Time flies, and there is no return.

At this time, the order issued by Yingzheng to seek talents also responded, and talents who wanted to get ahead from the six countries of Shandong continued to enter Daqin Xianyang.

Under Tie Ying's arrangement, all of them lived in the official post in Xianyang City, and this time, in order to discuss with Yingzheng for Yinggao, Zhang Cang was transferred back.

Because Zhang Cang is a mathematical genius!

In history, Zhang Cang once revised the "Nine Chapters of Arithmetic" and formulated the calendar.

Such a talent must be allowed to shine in his own position, the future Daqin does not lack the talent of the prime minister, but lacks the genius of mathematics.

That's why he grinded to let Yingzheng transfer Zhang Cang back.

……

"Childe, today is a meeting between the scholar and the childe who is proficient in the arithmetic of the nine chapters and the arithmetic that expounds the Gaitian theory and the four-point calendar."

Tie Ying's eyes were like torches, looking at the young man in front of him, he naturally knew how much Yinggao had paid for this matter, and how much he attached importance to this matter.

That's why he reminded him.

"Prepare the car, go to the Math Palace!"

After a long time, Yinggao commanded Tie Ying, and the whole person walked out of the study, he had been a master in Sanchuan County once, and now he was going to return to his old business.

It's just that compared to being in Sanchuan County, Yinggao obviously has a little more excitement in his heart this time, because he knows what he is doing this time.

Maybe this is the beginning of an era!

……

"Rumble ......"

The car rumbled, drove through the quiet street, and finally entered the Daqin Central University, and since part of the building had been completed, this meeting was arranged in the School of Mathematics.

Yinggao is looking forward to this meeting, after all, the people he wants to meet are basically some of the best geniuses of this era.

He knew that in this era, there were already seven strategies, nine chapters of arithmetic, and a monograph called arithmetic by later generations.

In particular, the Nine Chapters of Arithmetic, "Nine Chapters of Arithmetic" also has its own unique achievements in mathematics, not only the first mention of fractions, but also the first record of surplus and shortage.

In the chapter "Equations", negative numbers and their addition and subtraction operations were expounded for the first time in the history of world mathematics.

Ying Gao remembers very well that in the nine chapters of arithmetic, the first chapter, "Fang Tian": mainly describes the calculation method of the area of plane geometric figures.

It includes eight methods for calculating the area of the figure: rectangle, isosceles triangle, right-angled trapezoid, isosceles trapezoid, circle, fan, bow, and circle.

In addition, the four rules of operation of fractions and the methods of finding the greatest common divisor of the numerator and denominator are systematically described.

Chapter 2 "Corn": The Proportional Conversion of Cereals; Proposed a proportional algorithm, known as the present technique; The decay chapter proposes the law of proportional distribution, which is called decay;

Chapter 3 "Decay": The Problem of Proportional Distribution. Chapter 4 "Shaoguang": the area and volume are known, and the length of one side and the length of the diameter are reversed; The method of opening the square and opening the square is introduced.

Chapter 5 "Commercial Merit": Earth and Stone Engineering, Volume Calculation; In addition to various three-dimensional volume formulas, there are also engineering allocation methods;

Chapter 6 "Equal Loss": Reasonable Allocation of Taxes; Solve the problem of reasonable burden of enslavement with decay method. Today's techniques, decay techniques, and their application methods constitute a complete set of proportional theories including today's positive and negative proportions, proportional distribution, complex proportions, and chain proportions.

Chapter 7 "Surplus and Deficiency": that is, the problem of double management; Three types of profit and loss problems are proposed, namely, surplus deficiency, surplus and shortfall, and two surplus and two shortage, as well as some solutions to some general problems that can be turned into surplus and deficit problems by two assumptions.

Chapter 8 "Equations": Problems of a system of equations; The method of separating coefficients was used to represent a system of linear equations, which was equivalent to the current matrix.

The direct division method used to solve systems of linear equations is consistent with the elementary transformation of matrices. This is the world's first complete solution to a system of linear equations.

This chapter also introduces and uses negative numbers, and proposes the method of plus and minus - the addition and subtraction of positive and negative numbers, which is exactly the same as the law of numbers in later generations; When solving a system of linear equations, the multiplication and division of positive and negative numbers is actually performed.

This is a major achievement in the history of world mathematics, breaking through the range of positive numbers and expanding the number system for the first time.

Chapter 9 "Pythagorean": Various problems solved using the Pythagorean theorem. The general solution formula for the Pythagorean number problem is proposed: if a, b, and c are the Pythagorean hook, fend, and chord, respectively, then, mn.

……

In later generations, Yinggao once studied the nine chapters of arithmetic, and at that time, he was shocked by the wisdom of the ancients, and after coming to this era, he sent people to look for it.

Naturally, he has an excellent understanding of the arithmetic of the nine chapters, and it is precisely based on this that he feels that there is a certain foundation for the establishment of the School of Mathematics.

Among the eight colleges, in fact, the most foundational is the School of Chemistry, the School of Physics is filled with Mohist scientific concepts, and only the School of Chemistry is basically poor and white.

But in this era, there has never been a shortage of smart people, sometimes just because of temporary limitations, and with the guidance of Yinggao, it will inevitably develop rapidly.

The thought flickered in his heart, Yinggao had great expectations for the future of the Great Qin Central University, and he believed that the fruits planted today would inevitably make the future of the Great Qin Empire even better.

……

"Childe, we're here!"

Getting down from the car, Yinggao said to Tie Ying: "The car is parked here, you go in with my son!" ”

"No."

This time, although the order is for talented people in the world, Yinggao knows in his heart that there must be spies from the six countries.

Even though it is a double screening of Bai Ze and Black Ice Terrace, there are still some fish that slip through the net, so it is necessary to pay attention to safety.

……

Walking into the school, there were more than 20 people sitting in it, there were people of all ages, Yinggao chuckled lightly, and stood on the podium: "Everyone, this son is here to introduce himself, Yinggao, the third son of Daqin." ”

"He is also the initiator and builder of Daqin Central University, and where you are located is the School of Mathematics, and the arithmetic you are proficient in, and the nine chapters of arithmetic are one of them."

"To enter Daqin Central University, you need to take a unified assessment, and then decide how much you will earn during your teaching at Daqin Central University!"

"In Daqin, those who are able to work harder, and the same will be more ......"

……

For these people, Yinggao is a treasure, but he knows how difficult it is to cultivate a talent who is proficient in nine chapters of arithmetic.

And he didn't have so much time to cultivate, after all, the war of Great Qin to destroy Han had only been more than two years.

Although he is the sacrificial wine of the Central University of Great Qin, however, in the Great Qin, the country is established by force, and military merit is the foundation of Yinggao's foothold in Great Qin.

He's not going to put the cart before the horse!
