The correct way to open the sprite

Chapter 47 Teacher Feng's Math Class
What made Feng Yu more troublesome was that there was no cheap pen and paper. Feng Yu could only think of a crooked trick. He used a porcelain kiln to burn a batch of porcelain plates one meter long and half a meter wide. The surface of these unglazed porcelain plates Slightly rough, he painted small blackboards with charcoal.

While he was scribbling, he complained about the elves. After so many years of messing around, he was so poor that he was so stupid. After the opening of China, 2000 years later, there were prosperous dynasties one after another.

It seems that the living environment of creatures really can't be too good. Because the living conditions are too good, the black uncles lie under the trees all day long waiting for the fruit to hit their heads, drying birds for fun, and they haven't made a name for themselves until now.

The elves are even more so. The history of civilization far beyond ten thousand years has been mixed up, and it has become such an embarrassing situation.

As a native of another continent, Feng Yu has a close relationship with Nicole, and his lectures have caused quite a stir in a small area.

Anthony only found thirteen students from the students he promised, but there were quite a lot of people watching in his first class. Even Nicole didn't meditate, and stood beside Anthony, waiting for Feng Yu to give a lecture.

Not only Alan and Dick came, but Feng Yu also found the elven magister who had been thinking about alchemy as his deputy on the spot, which made his enthusiasm for lectures even higher.

Time to show off a wave of real technology.

Originally, he planned to give the students Arabic numerals as the basis for the first class today, but after seeing so many spectators, he knew that he had to come up with something to shock them today, so as to pave the way for his next actions. a basis.

At the very least, I have to level the IQ gap with these self-righteous people, so that they don't put themselves too high one by one, and look at Feng Yu like a visitor from a wild world.

After listening to Nicole's magic class twice, Feng Yu didn't go again. He found that the way the magicians in the camp looked at him changed. This made Feng Yu very upset.

Those who study magic don’t know the nature of elements, those who study alchemy don’t know the laws of chemistry, and those who study herbal medicine don’t even know plants. Who the hell gave you the courage to follow the time traveler? Tilt tail? !
Feng Yu himself burned a large two-meter-long blackboard, and his kiln is only that big.

He glanced at the crowd around him, and wrote a set of elf characters on the blackboard with long strips of limestone: Mathematics.

Feng Yu clapped his hands, and the onlookers slowly fell silent.

"If you have any questions about what I'm talking about, please raise your right hand to indicate that you can only ask questions with my permission. This is a respect for the teacher and a manifestation of personal cultivation."

After Feng Yu finished speaking, the low-pitched communication on the scene stopped.He glanced at Nicole, who was holding Anthony's arm, and stood by the blackboard to start the first scientific enlightenment class for human beings in the high magic world.

"Griann Continent and my hometown are very different in terms of culture. The biggest difference lies in the focus. I once watched the collection of books in the tent of the Great Magister Anthony, and I have to say that the literature of Grian Continent The development is excellent, and I have seen quite a few works of literature that can be called great.

These great writers were impassioned and wrote one after another that can be called immortal works.

So today I will not talk about literature, but talk about something we study, which is the two words I wrote-mathematics.

Maybe the students will ask, what is there to say about mathematics, who doesn’t know mathematics, no matter how stupid a person is, eating three meals a day will never make a mistake, right? ! "

Several elf teenagers couldn't hold back and laughed in front of the great magister Anthony, including Nicole, but they quickly stopped laughing.

"That's right, who doesn't know mathematics?! But ask this question in reverse, who doesn't know literature? We can't write immortal poems. It's not difficult to record what we say and do every day. Bar?!
Some people will say, that is not called literature.

I also want to say that counting how many meals you have eaten every day and how many bowls you have eaten for each meal is not math, it is the same as recording what you have said every day.

There are immortal poems in literature, but what does mathematics have?

Everyone knows that I brought the way of making salt in my hometown to our camp. Chief Alan and Chief Dick are working hard to build more sun-dried salt fields, so that every family in the camp will no longer suffer from the difficulty of eating salt. effort. "

Alan and Dick stood in the crowd, proudly raising their heads.

Feng Yu continued: "I told Patriarch Dick to build the salt pan according to the size I designated, so that everyone in the elves, dwarves, and halflings can eat salt.

So, how did I figure it out? "

Feng Yu wrote a series of numbers on the blackboard, and then said: "The amount of salt each of us eats each year is limited and stable, which lays a foundation for calculation.

Then, based on the total population of the three tribes, we know the total amount of salt that all the three tribes need each year, and the same is true for the output of each salt field.

In this way, we can calculate how large a salt pan is needed to meet the salt needs of all the population of the three ethnic groups. "

Feng Yu filled the blackboard with symbols, and finally came up with a number, then tapped the number with his hand, and said back: "After calculation, it only takes about five miles of Yantian to do it."

The onlookers were all prominent figures in the camp. When they heard this number, they were not calm, and there were discussions everywhere.

Anthony patted Nicole's hand calmly, Nicole glanced at her grandfather, and raised her little hand in a pretty way.

Feng Yu glanced at her and said, "Nicole, do you have any questions?"

"Darren, how did you come up with that number?"

"I calculated it through numbers. It's very simple, but it needs some data support. For example, each person needs about 5 catties of salt consumption per year, and the amount of salt that can be produced per mu of salt field per year. As long as you know these, this number It can be easily calculated.

If you still don’t understand anything, welcome to continue to listen to my class. In future courses, I will gradually teach you more advanced ways of using mathematics.

In order to let everyone better understand the magic of mathematics, I am going to play a small game with you now, no matter you are a student or you can participate.

Everyone knows the rice bar that the halfling brothers use to make flour. The food made from the rice stick noodles is delicious, thanks to the great halfling brothers. "

Feng Yu patted his left shoulder, saluted Allen, and then continued:

"My little game looks like this:

If I take out three hundred catties of salt to exchange sticks of rice with you, you only need to pay me one stick of rice for ten catties of salt for the first time, two sticks of rice for ten catties of salt for the second time, and ten for the third time. Four catties of salt, eight ten catties of salt for the fourth time, sixteen ten catties of salt for the fifth time. "
