"Your Majesty is here to see me, but is there something wrong?" Xu Guangqi knew that the emperor would not come here for nothing, and would definitely come with something. He tried to ask.

"Haha, Master Xu is good as expected. I have something to do. I am going to talk to Master Xu." Yang Jingwei really has something to talk to Xu Guangqi.

"Your Majesty, what's the matter? But what's going on with drought and disaster resistance, sweet potatoes? In this way, the old minister has already made arrangements and is about to report to Your Majesty." Xu Guangqi thought the emperor wanted to discuss the sweet potatoes with him.

"Haha, since I have handed this sweet potato matter to Master Xu, I naturally trust Master Xu. This requires people, things, and money. Master Xu just talks, and I will definitely support Master Xu with all my strength. I come here today, first of all, I am not worried about Master Xu's body, so I came to see it. Secondly, I have to discuss some math things with Master Xu." Although Yang Jing was very concerned about the promotion of this sweet potato, he also knew that sweet potatoes did not grow from the ground in a day or two. Since it was explained to the people below, it was enough to keep attention and support. There was no need to interfere too much, and he did not have so much energy to interfere.

"Then I thank Your Majesty. I do need some money and mobilize some people. Since Your Majesty let go, the old minister is arrogant. Haha, I wonder what mathematical things you have to discuss with me today?" Xu Guangqi's sweet potato promotion plan had been agreed before, but this specific implementation requires money and manpower. Therefore, this requires the support of the emperor and the strength of the emperor's support is directly related to the effect of the sweet potato promotion. Today I got the emperor's guarantee again, and I put down the burden in my heart and began to discuss the mathematical things with the emperor.

"Big companion, bring my paper bag."

Wang Chengen quickly took a paper bag and handed it to the emperor.

Yang Jie took the paper bag, took out a few pieces of paper from it, handed it to Xu Guangqi, and said, "Master Xu, look at these symbols. I think that the mathematical operation is too complicated to write in words, which is not conducive to rapid writing, not conducive to understanding, and not conducive to large-scale calculations. Therefore, I used some simple symbols that can be completed in one stroke to replace these words. In this way, I think it can speed up the mathematical operation and facilitate writing. I think it is useful, so I will show it to Master Xu. I want to hear Master Xu's opinions."

Xu Guangqi took the pages and looked carefully. From the beginning, frowning to the confusion later, and then, there was a hint of smile, and then, he was already focused.

Yang Jing had 100% confidence in his "things" and could impress this mathematical pioneer. What Yang Jing gave to Xu Guangqi was actually very simple, which was the symbolization of operations in later generations, using Arabic numerals and "+-x/" operators, plus symbols such as a, b, c, and d instead of text.

This not only uses simple symbols to replace the complicated "text numbers" written, but also uses symbols to perform mathematical operations. This will make ancient mathematics sublimate from focusing on practicality to focusing on theory, opening a skylight for "science" in the late Ming Dynasty.

Yang Jingwei has also read the "Geometric Original" translated by Xu Guangqi. The graphics and angles in it are also used in Chinese characters such as angle A, angle B, and angle C. It is not a Western abbreviation such as a, b, and c. It is more troublesome when it is used. Therefore, Yang Jingwei intends to promote the symbolization of this number and the symbolization of operations, accelerate the development trajectory of this "mathematical science" and improve the development speed of mathematics.

After watching for a while, Xu Guangqi said, "Your Majesty is a genius. Your Majesty is not as good as you can. In this way, mathematics will undergo earth-shaking changes. From then on, it can be considered as the universe, the small dust, the movement of stars, and the farming calendar. I didn't expect that Your Majesty can have such an opinion. The old minister has nothing to teach Your Majesty. The ancient saying says, "The master is the teacher." The ancients really did not deceive me... With Your Majesty's symbolic calculation technique, the old minister should take Your Majesty as his teacher!"

Xu Guangqi was serious about taking the emperor as his teacher. This made Yang Jing extremely embarrassed. He just "stealed" the mathematical achievements that would take one or two hundred years to "steal" them. He was not considered his own achievements. He was no longer as good as some "bricks" who just put gold on his face. He didn't have that kind of "ability" yet. He hurriedly said, "Master Xu must not do this. I was interested in mathematics because I read Master Xu's "The Origin of Geometry" and studied it. I also had the idea of ​​promoting the technique of symbolic operations. Besides, the symbols in the technique of symbolic operations, and the symbols representing numbers are not my first creation. I am not.

It is just to transplant the wisdom of others. I asked Tang Johnson. He told me that the original book of "The Original Geometry" uses symbols to represent angles, and Master Xu's book seems to use this text to record and translate. In this way, the records are complicated and difficult to understand. Moreover, it is impossible to perform effective calculations. I think that since using symbols is conducive to writing and understanding, and also to calculations, I can simply replace them with symbols. Therefore, I am not a first-in-one, just summarizing and promoting, not a genius that Master Xu said. Besides, if I am addicted to this, the ministers will inevitably be too long-winded, and I will blame Master Xu for being a poor teacher."

Yang Jing didn't want to get the title of "Mathematics Brick Emperor". In this way, wouldn't it be too "face", or, in the future, there will be an Internet and a starting point. When others write about time traveling through their own period and checking information, they will definitely reveal that they are time travelers! Isn't this too obvious? At that time, the people from the Time and Space Administration will come to arrest them, but what should I do? I quickly refuse and throw these operating symbols and Arabic numerals to outsiders. This must not be required.

"Your Majesty is right. Thank you for your reminder. I am confused and should not let Your Majesty be addicted to this path." Xu Guangqi saw the emperor's constant refusal, and it made sense. The emperor is the emperor and should not specialize in this kind of "left-minded way". Otherwise, if the court officials know it, they will inevitably give advice again, so they will no longer say anything about taking the emperor as their teacher.

Yang Jing wiped his sweat in his heart, which was really dangerous. In the future, he would have fewer titles and inventions, and found them all on his head. In this way, when others checked the information in the future, I damn, in modern times, more than 90% of the world's important inventions were invented by the great "Sheng Emperor". This guy is clearly a time traveler. Otherwise, how could he have invented so many things that have affected the world in just a few years?

Xu Guangqi's eyes were a little vague, and he wiped his beard and said, "Your Majesty wants to promote this symbolic operation technique. According to my opinion, you will be able to rewrite the history of this mathematics! Alas... It's a pity that Your Majesty is the emperor. Otherwise, your achievements in this mathematics will be limitless! What a pity, what a pity..." Xu Guangqi felt sorry for him again. Such a smart boy is a pity that he is an emperor. Otherwise, if you are dedicated to this mathematics, you will carry forward this mathematics and leave it in history. It will be remembered by future generations.

"Oh, Master Xu, I am going to promote this symbolic calculation technique immediately. I think that the mathematics of our dynasty will surely take off. I always feel that this mathematics will be the key to the world's truth! So, time is too late, and I am eager to find Master Sun?" Yang Jing's research on this mathematics is a complete novice. Of course, thanks to these nine years of compulsory education, Yang Jing's math scores are not bad. If you want to talk about how to calculate, Yang Jing must know something, but if you want to study mathematics and study the improvements of ancient mathematics, you really don't know why. Typical ones only know the truth, but don't know why. This depends entirely on Xu Guangqi.

Only by promoting the symbolization of mathematics can we completely end the ancient Chinese perspective of focusing on practicality and not theoretical system research. Let this key to open the door to science appear on the land of the Ming Dynasty as soon as possible.

"A key? Your Majesty's metaphor is really appropriate!... Your Majesty, if you promote this technique, it will definitely be the greatest success in the history of mathematics in our dynasty! Thinking about the land of China, all dynasties have only paid attention to this practical application, not the reason. It is a mistake to use this text as a expression for counting, writing, and calculation. I originally wanted to advise Your Majesty and study the method of calculating this symbol instead of text for calculation. Unfortunately, various reasons have not been realized, so that the old minister's translation has to use text as a expression.

This is really my regret, but I didn't expect that Your Majesty is so smart. Just after reading it, you will understand the truth. It is really a blessing for our dynasty! I have said earlier this mathematics, 'Those who can master this book cannot be perfect; those who like to learn this book cannot learn anything.' I also think that this mathematics, as Your Majesty said, is the key to opening the door of truth in the future! I think that this mathematics, 'in a hundred years, no one will not learn it'. Your Majesty's move is a blessing for generations! It is a blessing for China."

Xu Guangqi sighed at China's mathematical mistakes and predicted the historical role of mathematics in the future. This vision made Yang Jing admire him. This is the giant of history, the great man who can clear away the fog of history and see the future. He is not his time traveler who relies on future knowledge to make a living.

"I have a deep sense of Master Xu's words. I also feel that this mathematics will be the key to unlocking all the secrets in the universe in the future. Therefore, when I think of this, I feel deeply pressured and responsible. I urgently hope to introduce it as soon as possible, promote the symbolization and calculation of this mathematics, so that our dynasty can open up a new situation. If we can really unlock the secrets in the universe in the future, I will surely not forget the decisions made by you, my king and my minister today!"
