If Xia Qi's memory was correct, the term 'chicken and rabbit in a cage' was recorded in Sun Zi's Arithmetic. However, it was Great Qin now, and Sun Zi's Arithmetic was still quite some time away.
For Chun Yu Yue to ask this question, it meant that someone had already proposed the idea of sharing a cage with chickens and rabbits as early as the Spring and Autumn Period.
This was actually not surprising. Previously, when Xia Qi was doing business, he had encountered people who proposed the theory of cutting circles and Pythagorean shares. However, it had not become a system yet, so it was not widely spread.
From an objective point of view, the problem of chickens and rabbits being in the same cage was extremely simple for a modern person. Xia Qi did not give Chunyu Yue any unknown variables, but solved the problem in a more easy-to-understand way.
"Master, there are thirty-five pheasants and ninety-four rabbits. If you tie the rabbit's two feet, the chicken and rabbit will be seventy-ten. If you untie the feet of a rabbit, there will be seventy-two feet in total, and so on. If you untie the feet of twelve rabbits, there will be ninety-four feet in total, and there will be twelve rabbits and twenty-three pheasants.”Xia Qi organized his thoughts and used a method that the people of Qin could understand.
The method was called the foot-binding method, which meant that the rabbit's legs were bound.
In fact, it was equivalent to the exchange of y and x in the equation.
The question of chickens and rabbits being in the same cage was originally raised by Chunyu Yue's disciple, Shu Suntong. After pondering over it for a long time, he asked Chunyu Yue for help.
Chun Yu Yue spent a lot of effort before he finally got the answer.
Chunyu Yue had only asked Xia Qi to make things difficult for him when he saw that Xia Qi was distracted in class, but he never expected Xia Qi to solve it so easily.
One had to know that he had used two days to push it out bit by bit.
Xia Qi's train of thought was completely new, so much so that Chun Yuyue deliberately made things difficult for him, causing him to end up in a bad situation.
However, Chunyu Yue didn't say much and tried to conceal the shock in his heart to ease his mind.
Xia Qi was a businessman, and he was sensitive to familiarity!
"Sit down! Don't be distracted in class!" Chunyu Yue said solemnly.
Xia Qi didn't have the brain to argue with Chun Yuyue. He was the one who was distracted first, and now that Chun Yuyue had raised it up high and put it down gently, there was no need for him to hold on to someone else just because he had untied the chicken and rabbit cage.
He was a businessman! Harmony breeds wealth!
Chunyu Yue's questions were mostly easy to understand. Most of them were based on counting sticks. At the end, he also gave some homework.
Numerancy had always been considered one of the six arts of a gentleman in the scholarly faction, so Chunyu Yue was actually quite attentive to teaching it.
After the class ended, the princes scattered like birds and beasts!
Huhai, who was still talking about his elder brother yesterday, had already run off to somewhere. The good young master, Fu Su, was still kneeling on the spot and thinking about his homework. Only the young master Gao, who was quite friendly before, was still beside Xia Qi.
"I have to think of a way to leave the palace!" Xia Qi sat on his knees and frowned.
It was not that he wanted to run away. The main thing was that he had entered the palace now, and the opportunity to go out was too rare. Moreover, he had already agreed on a date with Zhao Man. If he could not leave the palace, he was afraid that he would make her wait anxiously.
Even if he couldn't leave the palace, he had to find a way to send a message.
Seeing that Xia Qi hadn't left, Gongzi Gao, who was standing at the side, pondered for a moment and said,""Brother, why don't you come to my place?”
Gongzi Gao and Xia Qi were of the same kind, born to be businessmen.
It was just that Young Master Gao was born in the royal family, and Brother Zheng didn't like it, so he didn't have a chance. However, this didn't stop Young Master Gao's love for business.
Therefore, when he found out that Xia Qi, the richest man in the world, was his brother, Gongzi Gao had already become a loyal fan of Xia Qi.
"Alright!"
Xia Qi was also confused about the Imperial Palace now. He could not even take the opportunity to sneak away. With the young master leading the way, he could be considered to be familiar with the Imperial Palace.
Childe Gao was delighted when he heard that. He held Xia Qi's hand and stood up!
This was the bad thing about this era. The two men would shake hands with each other at the drop of a hat, mainly to show their closeness.
It was the core skill of the Emperor, Hand in Hand!
However, Xia Qi had been doing business for a long time and was used to this custom, so he did not mind too much.
With Young Master Gao's guidance and explanation, they finally had a certain understanding of the Great Qin Palace.
Great Qin had never been extravagant, so the Imperial Palace was quite simple and not that big.
To be fair, the Forbidden City that Xia Qi had visited in his previous life was even bigger than the Great Qin Imperial Palace.
Although it wasn't that big and wasn't luxurious enough, it was simple and grand.
This was a feeling that was hard to describe. Perhaps it was the temperament that Old Qin was born with.
Every flower, grass, tree, and leaf in the palace revealed its simplicity!
Although it wasn't vast enough, it was deep enough!
It was a pity that such a good place had been burned down by that silly Xiangyu!
Young Master Gao was talking non-stop about the Great Qin Imperial Palace while chatting with Xia Qi.
Little did they know that Xia Qi had already found out the general number of guards and vacancies in the Great Qin Imperial Palace through his interrogation.
The pattern was broken!
After tactfully rejecting Young Master Gao from eating with him, Xia Qi went out alone.
What evil intentions did Gongzi Gao have? He only helped me familiarize myself with the palace!
Xia Qi originally thought that there would be some second layer of protection or some hidden sentry, but he actually climbed over the wall with ease. Xia Qi also secretly thought that he had been alarmed for nothing!
Standing in the corner of the palace, Xia Qi took a deep breath!
"Go and see Zhao Man as soon as possible and tell her the whole story! Then try to come back before dark!”
Not long after Xia Qi left, Brother Zheng, who was handling government affairs in the palace, raised his head.
"Watch where he goes and who he talks to! If they had any intention of leaving the city, bring them back immediately!”
Dun Ruo, who seemed to be hiding in the darkness and controlling the Black Ice Platform, silently accepted the order!
