Datang: I am the founding general in the beginning

Zhao Ziyun looked at their panting appearance and was very satisfied.

"Ladies and gentlemen, how do you feel about this method of this king?"

"Lord Wang, I feel refreshed and energetic, I don't know how much more enjoyable than teaching on weekdays?"

"Yes, Lord, I feel very comfortable, my blood is surging, and my head has become much clearer. Some

masters who were closer to Zhao Ziyun generously expressed their feelings.

The eldest grandson next to him, Wuji, smiled and touched his short beard.

"Very well, as long as you think it is good for you, then you can do it every morning in the future, and it will be good for your body.

"We will exercise every day after tomorrow, please rest assured."

Although Zhao Ziyun said this, he felt in his heart that it was really naïve to let a group of old masters do such campus-based gymnastics.

I guess they're just talking.

But, anyway, he's having fun.

"You have a break, and we will begin today's assessment.

After Zhao Ziyun finished speaking, those masters went out to rest on their own, and he himself reminisced about the strange scene just now.

After a cup of tea, the exam began.

After the eldest grandson Wuji made arrangements, Zhao Ziyun read the question to them.

Of course, it is also carried out in batches, otherwise it will be difficult to assess.

"Now there are three sheaves of fine grain, two sheaves of medium grain, and one sheaf of inferior grain, for forty sheaves of grain. "

If you have two sheaves of the best grain, three sheaves of medium grain, and one sheaf of the lower grain, you will get it together." Thirty-four buckets. "

If you have one sheaf of the finest grain, two sheaves of medium grain, and three sheaves of the inferior grain, you will have twenty-four sheaves of grain.

"Ask, how many buckets of upper, middle and lower third-class millet are in each bundle?" This

is a ternary equation, and it is also from the title in "Nine Chapters of Arithmetic", but Zhao Ziyun changed the numbers in it, and the

original problem has a numerator and denominator, which is more complicated, and Zhao Ziyun is convenient for them to calculate, so it is simple.

However, as soon as the question came out, everyone's faces were full of black lines, and they fell into infinite calculations.

Today's question is a skyrocketing difficulty for them.

Zhao Ziyun deliberately observed Kong Yingda, and even he was sweating profusely.

It took half an hour for this question to come over with his own test papers, and everyone else was still calculating.

"Lord Wang, this is my test paper, please take a look. Obviously

, Kong Yingda is the fastest calculator, Zhao Ziyun took his answer, only to see that it was written: ten buckets of the upper grade, four buckets of the medium grade, and two buckets of the inferior grade.

Zhao Ziyun nodded with satisfaction.

"Dr. Kong is really erudite, and you can figure it out with such a question. "

Haha, the prince has won the award, this is the equation in the nine chapters, and it is the most difficult topic in the nine chapters, but I didn't expect the prince to also study arithmetic, and the officials admire it." Kong

Yingda is obviously still so confident, and the topics he has studied are really as many as the trees of Nanshan, so he feels that he will not be able to do without him.

"Dr. Kong, this king knows that you are erudite, and it took you about half an hour to calculate this topic just now, which is the fastest among them, but this king tells you that this king only needs ten breaths to calculate this topic.

As soon as these words came out, Kong Yingda was directly stunned.

Ten breaths is good, there is no such person in the world.

He looked incredulous.

"Haha, the prince said that he was joking, how could it be calculated in ten breaths? Xia Guan has been studying this kind of topic for many years, and he can't be so fast.

"Even if the prince is a genius, I'm afraid he can't be so fast, hehe, it's hard to believe it. "

This king knows that you won't believe it, wait for this king to calculate it for you in person, shouldn't this be a fraud?"

At this time, people handed in the test papers one after another, and there were more people who were trapped in a state of blindness, and they didn't know how to answer at all.

After a cup of tea, Zhao Ziyun asked them to stop writing, wouldn't it be a waste of more time if it went on like this.

"Lord Eldest Sun, look at how many people have passed this time, and how many people have not.

Zhao Ziyun asked the eldest grandson Wuji to count the results just now.

"Back to the prince, there are thirty people who have passed, and the other twenty have not. "

Very well, then you make a record of all these people's names.

Then Zhao Ziyun looked at Kong Yingda and said with a smile: "This king just said that the answer will be calculated for you in ten breaths, you can take a look." Zhao

Ziyun's actions made many officials next to him embarrassed, they all calculated for a long time before they figured out the answer, and Zhao Ziyun's words, how dare they believe it.

"Lord Wang, I don't believe it either, so we'll wait and see.

Kong Yingda said lightly.

The eldest grandson Wuji next to him also had a skeptical look.

Zhao Ziyun took a piece of paper and listed the x, y, and z unknowns on the paper.

3x+2y+z=40，2x+3y+z=34，X+2y+3z=24。

Then they jointly simplified and eliminated the elements, and finally the answer was quickly written.

X=10，y=4，z=2。

This move made them all stunned, and they didn't know what Zhao Ziyun wrote at all.

"It's over, do you see if you wrote the answer?"

The masters took Zhao Ziyun's scratch paper and looked at it, all of them looked confused.

"Lord, your answer is right, but we don't understand what you wrote at all, and please give me advice.

At the moment when Zhao Ziyun calculated the answer, they were all shocked, and it was hard to believe that the answer was indeed calculated between ten breaths.

Zhao Ziyun thought to himself, if you can know, it would be strange.

Not to mention anything else, I'm afraid you are all rare in these letters, let alone the solution.

"This is called the equation you are familiar with, but it is just a system of equations, which is a system of ternary equations, and the required answers are written as unknowns, and then written into equations, put together, and can be solved by eliminating elements.

After Zhao Ziyun finished speaking, these people were still ignorant, Zhao Ziyun could only do calculations for them personally, and in the process, he drew inferences from one another, and let them calculate some answers in person.

After that, I saw that the faces of those people were full of admiration, and they were all admired.

"God, my lord, your method has really saved us a lot of time, I have never seen such a quick way to answer.

"What is this? Even the problem that this king gave you before, you can also calculate how much time you will save than using that unknown stupid method, I don't know how much time you can try. After

saying that, someone couldn't wait to start calculating, and sure enough, this time it was even faster.

Whether it is a catch-up problem or a long-term problem, it is quickly calculated.

They were shocked beyond measure, and this was the first time they had encountered such a situation since they started their careers.

After that, Zhao Ziyun once again asked them a lot of questions, including questions such as chickens and rabbits in the same cage, and they were able to answer them faster.

"Now that you've got all the questions in this genre, let's move on to the next one. "
