"Honorable Governor" Tang Ruowang with a strange accent of Chinese, so that everyone in the room felt funny, Ulding knew that there were dialects in the Ming Dynasty, he asked a picture on the side, "Where is this dialect" Praise painting covered his mouth and smiled, "Hehe, this is Xiyi's barbarian language." Several people on the side laughed, they all thought that Tang Ruowang couldn't understand the meaning of their words, so they laughed at him so fiercely.

"I am a missionary from Europa, not a barbarian, please respect a civilization equal to you, I speak English, not barbarians, I am not Germanic!" Tuo Ruowang said so seriously, everyone laughed, as if they had stopped laughing funny, and the princess snorted, "Xiyi, this palace has heard of it, it is not civilized, rude, righteous and shameful, chasing fame and fortune, and a barbarian land!" Her voice was cold, and everyone nodded in agreement.

All the missionaries blushed and said, "You can't look down on other peoples and countries just because you have powerful firearms, although Europa does not have powerful rockets, but we have far superior knowledge of mathematics, and even physics and geography. ”

He said that Magellan's circumnavigation of the world had already taught Europeans that the earth was round, not square! He was going to start from this place, and get the other party to agree to his missionary affairs in Hebei, and first show his profound knowledge, this group of Orientals is very ignorant, they still think that the earth is square.

"Are you going to say that the earth is a sphere, or are we in the universe?" Xiao Chuan smiled, Tang Ruowang in front of him had a strange face, the other party actually knew about these geographical discoveries, so start with mathematics "The Ming Dynasty abolished the imperial examination arithmetic, we in Europa have more advanced mathematics, which can help you improve your mathematical ability"

"Math!" Hearing this name, some people didn't react, and the princess said, "Arithmetic, these blonde barbarians are really good at arithmetic, and they can really give us some help" Some people nodded on the side, and some people felt disapproving, and the Ming Dynasty began to abolish the arithmetic in the imperial examination.

Tang Ruowang's face was full of pride, Xiao Chuan's face changed, and he said, "In this case, Europa's mathematics is very good, so I will test you to see if you can calculate" The university in the previous life, the points and points are these things, which is the Tang Ruowang in front of the test.

"Oh!" Tang Ruowang had a kind of expectation on his face, he was good at mathematics, he was really not afraid of the problems of the Easterners, the mathematics of the East was more imaginative than that of the West, but he didn't believe that the martial artist in front of him would have more mathematical ability than himself, not to mention that there was a team behind him, he was just one person.

All the generals in the house had strange faces, and the prince asked a question, and everyone gathered around, and the princess said worriedly, "Don't, this group of Xiyi is really proficient in mathematics!" He said worriedly, Da Ming is a little wasted on mathematics, and Kaiyuan is not very good.

"It's good to draw the problem, don't talk" Xiaochuan said, is to let the princess pick up the pen and ink on the table and draw it, it is an integral problem, first a curve equation, for mathematics, because of the support of the philosophy of yin and yang, the East discovered positive and negative numbers a thousand years earlier than the West, as well as a series of mathematical achievements, but there was a government ban on the study of mathematics, just like the Eastern Jin Dynasty, prohibiting people who studied mathematics from contacting the people in power at that time.

"Curves? Is this to solve the equation or to find the derivative" Tang Ruowang didn't understand, looking at this curve, the princess's slender jade hand drew a coordinate system on the paper, and then drew a beautiful curve, listening to Xiao Chuan's words, writing his decomposition, his face was full of confidence, and he wanted to use Europa's mathematics to give this group of Orientals a little color. There are also praise paintings on the side that are good at arithmetic, and I look at them carefully. "Kaiyuan technique, this problem can be solved by Kaiyuan technique"

Xiao Chuan drew two lines on it, and said, "Ask for the area here" Tang Ruowang's face immediately changed, and said, "Area? Is this question about finding an area, so is it geometry, or is it a curve? He glanced at his companion behind him, and his face immediately showed a difference, he didn't imagine that the other party actually had such a problem?

Curve? Or geometry? He began to think about the relationship between this curve and this strange closed interval, and the praise paintings on the side also began to be counted, and the generals were surprised, they couldn't understand the topic, the princess was condensed, she could also write arithmetic, but this topic was like an antelope hanging horns, so that people could not find it. "Childe, you know the answer to this question" he asked, Ogawa practiced calligraphy and writing extremely ugly, she didn't think that the other party would know such an esoteric math problem.

Tang Ruowang and the others were all bitter, brushed and brushed a large number of formulas on this paper, wrote for half an hour, the paper in the room had been used up by them, he raised his head, stared at Xiaochuan with bloodshot eyes, and said, "Childe, do you really have an answer to this question?" The missionaries in the back also raised their heads, and the faces of the people were strange, is there really an answer to this kind of problem?

Xiao Chuan explained the fixed integral, if you write the answer on the paper, the handwriting of the crab crawling will definitely attract the ridicule of a lot of people, there is no way, so I have to explain it like this.

John Tang and the others were fascinated by what they heard, and they realized that there was still this kind of practice that could combine geometry and equations, and they praised their faces? With eccentricity, I began to re-accept this new knowledge.

"Governor, where did all your mathematical knowledge come from" John Tang raised his head, his face was strange, this kind of mathematical problem-solving ability has surpassed Europa, and he has never heard of something called integral in the East.

"This" Xiao Chuan smiled, did not speak, and said to the princess on the side, "Naturally, it is the Governor, who studied it himself, and he has a deep attainment in arithmetic."

John Tang was shocked, and it was no longer a genius to describe such a complex thing that he had personally researched, but it also made him very embarrassed, how could he obtain the status of a missionary in the East. "This!" The missionaries were embarrassed that not only did they not get missionary status, but they also lost in mathematics.

"Report, Shaanxi is in an emergency" A man in black suddenly walked over on the side.

************

Soon, a math problem spread rapidly, and the prince knocked on his desk angrily, his face was full of anger, and said, "This group of Xiyi really doesn't know loyalty, how many benefits this palace has given them, I don't know how much thanks, just leave, hum!" He said angrily, and everyone around him was so angry.

"So, I have long felt that this group of Xiyi is not respectful to their ancestors and is not worth believing" Tang Yan said on the side, "Sure enough, I ran to Hebei" He snorted and said.

The prince is extremely disappointed, that is, lost, the loss is not that the other party is gone, but arithmetic, Qin Xiaochuan's points came out, and he pressed him in arithmetic, and said, "Recruit people, calculate this problem!" ”

Everyone was surprised, what's wrong with Your Highness, why can't you suddenly get along with arithmetic today, Tang Yan said, "Your Highness, this arithmetic is useless!" "Everyone nodded/

"Humph! I don't believe it, in the south of the Yangtze River, no one can solve his problem by someone who is a person of arithmetic! ”
