Chu Tang: Tell Li Er at the beginning that I am a time traveler

Chapter 46 Aren't You Bullying Honest People!

In fact, ancient mathematics is still more 'practical'.

Just like many exercises in the Nine Chapters of Arithmetic, they all have a certain relationship with the real scene.

But just now Li Chong didn't use counting chips, this was Li Er's reminder, and Li Chunfeng discovered it.

I saw Li Er sitting on it, asking in his spare time, "Li Chong, have you finished all the answers?"

Li Chong saluted and said, "Go back to Your Majesty, the answer is over."

Li Er said: "Then what about counting chips? Why didn't I see you, no, you two used counting chips?"

Only then did Li Chunfeng raise his head, his eyes were dazed, and he felt that something was wrong just now.

Because even if Li Chong is a bachelor, then you still have to use calculations.

Even if he came up with the question himself, if he wants to calculate it himself, he must at least use calculation chips.

Seeing Li Chong, he stood upright and said: "Return to Your Majesty, I don't need to calculate. It's just a bit of waste paper."

"Oh? Let me have a look then."

Li Er was very curious, and then a maid came over and took the answer.

Li Er took a look and told the truth.

Those who didn't know, thought that Li Chong was doing tricks, what the hell is this ghost drawing, but in the end, he used words to explain the answer.

So, at least, Li Chong calculated the answer.

Moreover, the rolled noodles are also very neat, but it is a bit incomprehensible.

And Changsun Wuji and the others also became curious at this time. To be honest, which of them didn't learn the art of counting.

only……

They dabble a little, but they don't go deep.

If you ask them to solve a linear equation in five variables, some people may not be able to solve it, like Du Ruhui, they may be able to solve it.

only……

Is it necessary.

Compared with arithmetic, classics such as "Zuo Zhuan" and "Shang Shu" are indeed more important.

Li Er was also very generous. After he finished watching it, he saw that they wanted to read it, so he asked the maid to pass it on.

Fang Xuanling, Du Ruhui, Changsun Wuji, etc. all took them over one by one and took a look at them.

This……

After a look, in twos and threes, they all whispered to each other.

Mainly, they can't understand it at all.

Changsun Wuji asked, "Bachelor Li, what are you writing about?"

"Equation."

The concept of equations existed in ancient times, but the equation Li Zhong said was a bit different from the equation they had in mind.

"You said this is an equation? Why can't we understand a single word?"

Li Chong said quickly: "It's normal that you don't understand, because this is a special way of solving equations."

"Father, I want to see it too."

Li Chengqian almost stood up and asked for it.

Li Er nodded slightly, and then Li Chengqian went to look for his uncle, Changsun Wuji also said: "Prince." He handed Li Chong's answer to him.

to be frank.

Li Chengqian couldn't understand even more.However, the teacher's handwriting has obviously improved a lot in the past year and a half.

After Li Chengqian found out that he couldn't understand it, he ignored it and continued to pass on the answer.

Wei Zheng is actually not interested in this kind of thing.

But now that it has been passed on to him.

Then he opened his eyes slightly and took a look.

Good guy!
What is this pile of ghost symbols?
But don't tell me, although I can't understand it, it is quite beautiful.

and……

It seems very methodical, not really completely blind.

Wei Zheng looked at the answer, and then expressed his opinion: "Since Xueshi Li has already made it, shouldn't it be time to publish the answer?"

Li Chong was not in a hurry, looked at Li Chunfeng, and said, "This brother hasn't done it yet."

Since Li Chong didn't know the other party's official position at the moment, calling him by his name didn't seem like a big deal, so he had to use brother.

Li Chong said so.

Everyone looked at Li Chunfeng.

Li Chunfeng wanted to struggle again, but after thinking about it, he gave up.

After all, at this speed, he is already inferior to others.

But what he said next caused everyone present to be in an uproar.

I saw Li Chunfeng said: "Return to Your Majesty, I can't solve a single problem."

Everyone was dumbfounded.

Even those who are familiar with each other can't help but think, we all know your kid's numeracy skills, and you usually see that you are more agile and faster than us old guys when you place counting chips.

Why, you can't solve a single question?
At this time, Li Chong also hurriedly came out and said: "Actually, it's the minister who won't fight."

Everyone was even more surprised.

Li Er also stroked his beard that was said to be used as a bowstring.

Asked: "What's going on?"

Li Chunfeng and Li Chong looked at each other.

It seems to be communicating, who will speak first.

In the end, the boy Li Chunfeng was given the lead, and said: "Your Majesty will understand after reading the title."

After speaking, he presented the topic Li Chong had asked.

With suspicious eyes, Li Er quickly read the title.

The topic is very simple.

A drawer has silk socks and brocade socks. The possibility of taking out two socks randomly is [-]/[-] of all possible cases. Ask: If the number of brocade socks in the drawer is an even number, what is the minimum number of socks in the drawer? only socks?

This is a proper probability problem, but it is completely beyond the scope of all the arithmetic that Li Chunfeng has learned before.

and……

Looking at this topic, it is completely confusing, and it is very jumping.

It also mentioned the possibility of taking out two socks, why did it suddenly jump to if the number of brocade socks is an even number?

Li Er couldn't help but glance at Li Chong, his eyes seemed to say, it's not that my level is low, but that the question you asked can be calculated by a normal person?

Moreover, this does not give people the opportunity to use calculation chips at all.Looking at the whole topic, only one half is a number, and there is an even number. How to calculate this thing?
And if the first question is unconstrained, then the second question is even more outrageous.

Li Chong drew a square field casually, and drew a parabola in the square field, saying that on this square field, every point corresponding to the length has a unique corresponding point on the width, and also gave In one sentence, explain the mathematical relationship between each other, and then ask, what is the product of the shaded part (below the parabola).

Li Er looked horizontally and vertically. To be honest, he had already begun to doubt Li Chong. Can this thing really be counted?
For the last question, please try to calculate the ratio of pi without using circumcision.

This pi Li Er knows that if a craftsman prepares wheels or something, he must use this to count, and it can't be counted as too much, and it can't be counted as too little. If it is too much, it is a waste. You haven't given me a single number, how can I count it for you.

Li Er pouted at Li Chong.

He couldn't stand it anymore.

Aren't you bullying honest people!

Ask Li Chongdao: "Can this thing really be calculated?"

Li Chong said, "It's a bit difficult, but it can be calculated."

Hearing what he said, Li Er was relieved.

Said: "Let's pass it on, let's all have a look and see who can figure it out. If anyone can figure it out, then I will reward him with a BMW."
