The road was defeated and squeezed, and finally squeezed to the front.

At the front stood a scholar, wearing a silk long-necked shirt with a scarf and a placket, holding a brush in his hand, frowning slightly, as if he was thinking about how to answer this question, but after standing for a long time, he still did not put down his pen.

Someone finally couldn't help but say: "Zhang Shen, can you solve this arithmetic problem?" ”

Arithmetic problems?

Oh...

It turned out to be a math problem.

In ancient times, mathematics was usually called arithmetic or arithmetic, in other words, you Qinglou does not chant poems and lyrics, make couplets, and engage in this kind of math problem, this is not the intention to embarrass others?

You must know that in ancient times, the understanding of the scriptures and meanings was the most important, mathematics was not considered the mainstream, and the employment scope in the system was relatively narrow, and if you couldn't get an official quota, you could only be a personal assistant to officials.

Plainly.

Few scholars delved into mathematics, even though the Confucian regime recognized the existence of arithmetic.

Whoever made the scope of the imperial examination, most of the pen and ink are on the scriptures, and the mathematics topics occupy very little space, and it is precisely because learning mathematics is not of much use, so many readers only learn some generally, and they stop at the beginning and no longer study deeply.

The ability of ordinary readers to recite poetry is far better than solving arithmetic problems.

Moreover, throughout the ancient Chinese mathematicians, they were basically the existence of some rich second generation officials, and most of them studied mathematics just because of their hobby, which also shows that arithmetic was not welcomed among the mainstream scholars in ancient times.

The scholar who was called Zhang Shen, the pen he was holding in his hand, was put back by him dignifiedly, and said with a wry smile: "This question requires mental arithmetic to be solved, which is too difficult for me." ”

Another reader walked over, stood in place, looked at the question, read it slowly, began to filter some pictures in his mind, and began to do mental arithmetic.

The time for a stick of incense has passed.

Fill in an answer and go up.

The little guy watching from the side was illiterate and asked, "This son, what is the answer?" ”

"Three hundred and fifty." The scholar spoke.

"The answer is wrong." The little guy shook his head, "Childe, you can't go up to the second floor. ”

The scholar said angrily: "Isn't this topic just embarrassing us? Who can mentally calculate this topic? You? You? Or are you? ”

The scholar gestured to the onlookers.

"No one can figure it out."

Lu Cheng glanced at it, this reader was obviously irritated by this question, thinking about a question for a long time, and never getting the answer he wanted, people with a poor heart would show some resentment.

He coughed.

"Wait." Lu Cheng walked over, "I might be able to answer this question." ”

The scholar turned his gaze to Lu Shi's body, first clasped his hands, and then said: "Du (du) Yonghuangjing." ”

Introduce oneself.

Introduce yourself first, then your name.

Lu Yu thought about it, and he was not familiar with the wilderness realm, so he reported to the place where the heart and seclusion mansion were located, "Siliu, the road is invincible." ”

When you walk outside, it's better not to use your real name.

If you are recognized, it will not be interesting.

Lu Defeat's eyes looked at Huang Jing.

I wanted to see what this person had to say.

Siliu, Huang Jing sneered in his heart, Siliu is in the Great Chu Dynasty, it is a remote continent of the Great Chu Dynasty, and it is also a relatively inferior continent, he was born in Duyong, and it is the Kyoto of the Dajiang Dynasty.

A poor talent from a poor rural area dares to say such a thing? Solve an arithmetic problem that he can't even answer correctly?

He thought to himself, but his face didn't change much.

"Oh." Huang Jing said with a smile: "I have heard that Siliu Wuhua Tianbao has produced talents, and when I saw that my brother Tai was so stylish, I only sighed that the earth was a masterpiece... It's just that... Dare to ask my brother about Taiwan? What year is the Jinshi? ”

The road was defeated.

According to the normal script, shouldn't this reader come up directly to mock? I actually started to check the household registration book.,It seems that the ancients still have some skills in thick black learning... At least feel the details of the road defeat.

However, Lu Cheng really has no official status.

Even the origins and names in the newspaper are fake.

"I'm ashamed, I don't have an official body, but I'm too lazy to talk nonsense with you, I can solve this problem." Lu Shi said simply and rudely, but also very bluntly.

This made the Yellow Vistle silent.

Don't say it.

In this way, Huang Jing, who originally jumped and wanted to say a few words to kill the road defeat, suddenly felt that he had nothing to say, everyone was frank and open, and he spoke so bluntly, what else could you do?

Huang Jing was said this, so he could only stand to the side.

But it's still a slander in my heart, this shouldn't be a person who hasn't read a book to solve the problem, right?

He has already done a good job of saying that he can't answer the question when he loses the road, or if he answers the wrong question, and he comes forward to 'comfort' (poke the sore spot).

Just when Huang Jing was still preparing to speak with a full stomach, Lu Wei gave his own answer.

Ancient arithmetic problems?

Talking about arithmetic in front of a traverser?

You despise my Great China tactics a little... Moreover, in modern times, the questions of junior high school students are already considered top problems in ancient times, and you no longer belong to the tactics of despising Greater China.

You are a primary school student who despises me in the red fruit land.

Bah!

Even with contempt for road defeat.

As a college graduate, even if the math score has always been at the bottom, but solving math problems at this level is not the same as playing home?

Bring the calculus of the modern era.

I'm afraid you're not mentally exploding.

And the title on this blank piece of paper is very simple.

"A scholar lives in Daoshui Township, and when he travels to a private school at home, he needs a stick of incense..."

Translated into Chinese, there is a scholar who lives in a place called Daoshui Township, and it takes 30 minutes to walk from his home to the private school (the time of one incense is about 30 minutes), and the average walk is 76 meters per minute. Because today he has to discuss the scriptures with Mr. Teach, he needs to go to the private school 10 minutes in advance, if the departure time remains the same, then how many meters will he have to walk per minute?

You only need to calculate the distance from the student's home to the private school, multiply it by 76 meters per minute, and then divide it by 30 minutes to 10 minutes, because you have to arrive at the school 10 minutes earlier.

That is, the total distance of 2,280 meters divided by the time of 20 minutes gives 114 meters per minute.

The topic is simple.

Topics for the first grade of primary school.

But to do mental arithmetic, the ancients did this kind of problem, if you rely on mental arithmetic alone, it is still quite difficult.

Lu Shi has a computer APP in his head.

Fill in the thoughts, and the answer will be answered in one breath.

Hearing Lu Defeat's blink, he answered the answer without even thinking about it, Huang Jing was overjoyed in his heart, and was ready to wait for the little guy's refusal, and planned to sneer fiercely.

The little guy on the side said in surprise: "Congratulations to this son for answering the correct answer, this question is amazing, no one has answered it for a day, right... Ask Childe to move to the second floor and leave another question for the next test. ”

(Ask for recommendation votes, the back is more exciting.) ）

(I saw it all in the comment column, and I answered them one by one in the book.) ）
