most of the time he also answers them according to the methods recorded in "Sun Tzu's Algorithm".

In fact, the solution method recorded in "Sun Tzu's Algorithm" is still relatively complex, so if you don't go through some calculations, it is very likely that you will not be able to get the final answer. But now, Qin Yong has just done this, so it's no wonder that Zuo Mingqiu is surprised.

In this way, he didn't just mention the pen in the calculus process at all, but wrote the answer directly! But how exactly did he do it? Zuo Mingqiu's heart was extremely incomprehensible.

"Mr. Zuozuo, this competition should be won by students, right?"

Cheng Mubai in the audience saw that Zuo Mingqiu suddenly fell into deep thought, and he didn't react for a long time. So he was in a hurry and urged Zuo Mingqiu to say.

Originally. He mistakenly thought that this competition was a game, but he had won!

It's no wonder, because when he was calculating this problem, he still had some of his attention on Qin Yong's side. And the result is that now, except for a certain period of time, Qin Yong gently picked up the pen and wrote a little word on the paper, and then there was no other action! Therefore, he naturally thought that Qin Yong would not be able to answer this question at all, so. Naturally, he couldn't wait to get Zuo Mingqiu's affirmative answer, and then he could start laughing at Qin Yong wantonly.

It's just that what he didn't expect was that the final result was much more than he expected. Because Zuo Mingqiu didn't say anything at all after listening to his question. Instead, they picked up all the notes on both of them and showed them out!

"Pheasant Twenty-Seven, Rabbit Eleven"

Qin Yong's notebook naturally only has a few words "lonely". But on the note paper handed over by Cheng Mubai, there are also a few words! This is actually the final answer of both sides, but the situation is completely different from Qin Yong's notepaper, that is, the notepaper handed over by Cheng Mubai is full of calculations.

It can also be seen from this how Cheng Mubai came up with this question! In fact, this is the most typical solution method recorded in "Sun Tzu's Algorithm". So when Zuo Mingqiu saw this, he still nodded secretly in his heart, this Cheng Mubai is indeed talented, not only good poetry. Even this "Mingxue" subject is equally solid! It's just a pity that he has now met Qin Yong, a demon who can be called a "genius". Therefore, his brilliance is completely obscured.

"Hey, see no! Then Qin Yong has already solved this problem? ”

"This, this can't be! Didn't he just be at a loss? But how do you get the final result right away? ”

"That's it, that's it! I don't believe it, but if I look at it, his answer must have been written by hand, right? ”

"Written by hand? But the answer of the talented man is exactly the same! ”

"What? If that's the case, doesn't it mean that Qin Yong really solved this problem? ”

"Ahh What a surprise! ”

With the public announcement of the "answer sheets" of both sides, those who have already done good things have already copied the answers of both sides, and then circulated them to various groups of people, and the result has naturally caused a huge "sensation".

Because, almost all the people present decided that Qin Yongna was bound to lose not long ago. But he didn't expect that the current result was that Qin Yong also answered this question correctly by the way, so naturally, he also had the opportunity to continue to answer the second question.

"How is this possible?"

When Cheng Mubai saw such a result, he was also completely "stunned"! Because he originally thought that as long as Zuo Mingqiu announced the results, then he would be able to humiliate Qin Yong immediately. But he didn't expect that the final result was that both of them answered the correct answer, so the anger in his heart that had been "suffocating" for most of the day could only continue to "hold"!

"It's all already true, what's impossible?"

Zuo Mingqiu was standing not far in front of Cheng Mubai at this time, so when he heard him talking to himself, he couldn't help but roll his eyes and think to himself.

In fact, as one of Han Zude's students, he also clearly knew the entanglement between Qin Yong and Cheng Mubai, but he was not very disgusted by it. Because there are some fights between young talents, which is a good thing, and it can promote their all-round progress.

However, he is disgusted with the so-called talents who are always unwilling to admit the truth after clearly losing, and even mess around in the end, because that is too unkind to be a scholar. Cheng Mubai played such a role in his heart at this time.

And speaking of which, in this competition, he Zuo Mingqiu was obviously biased towards Cheng Mubai's side when he came up with the question, because Cheng Mubai, as one of his students, had studied the "Sun Tzu Algorithm" with him since he was very early, so. The problem of "chickens and rabbits in the same cage" is naturally no problem for Cheng Mubai.

But. Qin Yong is very different. Because although Zuo Mingqiu vaguely knew from his teacher's mouth that Qin Yong's "arithmetic" level should not be bad, but he really didn't know which Cheng Dù was not bad! Even if Qin Yong had studied "Sun Tzu's Algorithm", he didn't know whether he had studied it, so he used this first question to study Qin Yong!

Because in his opinion. No matter how high the level is, it is necessary to lay a good foundation, and "Sun Tzu's Algorithm" is one of the foundations. What he wanted to see was that Qin Yong would be able to pass the first "qualification question" smoothly, and then when the second question came, that would be the real competition with Cheng Mubai.

However, he was able to come up with such an answer without calculus. That must be something outstanding! Well, let him explain! ”

After Zuo Mingqiu thought about it for a while, he made up his mind.

In fact, if this matter was normal, he might not have such thoughts. But this time, the doubts about Qin Yong on the scene were relatively loud. The second point is that he himself is also very interested in knowing what kind of method this Qin Yong has to do this!

Because, this "chickens and rabbits in the same cage" problem, there is no good way to solve it in "Sun Tzu's Algorithm". And he Zuo Mingqiu, although most of what he usually teaches in Hanshan Academy is poetry and songs. But in fact, he is also the main teaching task of the subject of "clear calculation". It's just that this teaching task is generally only for a small number of people within Hanshan Academy.

And this part of the people is basically from a merchant family, so they all have a lot of interests. Cheng Mubai, in fact, is also one of the students in this small group of "studying" and "Mingpiao" subjects. It's just that his main business is not to study any "clear arithmetic" subject, but to study at the same time as the major "Jinshi" subject, after all, they start a family but do business as their family business, so as the heir of the family, it is natural for him to learn such a little "clear arithmetic" subject.

"Oh? Want to explain? ”

When Zuo Mingqiu made his meaning clear to Qin Yong, Qin Yong's heart was "abrupt". Because the reason why he made this problem so lightly is entirely because he applied the method of solving the binary equation in later generations, but if the solution of the binary equation is to be explained, it is inevitably too complicated, because it involves modern mathematical terms such as "yuan" and "time", equality and inequality, etc., which is simply inexplicable. So, he simply abandoned this method altogether, and instead intended to switch to a more colloquial one.

Actually, it's very easy to solve this problem! You can think of it this way, because this chicken has only two legs, and the rabbit has four legs, so if the chicken and the rabbit both raise their two feet at the same time, then all the remaining feet belong to the rabbit, and each rabbit only has two legs, so the number of rabbits is half of the number of feet left, and the number of chickens also comes out! ”

"Uh, that, I said that, do you understand? Actually, this method is recorded in "Sun Tzu's Algorithm", how? None of you have read "Sun Tzu's Algorithm"? ”

Qin Yong said in the end, and suddenly said curiously. It turned out that this so-called solution was put forward by the teachers in order to make it easy for them to understand when he was in junior high school in the later world, and he also said at the time that this solution should come from a strange book like "Sun Tzu's Algorithm". And this strange book, isn't there still many people who will read it in this era? How is that possible?

"What? This method is recorded in the "Sun Tzu's Algorithm"? There is no such method on Coco's "Sun Tzu's Algorithm"! Wait! Could it be that the "Sun Tzu Algorithm" you are talking about is the original text of "Sun Tzu's Algorithm"? And not the late Tang manuscripts that are now circulating everywhere? ”

Zuo Mingqiu was slightly "stunned" after hearing Qin Yong's explanation, and then seemed to suddenly wake up, and Qin Yong said with excitement on his face.
