Xueba, I beg you to go and escort him quickly!

"Without studying during the winter vacation, it's terrifying that she can progress to this level just because of Xu Heng's last semester and the one-on-one tutoring this semester..."

"Xu Heng, what kind of monster are you!"

Xue Laiyun didn't want to have such a reaction, but Naihe simply couldn't help it.

"Hey……"

When Yue Pingting came back from the office, she went to Xu Heng's side, "Xu Heng, the class teacher, found a problem for me to do, and then he was in a daze? It's a bit inexplicable..."

Xu Heng, "What question?"

0 ......... 0

Yue Pingting briefly described it.

Xu Heng smiled, "This question is a college entrance examination question. The teacher in charge will test you, so I'm afraid they know how good you are."

Yue Pingting, "!!!"

She chuckled.

I am delighted.

"Thank you Xu Heng! Hehehe..."

It wasn't until the Chinese class that Yue Pingting regained her inner excitement.

After Yao Ruiyi came to class, the teachers at the end of the classroom were still there.

The previous math teachers also stayed behind.

Yao Ruiyi, "???"

She and Xue Laiyun have the same expression and the same thought.

What do these teachers mean?

Why didn't you leave?

Math class is over!

Bite the bullet, Yao Ruiyi started her own class.

She found another way, starting with the story, because what she was going to tell today was the classical Chinese with the same pronunciation that he had asked Xu Heng for advice.

"Everyone knows that since the failure of the Opium War, my country became a semi-colonial and semi-feudal society at that time. Under the long-term colonial rule of Western countries, the comparison between Chinese and Western cultures lasted for decades, and Western ideology and culture washed away like waves at that time. nation's mind."

"People in the country at that time kept reflecting on whether it was the old traditional culture that caused our country to be so backward and corrupt, and that led to the people being bullied at that time. For the purpose of patriotism, a wave of sweeping away the old culture began in the country, and the old culture Everything in China is inseparable from Chinese characters, and to sweep away the old culture, we must abolish the thousands of years of Chinese characters in our country.”

"At that time, some literary masters said: If Chinese characters are not destroyed, our country will be destroyed!"

"In this way, a vigorous campaign to abolish Chinese characters began."

"When a new idea is put forward, if there are supporters, there will definitely be opponents."

"This was unavoidable under the circumstances at the time. The supporters believed that there were a lot of Chinese characters, and even the fonts and writing methods of the characters had their own masters, and there were many forms."

"..."

Yao Ruiyi laid the groundwork a lot, and the students' interest came.

She watched her classmates staring at her intently, and she finally got to the point.

"Mr. Zhao, among the opponents, even wrote two anecdotes through the ages in 1930. The whole text is a word with a different pronunciation, in order to refute the idea of ​​abolishing Chinese characters. These two articles are the famous "Ji Ji Fighting Chicken" "Records" and "Shi's History of Lion Eating."

"A full text is in ji, and a full text is in shi. If you really read it all in Latin, you will not be able to understand the plot of the story at all."

"Next, let's learn these two classical Chinese essays."

Saying that, Yao Ruiyi said, "The class representative will send the two articles I prepared, one copy for each..."

Yue Pingting stared at it, stunned for a moment, and then murmured to Xu Heng, "Isn't this the classical Chinese essay Mr. Yao asked you about last semester?"

Xu Heng, "???"

He doesn't remember.

"You forgot, it was the time when you were playing games at home and asked me to help you translate and send it to Teacher Yao."

Chapter 297

Come down all morning.

There are many teachers at the end.

Twenty or thirty people!

There have always been twenty or thirty people!

Not a single one ever left.

Until school is over at noon.

Xu Heng and Yue Pingting had lunch together, and the group of teachers went to eat at the place arranged by the school, and they separated.

Yue Pingting said, "Huh... Finally, there are no more teachers!"

"Huh... really Alexander!"

Just as he was complaining, Feng Nianshang ran over and looked at Xu Heng and Yue Pingting with envy and excitement in his eyes.

Yue Pingting smirked, "Sister..."

Xu Heng, "???"

He looked left and right, not knowing what the two girls were thinking.

Feng Nianshang also smiled at Yue Pingting.

"Forehead……?"

Feng Nianchang looked at Xu Heng later, "Xu Heng, you have taught me a great girlfriend!"

Xu Heng, "What do you mean?"

Feng Nianchang explained, "Originally, I had a question I wanted to ask you for advice last night, but the question fell to Xiaoyuezi, and then there was nothing else, and then Xiaoyuezi solved it."

Xu Heng smiled.

That's what happened.

"That's natural. She is very good now, and the college entrance examination questions are no longer difficult for her."

Yue Pingting still smirked.

Feng Nianshang took a deep breath, "So, Xu Heng, what kind of monster did you raise Xiao Yuezi into?"

"You're only a sophomore in high school, okay? You're too advanced!"

Xu Heng looked at Yue Pingting, "You know a lot, don't you feel very comfortable?"

Yue Pingting nodded.

Feng Nianchang, "%￥#@￥%..."

You are both showing off and showing affection.

"Hey……"

She sighed resentfully.

Yue Pingting said, "No matter how good I am, that's it! Besides, the two questions they did were written by you, Xu Heng, and they were taken away by the math teachers."

Xu Heng, "Uh..."

Fine.

Chatting and chatting, anyway, the topic can always come back to myself.

And Feng Nianshang didn't come over to greet them.

"I have a question to ask you guys!"

Yue Pingting, "Sister, tell me."

Feng Nianshang stretched her neck, looked at Xu Heng and Yue Pingting, and asked, "Do you think that the cycle of a is equal to 1?"

Yue Pingting's first reaction was, "It's definitely not equal! Even if it's recycled, it's smaller than 1! What do you think, Xu Heng?"

brush!

Look at Xu Heng.

Xu Heng nodded.

Yue Pingting froze, opened her mouth wide, "Huh?"

She looked at Feng Nianshang again, "Sister, is Xu Heng right?"

Feng Nianchang curled his lips, nodded, and then asked, "Why?"

Xu Heng was indifferent, and said while eating, "Isn't this common sense? Oh no... This is already against common sense..."

"Or, counter-intuitive..."

"This thing appeared in Euler's "Elements of Algebra" in 1770 yesterday, but the issue that the cycle of is equal to 1 has been debated by mathematicians for hundreds of years. Now, many people still don't believe this conclusion, such as you."

Yue Pingting blushed, "Ah..."

Yue Pingting scratched the back of her head, "I don't understand! It's obviously not equal!"

Xu Heng smiled, "This question is actually asking whether these two numbers are equal. From an intuitive point of view, the 999 cycle must be less than 1, because the 99 cycle is infinitely approaching 1, but approaching 1 means that it has never been reached. 1, since it does not reach 1, it must be smaller than 1, which is also very consistent with our common sense.”

Yue Pingting almost stood up and patted the table to applaud.

"That's right! That's what I think!"

"That's right!"

"Senior sister, you see that Xu Heng has said that! So it should not be equal!"

Feng Nianshang, "Xiao Yuezi, are you confused again, Xu Heng said it was equal before."

Yue Pingting was confused in an instant, "Uh..."

She frowned, "So what is it?"

Xu Heng looked at Yue Pingting and smiled, "Nizi, you said that the cycle is smaller than 1, so tell me, how much smaller is the cycle than 1?"

Yue Pingting, "I... this... an infinite loop... eh, no, countless 1s after the decimal point..."

"Ah! I'm running out of brains."

Xu Heng smiled, "So, you will find that you can't answer this question. It seems that you can't answer how small it is. The reason is that the number of 9 cycles is followed by an infinite number of 9s. Once the concept of infinity is involved in mathematics, it will take away The problem got more complicated."

"We know that if there are a finite number of 99s after 9, then we can definitely assert that this number is less than 1, but there are infinite 9s, which is not necessarily the case. We judge whether two numbers are equal, in fact, mainly by comparing the two numbers. Subtract to see how much the difference is."

"If the difference is not equal to 0, it means that there is a gap between the two numbers, and the two numbers are definitely not equal."

So... to count...?

???

Yue Pingting and Feng Nianshang looked at each other, and finally stared at Xu Heng.

The other students in the cafeteria all looked sideways, envious.

The two beauties in the school circle around Xu Heng at the same time!

It's really cool!

"When will I be able to become like Xu Heng?"
