Although the nine-nine multiplication table looks strange, its formula is not surprising. There were multiplication formulas in the ancient Spring and Autumn Period.

However, the nine-nine-nine multiplication table is summarized in the form of numbers, which is clear at a glance and easier to learn.

Use 0, 1, 2, 3... instead of one, two, three...

Use +, -, x, /... instead of addition, subtraction, multiplication, division...

Make the calculation form more simplified, clearer, easier to express, and convenient to calculate complex calculations.

After talking about the "Nine-Nine Multiplication Table", everyone can understand it.Zhang Liang said: "Addition, subtraction, multiplication and division are all understandable to everyone. Next, we will use this new number to perform complex calculations."

Speaking, Zhang Liang wrote on the blackboard: 568-124/18*(1589+2763-4316)+58*96=

After finishing writing, he said: "Everyone, please take a look. This is the advantage of the new number. It can better express the complex calculation form. As I said before, the principle of sequential operation that needs to be followed... This question, do it first. "

"A lot of numbers, I feel dizzy looking at it!"

Chen Que, Shangshu of the Ministry of Etiquette, raised the pen and started to do the question, thinking: "When there are brackets, first count the brackets. If there is a multiplication and division in the brackets, first calculate the multiplication and division, and then calculate the addition and subtraction..."

Many people are not used to new calculation methods, such as:

58

x96

-------

Some people simply use an abacus to calculate.

On the front wall of the hall is also hung a modern clock, which is not too big or too small, with numbers on it. After adjustment, it basically corresponds to the time of the Chinese Empire.

Zhang Liang checked the time. Officials need to focus on government affairs, and the time to participate in this training course is limited.

Depends on the time coming, and before everyone can calculate the answer, Zhang Liang first wrote the answer to that question on the blackboard, and then said: "The time is coming. I will write the answer first. If I don't understand it, I will write the answer first. Explore."

He picked up more than 20 question papers on the podium table and continued: "I have prepared some questions and sent them to you. After I go back, I will take time to finish them. I will hand them in next time. I will change them one by one."

According to Wang Yu, these question papers are "homework" for officials participating in the training course!

Just as Zhang Liang distributed the question papers, Daming Wang Wangyu came to the podium.Everyone immediately sat in awe, awe.

"Since you entered this training class, you have been very active and worked hard to learn new knowledge. This Wang is very pleased."

King Wang Yu of the Ming Dynasty said in a serious way: "This king knows that there are still some people among you who are still wondering and questioning why they should learn these Western knowledge. They may even think that this kind of behavior is insulting to China, and does not admit that these things are better than China's. ..."

In this era, most scholars reject Western culture.In their view, the so-called science in the West is nothing more than fallacies and heresies, opportunistic tricks, tricks and so on.

Even among these people, many believe that the replacement of Arabic numerals with Chinese numerals is a trick, and the principles of the two operations are basically the same.

Observing the changes in the expressions of the observers, King Wang Yu of Ming Dynasty continued: “In the eyes of this king, as long as it is a good thing that benefits the Chinese Empire and benefits the people of the world, we must recognize its superiority. No matter where it comes from, All should be humble to understand and learn, and finally transformed into our own things.

Today, the king explained his words.If someone can't accept it, he says to leave this training class early.This king promises that it will not be difficult and free to decide.

However, if you are determined to stay, you must go all out and learn it well!"

Everyone looked at each other and dared not say anything.They couldn't believe that if they left the training class, Wang Yu would not settle accounts after the fall.

If you don't like it, you have to endure it.

"Well, it's dusk, let's go back."

Ming Wang Wang Yu finally reminded: "You can teach others what you have learned here. If you meet someone with outstanding talent in this area, you can recommend it to this king. If you are thirsty for talents, this king will be rewarded many times."

Nowadays, most of the famous civil and military of Daming have gone to the Nanming court, so there are not many celebrities in Wang Yu's hands.

However, Wang Yu wants to cultivate new talents by himself.It turned out that Da Ming’s famous people, although talented, have limitations. I am afraid that most of them have difficulty accepting new things.

Holding this "training class" is an attempt, but it is far from enough.

...

The second day.

Today is the first day of the imperial examination of the Chinese Empire, and the capital is very lively.

There were more than 600 people who came to participate in the scientific examination. This is the result of relaxing the requirements, otherwise most of the people will be the first.

In this scientific examination, whether you are a candidate or not, as long as you meet the basic requirements of eighteen years old and have no criminal record, regardless of gender, as long as you think you are talented, you can come to take the scientific examination.

There are fifty or sixty of these candidates, but this is not unusual.

"I didn't expect that a woman would actually come to take this scientific examination."

This was what surprised the King of Ming and Wang Yu.

"According to the registration, a total of nine women came."

Zhang Liang also paid special attention to this.

In this era of examinations, the registered information is only a rough outline, and cannot guarantee the full authenticity.Therefore, there is not much information about the nine women.

...

Chapter 115: What's the live broadcast? Why don't you come over?

In the historical chat group.

There were only a few people online. Among them, Tang Gaozu Li Yuan said: "Recently, the historical chat group has become more and more deserted. Are they busy with things?"

At the same time, he asked the online group leader Wang Yu: "You are the group leader, why don't you speak?"

Wang Yu is in the imperial examination room in the capital of China Empire, observing the students entering the examination room.

He is online, so he can naturally receive what Tang Gaozu Li Yuan said.

Replied: "I am holding the first scientific expedition of the Huaxia Empire here. Don't be careless about this."

Before the students enter the examination room, they will be checked, and then they will get a number plate made of bamboo, and find their seats according to the number plate.

There were guards from the guards inside and outside the examination room, and the atmosphere was so severe that a few candidates who were too nervous suddenly collapsed on the ground and could no longer take the scientific examination.

"The first imperial examination of the Chinese Empire of the group leader, has it begun?"

Tang Gaozu Li Yuan was a little envious, thinking of his first imperial examination last year, heartbroken.

Everything is difficult at the beginning. It was the first attempt for Li Yuan to implement a relatively perfect imperial examination, so he was blocked by the family and the family.Unlike the imperial examinations of the Chinese Empire, they were all mature and deeply rooted in the hearts of the people.

The group leader Wang Yu said: "The imperial examination was established in the Sui Dynasty and developed and perfected in the Tang Dynasty. The predecessors planted trees, and the descendants enjoyed the shade. The imperial examination system is still applicable in the Chinese Empire."
