Daqin: Zulong Asked Me to Be the Prince

On the outskirts of Xianyang, the two of them were walking on two cavalry, followed by a few soldiers who were escorting them.

"Are you really Zhang Cang?"

Qin Feng looked at the fat man beside him who was eating candy all the time and couldn't help asking.

Even though he has an average history, the name Zhang Cang has been heard before!

"Nine Chapters of Arithmetic" was compiled by this kid! In the late Qin and early Han Dynasties, Zhang Cang could be regarded as the most powerful mathematician, scientist, and economist!

Not to mention, he is in charge of Qin State's library, and he is also the librarian of Daqin! It can be said that he is full of knowledge, whether it is foreign language or mathematics, physics and chemistry, it is top level!

It can be said that in the whole of Daqin and even the world, only Zhang Cang can discuss mathematical problems and scientific ideas with Qin Feng.

Only his mind can keep up!

In Qin Feng's previous plan, he planned to find Zhang Cang, to amaze him with his middle school level "zero-one-seven" learning foundation, and then let Zhang Cang push ancient mathematics to a new level!

After all, mathematics is the mother of all sciences.

But what Qin Feng didn't expect was that Zhang Cang was such a fat man with a big belly and a love for sweets!

To be honest... it's a little different than I imagined.

"I'm Zhang Cang! Is this still fake?"

Zhang Cang, carrying a small luggage, said suspiciously,

"Do you want me to show you my testimonial?"

Qin Feng waved his hands again and again.

"No need, no need, I'm just a little surprised that Zhang Cang looks like this. 35

he quipped,

"You are nutritious!

Zhang Cang smiled and said:

"Being human! Just enjoy! 55

"Of course, I really can't compare to those of my senior brothers! Among my master's disciples, I am the most incompetent!

"But he loves me the most."

Speaking of which, Fatty seemed a little proud.

His master is Xunzi!

And his senior brother is Han Feizi and Li Si!

Indeed, just pick one out, and they are all amazing characters of the era!

"You are not bad, your achievements in mathematics are unparalleled!"

Qin Feng praised,

"Actually, I am also very interested in mathematics! 99

Hearing this, Zhang Cang's eyes lit up.

"Oh? Brother Qin Feng is also interested in mathematics?" He immediately became interested and said. "Do you know that there are several algorithms for the evil field (right-angled trapezoid)? I tell you, there are three. The first one, and two evils, multiply the positive from..."

He spoke a lot, and spat out various professional terms.

After finishing speaking, he still looked at Qin Feng expectantly, expecting Qin Feng to understand.

Qin Feng said: "...I don't understand! What you said is too complicated!

Zhang Cang sighed.

Sure enough, no one can understand his favorite math technique!

"Add the lengths of the upper and lower bases, multiply their heights, and then halve them! Don't you get it?"

Qin Feng wondered,

"Why are you making so much trouble?

Zhang Cang: "???"

"The length of the upper base plus the lower base... times the height..."

"Wow! That's right! It can still be counted like this! Why?!

"Oh right...this is a simplification of the complex, the same principle as I said, but simplified!

"Take it down, take it down!"

66.99

As soon as Zhang Cang patted his head, his whole body became excited. He even took out a bamboo slice on the horse's back and started taking notes!

This fat man may be able to drive very steadily because of his large tonnage. No matter how strong the horse is, he can only carry it hard, and he does not dare to splash.

He just sat so steadily, remembering.

Qin Feng was very satisfied with his appearance.

This is the learning attitude that a great mathematician should have!

Apart from the fact that Zhang Cang's appearance doesn't quite match what he imagined, the others are quite in line with expectations!

After a while.

"Remember! In the future, the evil field will be counted like this!"

Zhang Cang gathered up the bamboo pieces with satisfaction, looked at Qin Feng and praised,

"Brother Qin Feng, you are really a genius! You are able to simplify the complex, and you can think of an algorithm that I can't think of! 99

"Zhang Cang finally met someone who can talk about arithmetic! Great luck! It's right to come out this time!"

He was all excited, looking at Qin Feng as if he were looking at a beautiful woman!

The so-called bosom friend is hard to find! It is very difficult to find someone who knows arithmetic in the Qin Dynasty, let alone discussing arithmetic!

He tried to talk to people before, but people fell asleep after listening to it for a while. After a few times, Zhang Cang stopped communicating mathematics with others.

But Qin Feng's opinion is even higher than his! How can this make him not excited?!

66' Brother Qin Feng! Do you know how to convert between corn and rice?"

"Brother Qin Feng! Do you know how to withdraw if the surplus is insufficient?"

"Brother Qin Feng..."

He eloquently chanted terms that Qin Feng couldn't understand, buzzing like a fly.

Qin Feng was annoyed and interrupted:

"Brother Zhang Cang! Stop talking about it!"

"I have a question that has been bothering me for a long time, and I have not been able to solve it. Can you help me solve it?"

Zhang Cang's eyes brightened, and he continued: "Okay! But it's okay to talk!

He likes this kind of discussion between you and me the most! It's boring to talk about it alone!

"Please listen to the question!"

Qin Feng said with a smile,

"Suppose there are chickens and rabbits in one cage! Together they have 30 heads and 88 feet—"

"Excuse me, how many rabbits and chickens are there in the cage?"

In order to be quiet on the way, Qin Feng went directly to the chicken and rabbit cage!

This may not be a difficult problem for elementary school students in later generations, and a very simple one-dimensional linear equation can be solved.

But in this day and age, it takes a little ingenuity to solve this problem.

With Zhang Cang's wisdom, he can naturally solve it, but it doesn't matter, chickens and rabbits in the same cage are just appetizers, and there are still "the problem of releasing water and storing water" and "the problem of A and B chasing and meeting" waiting for him!

Enough for Zhang Cang to solve 2.6 for a while!

By the way, he can also teach him the method of planning and the equation, and let him study it!

In this way, he can be regarded as promoting the development of mathematics in the Qin Dynasty, right?

"30 heads, 88 feet..."

Sure enough, Zhang Cang fell into contemplation in the face of this question, he no longer chirped, his brain was thinking with all his strength!

He needs sugar!

Kaza Kaza! A piece of brown sugar was chewed by him and put in his mouth!

The sweet taste made him think of the possibility of a crack!

"I get it!

He shouted, took out the bamboo slices and started counting.

And Qin Feng was humming a little tune.

He has a revolver around his waist and a majestic horse under his crotch!

Walking in the countryside of Longxi, he is like a cowboy in the west, wanton and unrestrained!!.
