Game 6! Number! ”

In fact, the numbers in the six arts of Confucianism are also very close to reality, and they are divided into nine numbers, which are Fangtian, Corn, Difference, Shaoguang, Shanggong, Average Loss, Equation, Winning Short, and Side.

For example, Fang Tian, to put it bluntly, is to calculate the area of plane geometry, and the average loss is actually a reasonable apportionment of taxes; The decay technique was used to solve the problem of the reasonable burden of servitude, and a whole set of proportional theories including positive and inverse proportions, proportional distribution, complex proportions, and chain proportions were derived.

To know these things, the West did not understand them until the fifteenth century.

Therefore, some people in later generations thought that they could go sideways in the ancient mathematical world after learning a little bit of a quadratic equation or something, but they really underestimated the attainments of our ancestors in mathematics.

The Chinese are good at mathematics ... It's ancestral.

When it was the turn of mathematics, Lin Zhi smiled and stretched out his hand, hooked Cao Ang, and said with a smile, "Little Caozi, come, I'll pick one of the worst math in our place and compete with you." ”

Everyone looked at Cao Ang.

Yuan Tan clapped his hands and said, "That's right! Last time, my father also said that Ziyu helped solve the problem of military ration calculation, and the calculation speed is amazing! Zixuan, don't fall for the beauty trick, you have to fight for us! ”

"Oh? Xiao Caozi, his ability is not small! Lin Zhi turned around and said, "Who are the fools among us who took the first place in mathematics in the first two days of the test?" ”

A somewhat thin teenager walked out, he habitually scratched his head, and said hehehe, "Senior Sister Lin, it's me, but wasn't Su Bu's kid sick last time, otherwise I would have always been the second-to-last." ”

"This kid is Chen Xingxing, the worst one in our last math exam, as for how to compare... If I ask a question, which of you does it quickly and accurately, whoever wins, how? ”

"No! If he did the question you came up with, wouldn't we be at a loss? Yuan Tan immediately objected.

Lin Zhi snorted, "Who would be as shameless as you, then you have a question?" ”

The corners of Yuan Tan's mouth twitched, this... He really doesn't know how to.

"Rubbish!" Lin Zhi glanced at him, and the angry Yuan Tan wanted to hit someone.

"Listen to the question!"

Lin Zhi took out a piece of paper and wrote as he spoke, and Cao Ang and Chen Xingxing both sat down and began to prepare to write down the data.

"Zhang San has a workshop, the workshop produces a kind of iron tools, when the total income of making iron armor pieces is the number of A multiplied by 100 yuan minus the square of the number of A, the total cost function is 200 yuan plus fifty times the number of A plus the square of A, the local county officials are ready to collect taxes on the workshop, may I ask the county officials how much to tax each piece of iron, Zhang San has the largest income and receives the most taxes."

Lin Zhi casually said that Yuan Tan and the others were a question mark.

Sun Ce even raised his hand and kept wrenching his fingers.

This... Can it also be counted?

Before he reached sixty breaths, Chen Xingxing dropped his pen and said, "Okay! ”

Cao Ang hurriedly sped up the speed of his calculations, and after about twenty breaths, Cao Ang said, "I'm also done!" ”

Lin Zhi looked at the two of them and said, "Put up all your answers!" ”

Cao Ang and Chen Xing put up the paper together, and Yuan Tan and the others looked at the pile of things on the paper that looked like ghost drawings...

What is this?

"It's all twenty-five dollars, the calculation is correct, but Chen Xing's speed is faster, and we won!"

The Plains students immediately cheered.

"It's not! Wait a minute! Why is it twenty-five dollars? Zixuan, what do you write? Are they cheating? ”

Yuan Tan is really in a hurry, how can this be three to three.

If you lose the next game, won't you have to be the servants of this group of leaders?

Don't say ten days, even if it's one day, your father can beat himself to death when he goes back.

Cao Ang glanced at Chen Xingxing, he thought that he was good at self-study, but he didn't expect that even this so-called first-to-last fool could not be compared among the students of Pingyuan.

"It's me who lost, this problem is the simplest calculus, but it is to design a profit equation to calculate the vertex abscissa, and then substitute the abscissa into the tax amount equation, and then calculate the apex abscissa of the tax amount, just like counting fingers, but I usually see more and practice less, so the speed is too slow... Sorry guys! ”

...

Can you tell us something we understand?

Everyone in the Youth League felt that they might be a fool, otherwise why didn't they understand what Cao Ang said at all, what is called... Calculus?

"Don't be complacent! This is Sun Bofu, the son of Sun Changsha, with superb martial arts, which of you dares to try it with him? ”

The reason why Yuan Tan wanted to find Sun Ce was to let Sun Ce be a thug for him.

"Seventh inning! Fight!! ”

"Bo Fu, as long as you win, let's help your father intercede together, don't talk about military rations, you can do whatever you want!" Yuan Tan looked back at the crowd, "Did you say it?" ”

"Yes, yes, yes! As long as you win this game, we will intercede for your father together! ”

A group of officials in the N generation swore and cursed each other.

Hearing that it could solve Sun Jian's predicament of military rations, Sun Ce's fighting spirit suddenly soared.

"Wu Jun Sun Bofu! Who will teach? ”

Sun Ce stepped forward and took off his robe, revealing the energetic dress inside.

"Tournament? As long as it's from our academy, right? The corners of Lin Zhi's mouth curved slightly, revealing a wicked smile.

Cao Ang's face changed drastically, and just as he wanted to open his mouth, Lin Zhi's nose shrank, and his voice shouted with a crying voice, "Sister Qingcheng!" Someone is going to hit me!! ”

Hearing Lin Zhi's cry for help, Qingcheng, who had long been unable to hold back inside, immediately looked at Ma Qiang with his eyes.

Ma Qiang sighed, put down his pen and waved his hand, letting her play at will.

These girls are spoiled by themselves.

Qingcheng picked up a mace placed on the weapon rack outside, and shouted happily, "Lin Zhi, who bullied you!" Let me clean him up!! ”

Cao Ang saw Qingcheng rushing over with a gust of wind holding the mace, which might be heavier than himself, and wanted to kneel down on the spot.

He knew how powerful this sister was, he had seen this beautiful sister with his own eyes, and because the crows on the tree made her sleep badly, she threw the table to the tree...

"Sister Qingcheng! That's him! He said he was going to fight me, didn't he just want to beat me? Sister Qingcheng~~~"

Qingcheng came to move his muscles and bones, he looked at Sun Ce, although Sun Ce was only fifteen, but he ate well, and he was already one meter seven when the seedlings were good, which was a cut taller than Qingcheng.

"Choose your own blade, horse battle or foot fight?"

"Aunt. What is the girl? ”

"Ahem! This is Ma Pingyuan's wife Lu Shi! ”

Hearing that it was Ma Qiang's wife on the other side, everyone in the Youth League hurriedly tidied up their clothes and greeted them respectfully.

"Sun Ce, right? Brother Pony has said about you, saying that you have good potential, come on, pick up the blade! ”

Sun Ce was about to cry, how could he fight, fighting with Ma Pingyuan's wife, it was better to lose if he won.

"Where does the kid dare to do it with his wife... This.. Can you change it? ”
