"Listen, there are two kinds of animals in the cage, including chickens and rabbits, with a total of 36 heads and 108 feet. How many chickens and rabbits are there?" Hu Hai didn't even think about it, but just picked up a typical question of chickens and rabbits in the elementary school stage in later generations and told them.

After hearing this, Mr. Mikawa had a cold expression, but his hands were closed into his sleeves. Seeing his sleeves shaking slightly, he was obviously planning with his fingers inside. But for a moment, he was already a little impatient.

Everyone looked at the fine sweat gradually oozing out of Mr. Sanchuan's forehead and knew that it was difficult for him to solve this problem. Although scholars from several schools did not study arithmetics, they had also been exposed to arithmetics, and simple addition, subtraction, multiplication and division were not a problem. Now, after hearing the problem of chickens and rabbits in the same cage, they suddenly felt a big head.

Seeing that Mr. Sanchuan was probably unable to solve the problem, they were anxious for him. Han Fu was still smart and clasped his fists and said to Hu Hai: "This is a calculation of unknown numbers. In mathematics, it can be considered a difficult problem. Your Majesty can do it at will. It is so easy that it will be difficult to solve it."

Hu Hai looked at Han Fu's face with a single expression and smiled thoughtfully, "If I can come up with this question, I will definitely be able to solve it. Such a question is just a pediatrics."

When these words were said, the scholars in the hall opened their eyes one after another. They were not because of surprise, but because of resentment. It is true that Qin Ershi Hu Hai was the Supreme Lord of the Nine Five, but he spoke too timidly. This problem of ignoring the number of things is already the most difficult problem in calculating one's own. But in the mouth of this little emperor, he actually said so easily, as if their group of scholars were not as good as children.

Several people wanted to see what kind of solution Hu Hai could come up with. After solving this question, what more questions could be produced. If the emperor wanted to make things difficult for students all over the world based on just one or two questions, I am afraid that it would not matter whether the Qin Empire Academy would enter or not.

Feel the atmosphere of everyone. Except for Li Ke who was studying a paper sealing water on the other side, everyone was waiting for their own solution.

A smile was calm. Hu Hai waved his hand, and immediately two eunuchs were carrying a shelf with wooden boards. A thick layer of white paper was nailed to the boards. Hu Hai took a brush from the side, dipped it in a little ink, and carefully drew a chart...

Hu Hai first wrote a one in the column marked with chicken, and a thirty-five in the column of rabbit, and then marked the corresponding number of feet, and compared it with the number one hundred and eight...

After deriving for a long time, the answer to this question finally emerged on the paper. Eighteen rabbits and eighteen chickens.

Seeing Hu Hai deducing a large piece of paper, he deduced the question. Mr. Sanchuan all took pictures of himself secretly. Why didn't he expect such a simple method?

It was just that the emperor took half a quarter of an hour to deduce this question after deriving it, but it was said that it was a simple question in pediatrics, and it could be considered a slap in the face by himself. Which pediatrics question could allow an adult to deduce it for half a quarter of an hour?

Hu Hai looked at their faces and laughed and said, "The method I used is the stupidest and most straightforward solution to this question. Next, I will write the easiest method for you."

Hu Hai used the simplest arithmetic method to solve this problem.

"First assume that thirty-six are all chickens, and when minus 108, 72 feet, the remaining thirty-six feet are the two more rabbits. Except for 2 to 18, it is the number of rabbits, so the chickens will naturally know. It's amazing!" Mr. Sanchuan couldn't help but nod. Others saw Mr. Sanchuan nodding and knew that the emperor did have some research on mathematics. He didn't just use a problem of ignoring the number of things to fool them.

Hu Hai struck while the iron was hot and tore off the paper I just used. He said, "The two solutions just now are the most complex and stupidest, and the other is pure mathematical problem solving, which is the simplest method. However, I think both methods are not good. To learn one, not only should you solve the problem simply, but you should also understand intuition, which is the most beneficial to beginners. So I have another solution here."

As he said that, Hu Hai used a brush to draw a circle on the paper and said, "I'm now suppose that among the thirty-six numbers, there are rabbits as the circle, and the chickens as the thirty-six numbers minus the circle..."

Hu Hai said, while brushing, he used a circle instead of unknown numbers in the equation, and listed an equation on white paper.

When he wrote the equation on a blank paper, Xu Yi, a representative figure in the farmer, slapped his head and smiled: "This method is good. Use circles instead of a number, and list the calculation formulas in a simple way. It is simple and clear, and it is not difficult to calculate. It is indeed the easiest way to understand and not difficult to be a human being."

A simple problem of one-element equations made Mr. Sanchuan sweating, and Hu Hai couldn't help but feel sad for the basic education of the ancients. He wanted to change this, and he wanted to make the basic science of the Chinese nation the ancestor of this planet.

"Mr. Sanchuan, is my method fair?" Hu Hai asked with a smile.

"I have always been conceited and think that no one can surpass me except my junior brother Zhang Cang. I didn't expect that after being taught by His Majesty the Emperor today, I realized that there are people outside of others and there is heaven. I dare not call myself Mr. Sanchuan again, so I just want to call me a humble name. "Mr. Sanchuan was originally named Geng Shouchang, the ancestor of Geng Shouchang, a master of calculation in the Han Dynasty in the later Han Dynasty.

Even Gengzhi didn't know that a mathematician named Geng Shouchang would appear among his descendants. Hu Hai naturally didn't know that he was Geng Shouchang's ancestor. However, Hu Hai knew the junior brother Zhang Cang he just mentioned.

This person is an extraordinary person. In the Han Dynasty established by Liu Bang, he replaced Guan Ying as the prime minister and improved the master of mathematical science in "Nine Chapters of Arithmetic". If such a person could be used by the Qin Dynasty, it would be a great joy.

Zhang Cang is a wonderful person and never touches a woman who has given birth to offspring. If this person comes, he will definitely be able to play with Qin Mu.

One of them likes to play with mature women and the other likes to play with women who have not given birth, but they are a pair of wonderful people.

"Where is Zhang Cang?" Hu Hai couldn't help asking.

He clasped his fists and said, "My junior brother said that he should concentrate on arithmetics and not intend to enter the Imperial Academy. He believes that the world's arithmetics has reached its peak, and any breakthrough will start from others."

Hu Hai laughed and said, "This person is crazy. Since that's the case, I will give you some advice when I have time to ensure that you are studying one thing, so that Zhang Cang can't stand it."

He was slightly stunned and looked at Hu Hai with a suspicious face. He was obviously quite suspicious of Hu Hai's math.

"I won't let you doubt it, I'll give you a reassurance." As he spoke, Hu Hai took out a piece of paper, started writing on the paper, and splashed ink. The font was extremely ugly, but it made the straight eyes that were watching straightened instantly. (To be continued.)
