Rising: Ten Thousand Years Chapter 6: : Wisdom is close to the demon

Teacher Wang sighed: "Liu Quan, in order to prove whether the answer is right or wrong. How about this, you tell the answer of your calculation."

Liu Quan wiped off his sweat, picked up a pen and busily performed calculations on the white paper, putting various vertical formulas and formulas inside.

After about two minutes, Liu Quan said weakly: "X=10. But I calculated the answer myself. There must be something wrong with Li Zhen's answer. He is sure to know the answer in advance. For such a difficult question, he How could it be calculated in an instant."

Li Zhen sighed, and finally explained helplessly: "It's not that the question is difficult, it's that people are stupid."

"You... you scolded me."

"Primary school level questions, mental calculations in an instant, are you really surprised?"

Li Zhen shook his head and said with emotion: "Mathematics shouldn't be so complicated. The core is to find complex answers in a simple way. But you think the questions are too difficult. Just a score, let you It’s difficult to write vertical formulas on paper, and keep counting the results with your fingers. In fact, if you solve the problem in a different way, you can answer it in seconds.”

Teacher Wang looked at Li Zhen curiously: "How did you solve it."

Li Zhen said blankly: "8.5+65%X=15. Why do you need to calculate the fraction so complicated? You can convert 65% into 0.65. Then this question is: 8.5+0.65X=15 .Subtract 8.5=6.5 from the known answer 15. It is known that the number before X is 0.65, so... how many times 0.65 will equal 6.5? The answer is 10.”

“…”

The audience was silent. Everyone looked at each other in blank dismay. Even the math teachers looked at each other in astonishment.

Is it that simple?

Liu Quan was a little lost: "Ah, yes, 65%, it can be converted into 0.65..."

The students all took a deep breath. This is considered to be learned, and can such a simple calculation method be used?

"What is his brain made of?"

"With such a solution, it feels so simple."

"Isn't it too powerful? This is definitely not cheating."

"Not like."

“…”

There was no disturbance in Li Zhenxin's heart. He put the one hundred coins into his pocket and said to Liu Quan with a smile: "In order to satisfy your wish, I decided to give you a formula."

Liu Quan widened his eyes and asked, "What formula?"

"It's a formula that you were all curious about just now. How did I solve the math problem on the test paper."

"Speak quickly."

“…”

Everyone pricked up their ears, very curious about Li Chen's question just now.

Li Zhen smiled lightly and said, "That question is about the multiplication and division of fractions. Logically speaking, the calculation is very complicated and difficult. But there is a method that can make the addition, subtraction, multiplication, and division of all fractions easy. Easy to understand."

"That method is called 'fractional split method'."

After the voice fell, Liu Quan grabbed the test paper in a panic, carefully looked at the calculation formula left on the test paper when Li Zhen solved the problem on the test paper, and said in a trembling voice: "What is the fractional method?"

Teacher Wang and other math teachers also surrounded him and looked at Li Zhen excitedly: "Tell me quickly, what is the method of splitting items?"

"I've never heard of such a method, what is the split method?"

"Is the split item method your reliance? You write the test paper so quickly, and the answer is 100% accurate. Is it the split item method?"

"Say it quickly, don't be tricky."

“…”

The school leaders also gathered around and looked at Li Zhen attentively.

Li Zhen said lightly:

"There is a very interesting phenomenon in fractions. If the numerator of a fraction is the natural number 1 and the denominator is the product of two adjacent natural numbers, the fraction can be written as the difference between two fractions. The two fractions The numerator is still the natural number 1, and the denominator is two adjacent natural numbers.

In fractions, such a method can be used to simplify calculations that seem very complicated and difficult to understand. It was clear at a glance, and the answer was instantly calculated in the mind.

This is called split item method! "

“…”

After listening to Li Zhen, more than half of the students were in a fog and couldn't understand what he was talking about.

However, some students who are good at studying start to calculate on paper with puzzled faces. Liu Quan also picked up the pen and paper, asked himself a question, and then started to calculate using the split-term method mentioned by Li Zhen.

Not only the students who studied well, but even the school leaders and math teachers began to silently perform calculations.

'Shushasha'

No one spoke in the field, only the sound of paper and pen rubbing against each other.

Five minutes later, Liu Quan put down his pen, stood up and bowed to Li Zhen:

"I was wrong."

‘Wow’

The classmates who didn't know the truth looked around in a daze. Liu Quan, whose family was extremely wealthy, and Liu Quan, who was defiant, actually bowed and apologized to Li Zhen in public?

What is the situation?

A moment later, Mr. Wang slumped on the chair, wiping the cold sweat off his forehead, "Monster!"

"You are a monster!"

"Mathematics, how can you still play like this?"

"The method of splitting... is this the method of splitting?"

"Amazing!"

With a 'buzz', the scene exploded instantly.

Students who have studied well have also tried this new term-the method of splitting.

Everyone felt creepy, and everyone felt completely chilled. Looking at Li Zhen's eyes is like looking at a monster.

"How can he do this? Is this the way he invented?"

"The addition, subtraction, multiplication, and division of fractions is very difficult to calculate. Just the various conversions between the denominator and the numerator are a headache. How can he invent such a method to perform calculations?"

"The method of splitting items is indeed as its name suggests. It is a method of splitting each item and calculating in sequence. The method of splitting items."

"This is simply a mathematical genius. In the history of the Kyushu Empire, no one has ever proposed such a calculation method."

"He has been pretending to be a pig and eating a tiger before, and he has never been a showman. It turns out that his knowledge is so powerful."

"This Li Zhen is not only rich in knowledge, but what is terrifying is that he can actually invent new calculation rules?"

“…”

Everyone felt terrified. Looking at the ragged and thin man, they felt that he was extremely tall at this time.

Split item method!

Teacher Wang shook his beard and said, "How did you know this... this great calculation method? Who did you learn it from? Could it be that you created it yourself?"

Li Zhen smiled but didn't speak, didn't answer, and didn't speak.

I sighed silently in my heart. This is elementary school mathematics from 10,000 years ago, and the mathematics in my subject is actually not good, compared to...

Now that the new calendar is 10,000 years old, there are so many gaps in basic disciplines?

He felt a little sad for the world.

But at the same time, I feel that the burden on my shoulders is getting heavier. Maybe I have the obligation to spread the knowledge I acquired crazily there, the basic disciplines 10,000 years ago, to this barren world today...

The chemistry teacher also took this opportunity to ask:

"I would like to ask classmate Li, there is a question on the test paper about the way to get oxygen. In the field we know, there are no more than two ways to get oxygen. The first is electrolyzed water, and the second is high manganese Potassium acid heating... And you, what is the meaning of this formula left behind? Based on the incomplete periodic table of elements left in ancient times, if I remember correctly, this formula should be the formula for extracting sodium acetate, right? What does it have to do with oxygen?"

Li Zhen asked: "If I remember correctly, is this question asked like this: How to extract oxygen faster and more conveniently?"

"Yes. That's the question. This question is mainly inclined to rapid oxygen production, and it is a question with a bit of a brain teaser. Because of the two known methods of electrolyzing water and potassium permanganate heating , Heating potassium permanganate obviously can get oxygen faster. Heating potassium permanganate and filtering it through water can..."

The chemistry teacher was talking endlessly, but Li Zhen interrupted:

"In addition to this, there is a third way to produce oxygen faster. Adapting to the question type is mainly about speed and convenience, so... 2Na2O2++O2."

The chemistry teacher asked in surprise: "What does this mean?"

"Sodium peroxide and carbon dioxide react with each other to generate not only sodium carbonate but also oxygen. Because carbon dioxide is a common greenhouse gas, only sodium peroxide is needed. That is to say, sodium peroxide Gas, it can produce oxygen without any operation. It is faster and more convenient. Because the two react to generate oxygen, you can carry it on your body at any time...follow the question type. Electrolyzed water to produce oxygen, can you wear the device at any time? ? Potassium permanganate reaction, can you always carry a beaker, water, and potassium permanganate test tube?"

"Can't."

"So, it is more convenient and quicker to produce oxygen. So it is equal to ~IndoMTL.com~ I only heard Li Zhen's voice echoing in the auditorium, all the teachers were collectively petrified, and all the students looked at him with god-like eyes .

Holding your breath, no one dared to make a sound for a long time.

A moment later, a chemistry teacher took sodium peroxide and exposed it to the air for observation.

Someone exclaimed: "Oxygen is really generated!"

"Ah, my God, it really will."

"I used to know that sodium peroxide meets carbon dioxide to form sodium carbonate. But many people use this method to extract sodium carbonate. How come no one has discovered that this formula can also generate oxygen?"

"How did he discover this method?"

"Ah, there are three ways to prepare oxygen!"

"No one has discovered it for so many years, but he discovered it. There is only: 2Na2O2+ in the chemistry textbook. But Li Zhen discovered it. Adding the two together, the answer is also equal to +O2."

"So careful."

“…”

Immediately afterwards, the physics teacher couldn't wait to raise his doubts.

Li Zhen took the trouble to give the answer again, and it was verified that it was so.

In the entire auditorium, there are leaders from the school, teachers from the middle, and students from the bottom. Everyone was shocked.

They just guessed that Li Zhen might be a top student, but today they discovered that Li Zhen had subverted everyone's perception without knowing it.

This knowledge... where did he learn it from?

In the ten thousand years of the new calendar, he knows all about concepts that have never been proposed in the history of the world.

Unanimously, all the teachers and students felt chills in their hearts, looked at Li Zhen, and only thought of one word to describe it-wisdom is close to demon.
