"Scare" my high-achieving college students, if you can't even count this, what is it that makes people suspicious? Thinking of this, Zhang Xiao lightly rolled up his sleeves and said to Zhuo Qianya: "How can the level of a dignified master be questioned?" ”

Hearing this, Zhuo Qianya smiled and pointed to the fact that she had already calculated it last night, and thought it was extremely difficult to calculate. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info Sure enough, this temptation, Zhang Xiao divided five by two to match the data that Zhuo Qianya had worked hard to calculate for half a day. Zhuo Qianya looked at Zhang Xiao with admiration.

What you want is such an effect, such a look of adoration, Zhang Xiao secretly thought in her heart. Instead, Zhuo Qianya stood up and pulled Zhang Xiao to sit down very gently, but she stood aside and watched.

Zhang Xiao looked at him with a puzzled expression: "What does this mean?" ”

Zhuo Qianya smiled slyly and said: "Mencius has words, and those who are talented live in it. You can't come in person? ”

Shouting, the plot reverses faster! This is digging a hole for yourself. Zhang Xiao got up from his seat with a smile and said, "Suddenly, I remembered that there were still some things, Wei Jia was still waiting outside!" ”

After Zhang Xiao finished speaking, Zhuo Qianya's eyes glanced outside and said, "I found that he has more Yaxing than you?" Looking down at the Accord in the Zuichun Building, you can just see the soup kitchen, Wei Jia is really as leisurely as Zhuo Qianya said at the moment, and he is eating steamed buns with everyone.

Seeing this, Zhang Xiao patted his forehead with his head, this teammate is served!

Zhang Xiao couldn't avoid this when he saw this, and if he didn't hand over this method, he was afraid that he would be tired. Confucius didn't still say: There is no class in teaching, so I will reluctantly accept this female apprentice today!

Zhang Xiao picked up a piece of paper from the side and said, "If you want to calculate quickly, you have to replace the numbers with symbols to calculate." As he spoke, he handed the brush to Zhuo Qianya, and Zhuo Qianya asked suspiciously, "What are you doing?" ”

Zhang Xiao smiled and said, "You write down one to nine!" "Zhang Xiao can also roughly recognize some words now, and I am afraid that it will be ridiculous and generous for him to write Zhao Guo's characters!

After Zhuo Qianya listened, she held the pen and wrote it on the paper, and I have to say that the words written by Zhuo Qianya are full of pen strength and have the style of a master. Zhuo Qianya was just about to put down the pen, but Zhang Xiao stepped forward to hold it, Zhuo Qianya broke free and refused, but Zhang Xiao said: "Teach you how to write!" ”

Zhang Xiao held Zhuo Qianya's hand, wrote down the numbers one by one on the paper, looked at her and said, "Can you remember?" Zhuo Qianya is a show of wisdom, and after teaching it, she wrote it down independently, and looked at Zhang Xiao and said: "Look, this represents zero, this represents one, and this represents two......"

In the Spring and Autumn Period and the Warring States Period, it was empty to represent zero, Zhang Xiao just said: The symbol is more concise, but the empty number is more concise than the symbol, Zhang Xiao still explained to Zhuo Qianya for a long time? It wasn't until Zhuo Qianya compared it to herself that she said to herself: "Sure enough, the numbers are extremely convenient!" ”

Zhang Xiao saw that Zhuo Qianya could quickly write Arabic numerals, so she continued to draw four symbols on the paper and said: "These four are addition, subtraction, multiplication and division!" Zhuo Qianya glanced at it and wrote it down on the paper, and her mood was very cheerful, just like the novelty of learning a new knowledge when she was in elementary school!

During the Spring and Autumn Period and the Warring States Period, there was a strict decimal system of calculation and notation, and the ninety-nine tables for decimal multiplication and division were also invented.

In terms of computational mathematics, there were already four operations in the Shang and Zhou dynasties, and by the Spring and Autumn Period and the Warring States Period, the four operations on integers and fractions were quite complete. Among them, the "Nine Nine Songs", which appeared in the Spring and Autumn Period, can be said to be the crystallization of the combination of advanced decimal notation and concise Chinese Chinese characters, which cannot be produced by any other notation and language. Since then, "Ninety-Nine Songs" has become one of the most basic foundations for the popularization and development of mathematics, and it has continued to this day. It's just that the "Ninety-Nine Songs" in the pre-Qin period started from "Ninety-Nine Eighty-One" and ended with "Twenty-two as Four".

Seeing this, Zhang Xiao picked up a piece of paper and demonstrated it to Zhuo Qianya: "Look, this is the number you gave just now, it's calculated like this......" Zhang Xiao held Zhuo Qianya's hand and demonstrated it for her.

During Zhang Xiao's demonstration, Zhuo Qianya looked at Zhang Xiao's serious expression and said: Serious men are the most handsome, at this moment, Zhang Xiao's moment of explaining to Zhuo Qianya exudes this charm!

Neishi Shentu came to the Pingyuan Junfu after the early dynasty, and the Neishi of Zhao was in charge of state taxes, money valleys, and fiscal revenues and expenditures. Shen Di waited for a while before seeing Pingyuan-kun, and bowed: "Shen Tu has seen Pingyuan-kun!" ”

Zhao Sheng has a good acquaintance with Shen Di, and said in greetings: "Nei Shi has not been here for a long time, and I am afraid that I am here today not only to ask for a cup of hot tea." Hearing this, Shen Di almost overturned the hot tea he was drinking, and hurriedly stood up and said: "Shen Di can be the internal history, most of them were recommended by the prince back then, and Shen Di never dared to forget!" ”

Zhao Sheng laughed when he heard this, and hurriedly pulled him to sit down and said, "I, Pingyuan Jun, will never recommend people who are not talented!" ”

Hearing this, Shen Di sat down again and asked, "Prince, what is the soup soup in the city that the king said in the court today?" After hearing this, Pingyuan Jun patted him on the shoulder and said: "Under the whole world, it is not the king's land; On the shore of the land, it is not the king's minister. They are all king's people, and how can the king let them starve and freeze? ”

Shen Di listened to this and explained: "It's that the internal history is not well considered, but I don't know the deep meaning of the king. ”

After hearing this, Pingyuanjun was speechless, and picked up the tea and tasted it carefully......

They are all teaching others, Zhang Xiao's teaching is that the apprentices of the church starved to death of the master, Zhuo Qianya watched the demonstration a few times, and she was eager to try. At the beginning, Zhang Xiao was still teaching hand-in-hand, and when Zhuo Qianya learned, she said a few times: "Your hand can be loosened......"

Uh, this ...... It is quite simple to learn with Arabic numerals and arithmetic semiotics, but after Zhuo Qianya learned it, she completely devoted herself to the bamboo slip account book, but put Zhang Xiao aside!

Zhang Xiao smiled, I have become a special teaching staff? Just beside Zhuo Qianya watching the calculation, the accounts are not too big to calculate, often Zhang Xiao's mental calculation is calculated, but Zhuo Qianya is talented, and she still can't react for a while, even a few times, Zhuo Qianya put down the pen, and said angrily: "Besides, you will calculate it for me!" ”

Zhang Xiao smiled evilly when he heard this: "I like to calculate ...... like this" As he spoke, he gently grabbed Zhuo Qianya's slender waist, and held her hand with the other hand, ready to write and calculate?

Zhuo Qianya leaned forward, but Zhang Xiao, who was sitting next to her, was caught off guard, but Zhuo Qianya escaped, looked at Zhang Xiao and said, "I said it just now, and besides, you are ......."

Well, I think so! Without waiting for Zhang Xiao to say more, Zhuo Qianya walked out with the door closed, leaving an ignorant Zhang Xiao and a pile of account books......
