"Seeing your two highnesses, I didn't expect to meet your two highnesses again."
Gao Zhang entered the palace slowly. Before he could go to the imperial study, he happened to meet Zhao Huan, the eldest son of the emperor, and Zhao Fujin, the beloved daughter of his master, who were walking together.
Gao Zhang, who had met many people in and out of the palace these days, bowed respectfully to the two of them very calmly.
Nowadays, the eldest son of the emperor, Zhao Huan, is already eleven years old. However, he is not as tall as Zhao Fujin, who is one and a half years younger than Zhao. It is normal for girls to grow fast.
Although Zhao Fujin's name is very blessed, he is now slim and charming.
When he saw Gao Zhang, he showed a sweet smile and saluted Gao Zhang.
"Brother Xiao Gao, my brother and I are here today because he encountered a problem, so I came here to ask Brother Xiao Gao for advice."
Gao Zhang suddenly nodded and his eyes fell on Zhao Huan, but he always felt that Zhao Huan was a little sick and obviously lacked energy.
Then Zhao Fujin on the side couldn't help but stretched out his finger and poked his eldest brother Zhao Huan.
Judging from the sheen of sweat on the tip of her handsome nose and the slight blush on her lovely cheeks, she is indeed a promising beauty.
A pair of moist eyes that always seem to have feelings that they want to express.
Zhao Huan saluted Gao Zhang, glanced at the girl with whom he had a very good relationship, and then spoke.
"Yes, yes, brother Guizhang, I have been reading "Sun Tzu Sutra" for the past two days, and I didn't expect to encounter such a problem."
"Brother, I don't know how to solve it, so I just came here to try my luck. I never thought that I would actually meet Brother Guizhang."
"What is the problem that it is rare for you, Your Highness, to live here?"
"This is a question about a chicken and a rabbit in a cage. The question is: 'There are chickens and rabbits in the same cage today. There are thirty-five heads on top and ninety-four legs on the bottom. What are the geometry of each chicken and rabbit?'..."
After hearing this question, as an art student with a background in science and a strong ability in mathematics, physics and chemistry, Gao Zhang had the answer flashing in his mind almost without thinking.
However, pretending requires a process and cannot be accomplished overnight. That way there is neither pleasure nor the sense of accomplishment brought by the emotional changes of the audience around you.
So Gao Zhang smiled and nodded at Zhao Huan in front of him.
"This question is indeed an exquisite question in Sun Tzu's Suan Jing. I don't know where His Highness is stumped. Maybe someone can help His Highness clear up his doubts."
"Brother, brother Xiao Gao, this is not the place to talk. How about we move to the pavilion?"
#####
The pavilion had obviously been decorated. Gao Zhang sat down in front of the writing desk without any hesitation, picked up a pen, and then wrote a formula directly.
Looking at the strange characters on it, both Zhao Huan and Zhao Fujin were confused.
"This is called a linear equation of two variables, or it can also be called a linear equation of two variables..."
Gao Zhang talked for a long time. Depending on the conditions of the question, the eigenvalues a and b can be integers (the number of chicken or rabbit feet) or non-integers (the unit price of a certain commodity).
The standard solution to binary equations in junior high school is substitution or addition and subtraction (also called Gaussian elimination).
Of course, Cramer's rule can also be used to perform "matrix division".
Seeing the increasingly confused eyes and expressions of the brother and sister, Gao Zhang wiped his face silently. It seemed that the brother and sister were just curious and did not study mathematical problems.
After clearing his throat, he directly pulled aside the previous paper filled with formulas and continued his analysis.
"Actually, if we want to understand the result of this question more simply, there are three methods."
"There are three more?!" The brother and sister were completely shocked beyond words.
After all, he, Zhao Huan, had asked his teacher for advice on this issue and knew how to use arithmetic chips to calculate.
But just now, this brother Guizhang used the calculation method. He didn't even use the calculation chips and the abacus placed next to him. He just took a pen and drew on the paper and got the result.
Now he told himself that he still had a way to solve this problem.
"Brother Xiao Gao, what are the three other solutions? Can you tell me so that our brothers and sisters can also open their eyes."
At this moment, Zhao Fujin had bent his knees and sat next to Gao Zhang.
Those watery bright eyes were full of admiration and surprise.
"Of course there is no problem. These three solutions only involve the representation of the problem, so they can be collectively called representational solutions..."
Gao Zhang put pen to paper, and his hand was no less beautiful than Master Zhao Ji's thin golden body.
"Guess method, hypothetical method, and leg raising method?"
"Yes, I use the stupidest way to guess, which is to make a table."
As a top student in science, Gao Zhang was able to use simple and easy-to-understand language to help these two boys and girls, who are just in elementary school, understand how to use these three representational solutions to solve the problems in "Sun Zi Suan Jing".
The point is, it can make them all understand the truth, and the brother and sister nod frequently with a look of surprise on their faces.
#####
"Sure enough, I knew that Brother Xiao Gao would have a solution."
When Gao Zhang put down his brush, Zhao Fujin on the side raised his pretty face with joyful brows. In the sunlight, you could still faintly see the faint down on his face.
It is increasingly revealing the cuteness and childishness of a green and girlish person.
Facing this pair of master and children with whom he had a good relationship, Gao Zhang naturally would not be arrogant, but just calmly humble.
After chatting with them for a while, they left.
"Brother Xiao Gao, let me give it to you."
When Gao Zhang turned around, he saw Zhao Huan staying in the pavilion, while Zhao Fujin took steps to catch up with him.
Gao Zhang saluted Zhao Huan, and then walked forward side by side with Zhao Fujin.
"I saw the poem that you wrote the other day, Brother Xiao Gao. It was so well written. Brother Xiao Gao, what were you thinking when you wrote the poem "Bodhisattva Man"?"
Listening to Zhao Fujin's clear and sweet voice, Gao Zhang laughed, deliberately looked around, and lowered his voice.
"I was just thinking about what kind of content I could write to satisfy your father."
"If my master doesn't like it, no matter how good the writing is, what can I do?"
Zhao Fujin smiled sweetly, nodded obediently and agreed.
"Yeah, yeah, that makes sense, if my little sister would think so too."
Looking at Brother Guizhang, whose stature is becoming more and more like a tree, and the girl who is tall and graceful, but it is obvious that his heart is already budding.
Standing in the pavilion, Zhao Huan could do nothing but shake his head and sigh.
Who made my father's beloved disciple, Brother Guizhang, not only talented and talented, but also so eye-catching and dazzling?
All the women in Bianliang, Tokyo, regarded the unmarried Number One Scholar as their favorite.
Therefore, it is normal for his sister to admire him.
