They Have a System in Daqin

"The second method, I named it the leg lift method." Jiang Ziyi said.

"Leg-lifting method?" Chang Ping Jun looked dumbfounded.

"Yes, suppose the chicken and the rabbit both lifted one foot, then there is one hundred minus sixty left on the ground, which equals forty feet. At this time, the chicken is sitting on the ground without feet. Naturally, his feet are all rabbits."

"The rabbits at this time have their feet on the ground, so forty feet correspond to 20 rabbits."

(100-30×2)/2 is a rabbit.

30-(100-30×2)/2 is a chicken.

Although Mr. Changping could not understand the formula written by Jiang Ziyi, Mr. Changping was not a fool, and he could naturally understand Jiang Ziyi's words.

It is because I understood that I was even more surprised.

"Second, this algorithm seems to be simpler than the assumption just now, but the calculations you write seem to be exactly the same as the first one in the first method."

Mr. Changping asked if he didn't understand.

"This is the algorithm I just listed. The formula listed, the symbol '1', represents one."

Jiang Ziyi began to explain.

Why do you want to write these calculations, because after a while, you need to use the method to make the other party's eye-opener. If the other party doesn't even know this, it's nothing.

However, Jiang Ziyi had already given these figures to the study staff for use.

It is definitely more intuitive and convenient to use these figures than words.

Even people who do not know abacus can settle accounts after learning these algorithms taught by Jiang Ziyi.

After hearing Jiang Ziyi's teaching, Lord Changping suddenly felt shocked.

Although these things didn't have much effect on marching wars or the military affairs of North Korea and China, Jiang Ziyi didn't mind revealing them.

However, although these things do not have much effect on marching wars or the military and political affairs of North Korea and China, they have a very huge effect on the lives of the people.

"Seconds, seconds, this algorithm, calculation formula, and counting method were invented by Mr. Zi Yi!" Mr. Chang Ping's eyes were shining brightly, with constant emotion.

Jiang Ziyi's face is extremely thick, without the slightest hesitation, he nodded.

"Mr. Ziyi is really a god and man," Mr. Changping said with a sigh.

"Well, now that you have learned the Lord Changping, then I have to talk about the third method." Jiang Ziyi paused, then said.(Read more @ mtlarchive.com)

"What? There is a third method for this question!" Changping Jun said with a shocked look on his face.

At this time, Lord Changping had completely believed in Jiang Ziyi, and naturally he was shocked by Jiang Ziyi's third method.

For this question, Changping Jun just thought of the first method by himself, and spent three days.

And how long did it take Jiang Ziyi? Just thought of three methods? !

Could Mr. Ziyi be smarter than his niece?

Mr. Changping has some doubts about life.

Jiang Ziyi felt even more happy when he saw Changping Jun’s appearance of ‘unseen in the world’.

"Mr. Ziyi, please enlighten me."

Jiang Ziyi chuckled, "Mr. Changping, my third method is called ‘binary linear equations,’ you can listen."

Hehehehe, the system of linear equations in two unknowns is really a nostalgic thing. I think at the beginning, Jiang Ziyi was a master, if he hadn't, he wouldn't remember the paper manufacturing method.

It's just that, now Mr. Changping...

Stupid ancient people, tremble in the face of the terrible nine-year compulsory education!

After the second grade, Jiang Ziyi started his own explanation.

"Assuming that the chicken is X and the rabbit is Y, there are thirty rabbits and chickens, so X plus Y equals thirty, right."

With that said, Jiang Ziyi wrote X+Y=30

"Then, because the chicken is X, there are 2X feet, and the rabbit is Y, so the rabbit has 4Y feet, and because there are a hundred feet, 2X+4Y equals one hundred, right?"

With that said, Jiang Ziyi wrote 2X+4Y=100

Then, Jiang Ziyi started the simultaneous equations...

When Jiang Ziyi solved X=10 and Y=40, Lord Changping was already doubting his life.

who I am? where am I? What am i doing?

This situation continued until Jun Changping returned to his mansion.

His expression was desperate, his eyes were blank, as if he had been hit hard.

In his mind, there seemed to be a mess, no matter how he sorted it out, he couldn't sort it out clearly.

"Assuming that the chicken is X and the rabbit is Y, there are thirty rabbits and chickens, so X plus Y equals thirty."

"Then because the chicken is X, there are 2X feet in total, and the rabbit is Y, so the rabbit has 4Y feet, and because there are a hundred feet in total, 2X+4Y equals one hundred."

"I understand all of these. The question is how to solve the two formulas 2X+4Y=100 and X+Y=30?"

"X and Y double at the same time, why won't it affect the equations on both sides?"

"How do these two equations come together? Can you still figure out the answer?"

"My God, what is going on with this two-dimensional linear equation system?"

Jun Changping seemed to feel the fear from the nine-year compulsory education and felt his scalp tingling.

"Xiong Qi, why do you look melancholy?" At this moment, a big man appeared in front of Jun Changping.

"Tian Guang, it turned out to be you." The other party suddenly spoke, making Jun Changping startled. After seeing Tian Guang, Jun Changping breathed a sigh of relief.

Tian Guang, the contemporary chivalrous leader of the farm, is in charge of the farm.

"Xiong Qi, you should have met Jiang Ziyi just now, what do you think of others?" Tian Guang asked after seeing Lord Chang Ping and returning to his senses.

Hearing Tian Guang's culture, Mr. Changping also calmed down.

"The other party is very smart, very smart, very smart." Changping Jun said.

"What? Is there nothing else except this?" Tian Guang felt a little confused.

"No, let's not talk about anything else, but cleverness is his characteristic."

"Don't you often compare Tian Yan to a peasant female Guan Zhong? I feel that even Guan Zhong is not necessarily comparable to him!"

"what?!!"
