Lu Huang pondered his wording for a moment, and then rephrased it: "Well, sports is a kind of education for the body, and sports venues, to put it bluntly, can be said to be a place for physical activity, as if you haven't seen it?" ”

Yes, Lu Huang is talking about sports venues.

Deacon Gao naturally understood this time, and he was a little stunned: "Our school is a place to learn knowledge, and there is no need for physical activity." ”

After listening to Deacon Gao's words, Lu Huang understood, this is dead reading, it seems that the ancient primary school students were very hard, going to school, in addition to reading and reading and literacy, where is there a little time for recess activities?

Lu Huang was very sympathetic to the ancient primary school students.

Lu Huang stood in the courtyard, his expression extremely serious.

The afternoon sun shone on his body, bringing him a warm feeling.

With such good sunshine, wouldn't it be a waste of time if children couldn't enjoy such good sunshine if they were reading indoors every day?

Lu Huang turned his head at the moment and said to Deacon Gao word by word: "This sports must be carried out, not only must we include sports in our daily study schedule, but we also need to invite a physical education teacher." ”

Deacon Gao really didn't understand the importance of the "sports" in Childe's mouth, but Childe was the master, and it was just a matter of listening to it, so Deacon Gao bowed and said yes.

The three of them returned to the hall.

Shuangxiu and Deacon Gao were standing. Lu Huang sat down first, and when he saw Deacon Gao standing on his own, he beckoned Deacon Gao to take a seat as well.

Seeing that Gongzi was so approachable, Deacon Gao felt very honored and sat down.

But after all, I know that there is a difference between master and servant, and there is also a deep-rooted gap in my heart, so although I sat down, half of my ass was still hanging outside, but I didn't dare to sit down.

Lu Huang asked Deacon Gao all aspects of the school, and Deacon Gao saw that Gongzi asked a good question, and he also replied conscientiously.

While the master and servant were talking, a servant came in outside to report that the three teachers had come together.

Deacon Gao looked at Lu Huang and asked, "Childe, let the three of them come in together?" ”

Lu Huang thought for a while: "No, come in one by one, I'll talk to them in detail." ”

Deacon Gao answered, but he didn't know which teacher Gongzi wanted to let the teacher come in first, since Gongzi didn't explain, he waited for Gongzi's specific explanation.

Lu Huang knew that the three were Mr. Article, Mr. Arithmetic and Mr. Poetry.

In Lu Huang's opinion, the article and Mr. Poetry do not need to be separated, they should be regarded as a subject of language.

But it seems that in ancient times, poetry was very high, so it will be listed separately.

Lu Huang thought about it for a while, and he said to Deacon Gao, "Let's invite that arithmetic master to come in first." ”

After the high deacon stepped down, he soon brought in the arithmetic master Wu Guang.

That Wu Guangren was thin and short, and his voice was not too high, and his brows were always locked, as if he was calculating some difficult problem in his mind at any time.

After Lu Huang was in the cold noise, he went straight to the point.

Lu Huang asked, "Mr. Wu, do you have strong computing skills?" ”

Wu Guangdao: "Everyone is the same algorithm, I'm just because I'm immersed in it, so I'm faster than others, and I'm only proficient." ”

Listening to the other party's tone is very humble, Lu Huang likes such a humble person.

Lu Huang said: "Then I will come up with a question, and I want to ask Mr. to try to solve it." ”

When Wu Guang heard Lu Huang's words, his heart immediately became nervous.

Because the three teachers have had a very full exchange on the way to the school.

They knew that the Lu family had changed masters.

Lu Gongzi is now young and in charge.

Invite the three of them to come, although they didn't say any reason, the three of them also roughly speculated that this is the son who is going to interview the three, and if he thinks he is qualified, he will stay, otherwise he may be invited to leave.

None of the three wanted to lose the position.

After all, the salary offered by the school where the Lu family presides over the overall situation is quite generous, and it is also very high in the industry.

If you are resigned by the Lu Family School, it may not be easy to find a teaching position with the same salary.

Besides, the literati want to save face, if they are resigned by the master's family, or because of their professional ability, their faces will be dull, and their faces will be beaten.

Now that he tried it, he bred up and gave it his all.

Lu Huang made such a question: "Excuse me, Mr. Wu, how much does this twenty-five by twenty-five get?" ”

He was curious about how people of this era could calculate simple multiplication of multi-digits.

When Mr. Wu heard this, he immediately got busy.

I saw him take out a small box from his bosom and open it, and there were two things in it, a piece of paper and some small log blocks.

Lu Huang was very strange when he saw it, what kind of chess is this?

But Go is not like Go, Xiangqi is not like Xiangqi, is it a kind of ancient rare chess that I have never heard of?

The gentleman spread out the piece of paper, and Lu Huang opened his eyes wide with curiosity to see that it was a table with several squares, and each square was divided into two triangles of equal area, and the diagonal lines that were divided were drawn from the top right to the bottom left.

Lu Huang was even more puzzled in his heart, he didn't know what this Mr. Wu was doing.

Then Mr. Wu chose two columns for the table on the paper, and placed two and five sons respectively at the top of the top two grids.

And on the right, two lines were chosen.

Mr. Wu first put 4 pieces in the lower triangle of the row of grids in that column. On the second row of the triangle put 1 sub. One column and two rows put 1 child on the triangle, and two columns and two rows put 2 seeds and 5 children respectively.

Then Mr. Wu tilted the paper 45 degrees, made a simple motion, and put the three columns into three piles, and counted them separately.

That's 6 sons, 2 sons, and 5 sons.

Lu Huang silently replaced the number of subs with numbers in his heart, and he quickly understood that this was a variant of the modern vertical style.

Mr. Wu quickly reported: "Childe, it should be six hundred and twenty-five, right?" ”

Lu Huang, of course, he had already calculated it in his heart.

Seeing that Mr. Wu had answered the correct answer now, he nodded.

- But it turns out that this is how the two-digit multiplication method was done in ancient times, which is interesting.

Take a deep breath, the second course is coming!

"Mr. Wu, erect a flagpole in the open space, how can you measure it?"

Mr. Wu was a little confused, this question is strange. Mr. Wu thought, "I can climb up with a ruler and measure it." ”

Lu Huang said: "This method is very stupid, but there is another good method?" ”

Mr. Wu was at a loss as to what to understand.

Lu Huang smiled: "Well, this question is not important, just use it as an additional question." ”

Then he went back to the previous question: "This kind of question is the one that is fundamentally important." ”

The difficulty of this additional question was too great, Wu Guang heard Lu Huang say that his answer was not good, he racked his brains, and he couldn't think of a better way in a short time, so he couldn't help but break out in a cold sweat.

Now I heard Lu Huang say that this question is not important, the important thing is the basic calculation problem, he hurriedly got off the donkey, and echoed in a loud voice: "Son, you are very right. ”

"Mr. Wu, I can see that your computing skills are quite strong." Speaking of this, Lu Huang paused for a moment, and then changed his words again, "But in my opinion, it's still too troublesome." ”

As he spoke, he pointed to the little things that were used as operators, and the piece of paper that was covered in grids.

Isn't even this basic problem the optimal solution? When Mr. Wu heard Lu Huang say this, his cold sweat broke out even more, and he felt that his position as a teacher was a little precarious.

So he stretched out his hand and wiped his forehead, staring at Lu Huang tightly without blinking.

Lu Huang took a few operators in his hands, rubbed them, pinched them, and checked them again, and then he said with a smile: "At present, I want to say that I think the optimal solution is only so far, but this is a bit long." ”

In order to explain to Mr. Wu the more advanced Arabic numeral column calculation method, Lu Huang first had to explain to the other party what Arabic numerals are, that is, the renamed "Lu Huang numbers".

So Lu Huang picked up the pen and paper and told Mr. Wu eloquently.

The same Arabic number problem, this is the second time Lu Huang has told people. The first time was to give a lecture to Sun Yong in the account room.

And this time I talked to Wu Guang and I told Sun Yong before that it is completely two different concepts.

Sun Yong's main idea was that he felt that Childe's doing this was a bit redundant, and he even thought that Childe was a bit willful to invent this number for his own convenience.

But Wu Guang is different. He is a professional arithmetic teacher, and he has been in this industry for so long, of course he knows how much progress Lu Huang's pioneering move has made to improve the calculation speed.

When Lu Huang used Arabic numerals to list the vertical calculations of 25×25 to him and explained them in detail, Mr. Wu's inner emotions were tangled and tumbling and difficult to decompose.

He looked at Lu Huang with the eyes of a celestial person, his hands holding the paper were trembling violently, although he did not fully grasp the details such as the carry in the meantime, but he knew in his heart that this was simply a milestone leap!

Lu Huang didn't pay much attention to his eyes, he casually took out a blank piece of paper from the side, took a pen and wrote three two-digit multiplied by two-digit calculation problems on it.

Then he copied the blank piece of paper and faced Wu Guang head-on: "What about these three questions, you can take them home and do them, you must do them in my format, not in your original way, do you know what I mean?" When you're done, you'll hand it over to the school tomorrow by this time. ”

Wu Guang understood that this was an assessment of himself, but the nervousness in his heart was far less than his excitement, because he thought that even if he didn't pass the assessment, he had mastered this magical calculation technique, and he could shine anywhere.

Go mix him up with a big bowl of rice to eat!

Lu Huang felt that everything was almost done, he stood up and gave it away, and said to Wu Guangyi: "Mr. Wu, I hope you can get a perfect answer sheet tomorrow." ”

Wu Guang listened to Lu Huang's words, which proved that this was a decant exam paper, so he said with sincere fear: "Childe, I will do my best, do my best!" ”

Then he turned and walked away.

Here, Lu Huang had already asked Deacon Gao to ask the teacher who taught the article to come over.

The two teachers met in the corridor, and the teacher who taught the article hurriedly pulled Teacher Wu's sleeve and asked in a low voice, "How is it, what is the situation?" ”

Teacher Wu felt that it was difficult to explain the situation inside for a while, so he smiled bitterly and only said: "Be careful!" ”

After saying this, there were no more superfluous words, and he walked away with a black line.

He has to hurry up and go back, so that he can study those questions, as for the additional questions, it depends on the situation, if he can rush again, of course it is the best!

Teacher Li was very apprehensive in his heart, seeing that Mr. Wu's expression was so strange, he kept circling the phrase "deal with it carefully" in his mind, what does this mean, to tell himself to be both "careful" and "cope".

Be careful of what?

What to deal with?

is worthy of being a Chinese teacher, and immediately began to chew the words.

Lu Huang spoke about Arabic numerals again, feeling that he had a feeling of "being a good teacher", and he felt a little proud in his heart.

Finally waited for another teacher, Mr. Li.

Lu Huang politely asked for a seat.

Lu Huang went straight to the point: "Mr. Li, what about me, I have some questions about the article, let's talk to you." ”

Teacher Li is smart, and people will understand as soon as they hear it, this son is polite and polite to learn from himself, but in fact, he is here to test himself.

Lu Huang scratched his head and said: "What about this teaching, the amount of knowledge can be obtained, does Mr. think this is the truth?" ”

Teacher Li nodded again and again: "Yes, yes." ”

I thought, you're Dong Weng, whatever you say is.

Lu Huang smiled and asked: "People often say that there are three disasters on the grassland, do you know which three disasters they are?" ”

Teacher Li knew this, so he immediately replied: "There are white disasters, black disasters, and yellow disasters." White plague, heavy snow covers the grasslands, and there is nowhere to graze. Black plagues, plague pandemics, mass deaths of livestock. Yellow plague, sandstorms suddenly rise, and the sky and the earth have no color. It is called the three plagues. ”

That's right. Lu Huang has another question: "Squandering, if the word is decomposed, what does it mean?" What does Huo mean? ”

Teacher Li obviously will, he didn't think about it, and immediately replied: "Shake your hand to wave, and your backhand is Huo." ”

Lu Huang nodded again, he saw that Teacher Li had answered correctly, and he was ready to increase the difficulty a little.
