Traveling to Tang Dynasty

Guozijian is not someone who wants to go up, just like Guozixue and Taixue, your family is not an official above the fifth grade, and you don't even have the qualifications to enter the door.

This is also the door to calligraphy and arithmetic, which is open to the common people, of course, the premise of opening up is that your grades must be good.

The carriage staggered all the way to the company. Qianyuan has already inquired, and there is an exam before admission. There is no need to deliberately write wrong, and a thousand yuan will definitely not pass. Those who are also the same, a thousand yuan will not be one, and it is impossible to get in.

got out of the carriage and walked into Guozijian, and Qianyuan saw from a distance that there were several people standing outside the gate of Guozixue. One of them recognized Qianyuan at a glance, isn't this Wanyan girl, the long sword on her waist, Qianyuan is very familiar.

Qian Yuan stopped and thought for a while, Wan Yan is a guard, what is she doing in the country? Could it be that the heir of King Qin is studying here

I love to learn! People just want to live to learn all the time, I have decided to learn this, I said! Qianyuan hurriedly urged Steward Su to go faster.

The

plan did not change quickly, but the plan changed, and the question followed, how can I successfully pass the exam? This thing is obviously not something that can be learned in a day or two, after a little thought, Qian Yuan moved his eyes to arithmetic, this arithmetic should be the most likely to pass the exam, right?

The housekeeper arched his hand and said: "Hui Gongzi is a four-door study, my grandfather wants Gongzi to familiarize himself with Confucian classics, and hopes that Gongzi will become famous in the future and benefit the people." "

Qian Yuan thought to himself, Confucianism governs the world of fart, what kind of wall to steal light, lying on the ice for carp, who believes this thing, then he definitely has that serious disease in his head, or the kind that can't be cured.

Wang Qianyuan pretended to be a master and asked, "Can I choose by myself, I like arithmetic." Have you ever heard a saying, if the sky does not give birth to my Wang Qianyuan, arithmetic is like a long night!"

\

The housekeeper was stunned, and said with some stumbling: "Childe, this. I'm afraid that's not right. If you are the head of the house...."Before the housekeeper finished speaking, he heard a man's voice behind him: "How can you be so arrogant, my country's son and prison student, you have to study with an open mind, you are from that academy." "

Qianyuan turned around and said embarrassedly: "I haven't enrolled in school yet, are you?"

"The old man Wang Xiaotong is a doctor of arithmetic in Guozijian. "

Isn't this a brag x meeting the main owner? Qianyuan put on a smiling face and said, "Sir, I just had an argument with the housekeeper, I want to learn arithmetic, and he wants me to learn Confucianism." Confucianism is not as interesting as arithmetic, you say?"

Wang Xiaotong nodded, and shook it quickly: "There is no difference between high and low in what is learned in the world." Since you boast that you are good at arithmetic, I will test you, if it is really as you said, you don't need to take this exam, and the old man will allow you to enter arithmetic. "

It was really sleepy that someone sent a pillow, and Qianyuan said happily: "Please ask Mr. to ask the question." "

Wang Xiaotong said: "There are 33 businessmen, each staying in the hotel has three Wen, ask how much the store is?".

Qianyuan glanced at Wang Xiaotong, and his eyes seemed to say that you are serious, and he opened his mouth and said, "Ninety-nine Wen." "

Wang Xiaotong was slightly stunned when he heard this number, and sighed in his heart that although this is not a problem, it is the first time he has seen the answer so quickly.

Wang Xiaotong asked again: "Today, there are 14 horizontal steps in the field and 12 steps in the vertical, and the question is the geometry of the field

?"

Fourteen times twelve? 1,000 yuan didn't even think about blurting out: "One hundred and sixty-eight steps." "

Wang Xiaotong came with interest and then asked: "There is a round barrel today, fifteen feet in circumference, four feet in diameter, and five feet in height. Q: How much water is contained?".

Oh, this is the strength, Qian Yuan picked up a stone, made a formula on the ground, and soon got up and replied: "Two hundred and four." "

Wang Xiaotong said: "Although you answered quickly, it is a pity that you answered incorrectly, it should be one hundred and ninety-five. "

Qianyuan was a little confused for a while, thinking that it was πr2 multiplied by the high, and it was impossible for my physical education teacher to lie to me. I squatted on the ground again and counted again, and found that there was no mistake.

The heart said that today is the arrival of the king of heaven, and it is also two hundred and four! Qianyuan arched his hand and said: "Sir, slow down, please listen to me." "

Wang Xiaotong: "Oh, please. "

Qianyuan said with a straight face: "I'm not afraid of arithmetic, and I will know if it's right or wrong." Since you and I have calculated two numbers, there must be one person who is wrong, and if you find a carpenter, make a barrel according to this specification, fill it with water, pour it into a measuring device, and you can distinguish right from wrong. "

After hearing this, Wang Xiaotong agreed very much, and said: "A good sentence of arithmetic is not afraid of arithmetic! Okay, as you said, you come with me." "

Guomingtang walked through the alley, turned and turned, turned and turned, walked to a hut, opened the door lock, and Qianyuan followed Wang Xiaotong in.

As soon as you enter the door, you will see a large table, with a variety of tools on the table and a lot of tables, and the appearance of the tools is strange, and you can't recognize it for a while. There was a book on the small table next to it, and Qian Yuan walked over to see that it read "The Book of Ancient Calculations".

I saw Wang Xiaotong holding a five-grid bronze ruler in his hand and comparing the scales on the wooden strips. Qianyuan didn't bother, picked up the ancient arithmetic book alone and flipped through it, opened the first page, and saw that it was written (If it is the middle of the night in November today, the day is 480 degrees 700 minutes of the 10th degree. With the chapter year as the mother, the new moon line is divided into 9,000, the new day is set to be more than 10,000, the day is 20,000, and the chapter is 700, also known as the line division. Don't take extra time today. Q: Where is the moon in the middle of the night?).

Qian Yuan hurriedly closed the book, frightened in his heart. Who wrote the book Wucao, although I didn't understand the specific meaning, but the words sun and moon, thousands of yuan can still be understood. Calculating the position of the sun and the moon, what kind of joke is Nima! Carefully looked at the bottom of the book, and there were three big characters written on it: Wang Xiaotong.

Qianyuan was in a cold sweat, and said in my heart that I was playing a big knife in front of Guan Gong. Do I want to rush if I admit defeat now?

As the saying goes, a master of arithmetic who doesn't know carpentry is not a good astronomer, and Wang Xiaotong is obviously not among them. I saw Wang Xiaotong doing carpentry work with one hand, playing with perfect fire, the small carpentry chisel flew up and down, and the wood fragments fell all over the ground in an instant. I'm afraid that this carpentry stunt is not going to be a supervisor, and he can be a master craftsman.

After a while, the small wooden barrel was ready, Wang Xiaotong filled it with water, took out a bronze square liter, and said: "I said that the water in the bucket is one hundred and ninety-five, and you say that the water is two hundred and four." This thing is exactly 200 water, if the water overflows, you are right, if there is no water overflow, you still need to review the nine chapters of arithmetic!".

After that, I saw Wang Xiaotong carrying a small bucket and slowly pouring out the water. Soon the water in the bucket was about to be poured out, and the bronze Fangsheng was already full at this time, and with the last stream of water poured in, the water tension on the surface of the bronze Fangsheng could no longer be supported, and the water flowed down the wall to the table.

Zhuang Qiangcheng doesn't deceive me! Just when Qianyuan applauded in his heart, Wang Xiaotong shouted out in a loud voice.

Wang Xiaotong screamed: "My book!".

I was so focused just now that I put the book on the edge of the bronze square sheng.

Wang Xiaotong grabbed the book on the table and shook off the water droplets, and before Wang Qianyuan opened his mouth to apologize, he bowed deeply and said: "Can you tell the child, how did you calculate the water in this bucket?"

Wang Qianyuan hurriedly dodged and clenched his fists: "Sir, don't do this, the younger generation has a method of measuring the circle is my teacher's experience, if Mr. is interested, I will talk to Mr. later." I really shouldn't have spoken wildly before, Confucius said that there must be my teacher in the threesome. Can the younger generation enter arithmetic and learn this way of arithmetic with his husband?"

Wang Xiaotong nodded: "I see, presumably your master is also an arithmetic master, although I can't teach you, but I can also guide you in arithmetic, you will come to the arithmetic class tomorrow." You don't have to worry about admission, you just need to prepare the gifts, and the rest of the old man will do it for you. "

Hearing that he would be able to go to school tomorrow, Qianyuan was overjoyed, thinking that the iron should be struck while it was hot, Qianyuan took out a charcoal pen on the wooden board and wrote out the ninety-nine multiplication table.

Wang Xiaotong didn't care about it at first, but after taking a closer look, he almost didn't pull off his beard. His fiery eyes stared at Wang Qianyuan and asked, "This method is wonderful, who is your teacher?"

Wang Qianyuan arched his hand to the east and said, "My teacher is in the sixth class of three years, and the physical education teacher is Zhuang Qiang." "
