Chapter 808: On the importance of talent and mathematics (3 in 1)

After Wu spoke, most of the people around him agreed with what Wu said, especially the second senior brother who had just wrestled the hammer for a while.
Now in the entire tribe, he has the greatest strength in terms of strength alone, and just now he personally turned the hammer and smashed it for a while, his arms were numb, and he did not squeeze out a few drops of oil. Come, we can see that there is really no oil in it.
Moreover, so much oil has already been squeezed out of it, and there is a full pot, and it must have been squeezed out of the oil.
Han Cheng scanned the surroundings and saw that most of the people around him agreed with the view of witches. Those who did not snorted, from the demeanor, it can be seen that they very much agree with the view of witches, only Yuan did not say anything, some hesitating Look like.
"Yuan, do you think there is still oil in it?"
After seeing Yuan's expression, Han Cheng asked in a voice.
During this period of time, Han Cheng has successively taught a lot of mathematics about Yuan. Simple addition, subtraction, multiplication and division can already be mastered. At this time, the look of Yuan seems to have been discovered.
"There should be oil in it."
After hearing Han Cheng's roll call, Yuan hesitated and said aloud.
Han Cheng ignored the disbelief and surprise of Wu and the others, but smiled and asked Yuan again: "How do you judge that there is oil in it?"
Asking this way, I am expecting.
"Just..."
Yuan said that there was a pause. After opening her mouth a few times, she didn't think about how to express what she wanted to say. After scratching her head for a while, she suddenly squatted on the ground and found a wooden stick. , Began to write and draw on the ground.
The witches, the second brothers, and others who watched this scene were puzzled. Didn’t the son ask how he knew that the oil was not squeezed clean? Why do you squat on the ground and start writing now?
Can you write?
When Han Cheng saw such a scene, the smile on his face grew thicker.
He leaned over to watch Yuan write and paint on the ground with branches.
The first to be written on the ground by the circle is the nine-nine multiplication table.
The nine-nine multiplication table is in the order taught by Han Cheng, and the circle can be written silently, but it has not yet reached the point of proficient use.
Therefore, when calculating, the circle needs to write the multiplication table silently, and then look at the multiplication table to perform multiplication and division operations.
After writing out the multiplication table, she began to draw the division symbols on the ground with branches, and then divided by thirty-five to five, and compared the nine-nine multiplication table to the result of seven.
Then divide three hundred and fifty to five, and after some calculations, seventy is obtained.
The result of this calculation is correct, but it cannot solve the current problem.
Han Cheng could see the problem at a glance, but he didn't mention anything. Instead, he stood there and watched the circle that continued to be calculated there like a primary or second grade pupil.
After some calculations, Yuan wrote out the last subtraction operation. With the help of counting fingers, after another calculation, he subtracted thirty-five from seventy and got a thirty-five.
"God, there is still so much oil in it that has not been squeezed out."
Yuan pointed to the bottles containing tung oil and said aloud.
Before performing calculations, Yuan vaguely felt that the oil inside had not been squeezed out. Later, after hearing Shenzi's question like that, this idea became more convinced.
However, she was not proficient in adding, subtracting, multiplying and dividing these things, and she couldn't tell the problem in one mouthful, so she just squatted on the ground for a long time.
Brother Wu and Brother Er looked at the two oil jars in the direction of their round fingers, and their faces showed disbelief.
They could all see it very clearly. This time, a large pot of oil was squeezed out, which was as much as 35 catties, and it was contained in these two jars.
And the second brother who had the strongest strength just now took a bronze hammer and smashed it hard. As a result, a few drops of oil did not come out. Under such circumstances, Yuan actually said that there was 35 oil in this simple oil press. If they didn't squeeze it out, they certainly didn't believe it.
How can this be? !
"God, really has so much oil not been squeezed out?"
Wu said, scratching his sparse hair, with a wave of puzzlement.
He didn't believe it at first, but seeing Yuan would say that there was oil in it, Wu also became a little unsure.
After living together for nearly a year, as Wu learns more about Yuan, he knows that Yuan is a very smart woman.
What she said at this time, although it didn't sound like true at all, Wu still murmured in his heart.
Especially when Yuan was squatting there just now, holding a branch on the ground, writing, counting, and counting his fingers, and still muttering words in his mouth, it looked very like something, very bluffing.
When Wu asked, the rest of the people, including Yuan who was a little worried, all looked at Han Cheng in unison.
Han Cheng smiled and shook his head: "There is not so much oil."
As soon as the words came out, Wu and the second brothers breathed a sigh of relief, especially the second brother, they even cracked their mouths, and just said, just now they shook his arms to numb, and they had to use strength It's over, how could there be so much oil not being squeezed out in such a situation?
There was a look of entanglement and doubt on Yuan's face. According to the calculation method given to her by Professor Shenzi, there was still 35 kilograms of oil that had not been squeezed out. What did the Shenzi say now?
"It's not as much as the thirty-five catties that Yuan said, but it's also a lot."
Not waiting for how long the two brothers were happy, Han Chengcheng once again attacked everyone. After saying this, he smiled and said to Yuan: "You count it."
The circle, which was originally full of entanglements and doubts, was said by Han Cheng without too much nonsense. She squatted directly on the ground and began to carefully check the calculation process she had just written on the ground.
In the process of careful inspection, Yuan would write and draw with the branch in his hand from time to time, with a thoughtful look in his eyes.
After maintaining this state for a while, Yuan's eyes suddenly lit up, and after a short pause, he took a branch as a pen and began to calculate in another place.
Different from the slow swallowing during the inspection just now, the round stroke is much faster this time, and the whole calculation process looks much smoother.
"God, it's fifteen catties, not thirty-five catties!"
After performing this calculation for a while, Yuan, who was squatting on the ground, raised his face suddenly and said with surprise when he looked at Han Cheng.
Han Cheng looked at her approvingly, nodded vigorously at her, smiled and said, "Yes, it's fifteen catties!"
While saying these words, Han Cheng also gave Yuan a thumbs up.
The female priests of Yuan, a former semi-agricultural tribe, are indeed smarter than ordinary people. There have always been professors in the tribe for such things as mathematics. Most people in the tribe can do addition and subtraction. Suddenly he was caught blind.
The rest of the people who can perform multiplication and division operations, and a large part of them, simply allow them to calculate the numbers on paper, but they cannot apply it to daily life to solve practical problems.
But Yuan, a female priest who was once a semi-agricultural tribe, has not been exposed to mathematics for a long time compared to most people in the tribe. It took more than two months. As a result, it has been able to apply it to solving practical problems. .
In addition to adding, subtracting, multiplying, and dividing today's series of calculations, there are actually some proportional issues involved.
Although Yuan didn't quite understand this, he independently worked out the correct result.
Although the calculation was wrong the first time, it is already very rare.
After all, she has not been exposed to mathematics for a long time, and the actual application is much more difficult than simply calculating numbers.
Sure enough, mathematics is a subject suitable for smart people, and in many cases talent is really important.
The people in the tribe worked hard. The vast majority of people are good hands and are not embarrassed at all. However, when all kinds of knowledge are involved, many people lose their legs and feet.
The Chinese characters are all better. After all, attracted by these popular Qingque tribes such as "Little Tadpoles Finding Mother" and "Monkeys Finding the Moon", everyone is still very interested in these learning.
But mathematics that is more abstract and needs to remember many rules is really painful. Even the best stone in the tribe, when it comes to mathematics, you still scratch your head. It's just a simple four arithmetic calculations, and if you go deeper, you can't understand or learn.
In this whole tribe, the level of stone is top-notch.
Now that he discovered Yuan, a good seed, Han Cheng couldn't let it go, and he needed some encouragement.
This will help Yuan better immerse himself in the fascinating world of mathematics, and go further and further, laying the foundation for the future development of the tribe.
Han Cheng, who came from later generations, naturally knows the importance of mathematics, especially after society has developed to a certain level, Han Cheng understands the role that higher-level mathematics can play in the development of society.
Sophisticated and complex mathematics knowledge is of course not needed when buying vegetables, but there are many things in this world besides buying vegetables.
When studying mathematics, Han Cheng was really embarrassed to lose his hair, but after working, he used very little, but he would not deny the meaning of learning mathematics.
Now that Han Cheng has come to this world, he will naturally not abandon him.
People who were hit on the head by an apple said it was easier to pick an apple while standing on the shoulder of a giant.
Compared with the current tribe, Han Cheng is undoubtedly a giant. If he can leave all these things behind, then future generations, based on the foundations he has laid, can stand by others at birth. It is likely to be above the end that will never be reached in his lifetime.
Using this as a starting point, one can always go further and make the tribe better.
Of course, these are things that have been many years from now.
However, leaving these future things aside, the Qingque tribe at this time also needs mathematical knowledge.
For example, statistics on the harvested grain and the fur in exchange.
Calculated by head, how much food does the Qingque tribe need in a year to eat? How long will it take for a road to be built by different numbers of people?
The crops in the ground can be harvested in about a few days if everyone works together...
This series of things all need to rely on mathematics to calculate in order to be aware of.
Although there will be errors, they are much more accurate than estimated.
Not to mention the rest. If Han Cheng didn't know the oil yield difference by calculation, the oil contained in the oil residue would be wasted.
After hearing Yuan say fifteen kilograms and getting confirmation from Han Cheng himself, the Second Senior Brother and the others were a little confused.
Although 15 jin is not as much as 35 jin as Yuan said before, it is also not a small amount.
You know, this time only 35 kilograms of oil was squeezed out, and two cans were filled.
This 15 kilograms of oil can basically fill a jar!
"God... Son of God, really has so much oil?"
The second senior stammered at Han Cheng and asked.
Han Cheng nodded and confirmed the matter again.
Seeing this, the second senior, who was scratching his hair, was holding a bronze hammer and was about to smash these wooden stakes again, but was stopped by Han Cheng.
After this consideration, Han Cheng has roughly wanted to understand why the oil output rate this time is so different from the last time.
This time, I put in more tung oil fruit powder, which was ten times as much as the last time.
When such a large amount of tung oil fruit powder is piled together, the elasticity will increase and it is not easy to smash it through.
To sum it up in one sentence is to be more greedy than to chew.
The second senior who was stopped by Han Cheng was there scratching his hair, and he was scratching his hair with him, Wu, who had just calculated that there were 15 kilograms of oil in it, and more people.
The second brother’s strength is the greatest among all the people in the tribe. This is recognized by everyone. Now the son of God stopped the second brother and didn’t let the second brother use the hammer. How can I get the remaining oil?
Of course there is a reason why Han Cheng stopped the second brother. The second brother's power was no longer able to squeeze out the remaining oil. If it could be squeezed out, it would have been successful before.
This would be a waste of effort even if he held the hammer again for a while.
"God, what should I do now?"
The crowd looked at Han Cheng with incomprehensible colors in their eyes. Even the most powerful second senior brother could not help the remaining tung oil. They really had no way to think about it.
"I have a way to squeeze them out!"
Man’s abilities are limited. You can’t swim with fish, you can’t run to catch up with horses, and you can’t fly in the air like a bird.
However, because people have developed brains, they can create various tools to solve various problems they face.
With the help of ingenuity, with the help of various tools, you can go to the sky and dive into the deep sea...
When the strength of the body itself reaches the upper limit, then tools are needed.
Han Cheng made a simple tool this time. It was a hammer, similar to the one used to strike bells in the temple.
However, the section of wood used for the impact wood is larger, longer, and heavier than that of the ordinary temple, and the impact force is correspondingly greater.
"Boom!"
"Boom!"
Han Cheng used his hand to tie the rope on the ram, and after pulling the ram to the rear, he pushed it back with the force of the ram.
The hammer with great power, under the control of Han Cheng, with its own weight and the inertia of swinging in the air, plus the power that Han Cheng added to it, a fellow slammed into the wood. Above the pile.
There was a circle of strange-looking people all around.
Everyone chooses to believe in this kind of tool made by the son of God, but there are some people who can't believe it in this kind of belief.
Because the second elder brother with the strongest strength in the tribe couldn't smash it with a bronze hammer, the son, who is not known for his strength, said that he would use such a tool to knock down the stake and then squeeze the oil.
Even though they are sincerely convinced by the Son of God, under such circumstances, there is still some unbelief in the belief.
However, when the ram made of rough wood hits the stake under Han Cheng's control, the onlookers who were watching widened their eyes. Those in their hearts did not believe that under the impact , All turned into powder, transformed into surprise and disbelief!
Under this collision, the second senior brother with the strongest strength in the tribe could not smash the wooden stake with a bronze hammer, but was smashed in with a progress visible to the naked eye.
"Oil! Oil! Oil is coming out again!"
When many people were still surprised by such a scene and did not come back to their senses, someone pointed to the bottom of the simple oil press and shouted excitedly.
When everyone heard the words, they looked at the simple oil press that had been determined to have no oil. After Han Cheng pulled the ram and hit it again and again, the oil began to drip, and it quickly disappeared from one drop. The drops became several thin lines...
It turns out that there really is so much oil in it. It turns out that hanging a piece of wood horizontally has such a big impact!
"Come on, bump with me!"
After Han Cheng pulled the ram by himself for a while, he said to the second senior who was standing aside.
At the sign of Han Cheng, the second brother stood on the other side of the hammer, and then worked hard with Han Cheng on the left and right, pulling the hammer back and raising it, and then pushing it forward.
With the participation of the second senior brother, a powerful person, the advantage of the hammer has been fully utilized.
With the impact of the hammer again and again, the stakes were smashed in little by little, and more and more tung oil was squeezed out of it.
"God, this method is really good!"
Seeing that after the weighing, the tung oil reached more than seventeen kilograms, the second brother said excitedly.
Using this method, not only can the tung oil be squeezed clean, but also very labor-saving.
Even though the second brother’s strength is great, when he can save his energy, he doesn’t want to exert too much effort. He is as tired as a lucky general who stretches out his tongue to radiate heat...
Because of the successful manufacture of the oil press and Han Cheng's production of such a labor-saving and efficient hammer, the Qingque tribe seemed very happy.
Those lively and active minors, always like to get here when they are okay, and always want to come and play with the hammer when they take the time.
Han Cheng was also very happy. On the one hand, he took the people from the Qingque tribe and got the oil press out of nothing. From now on, another kind of machine has been added to the tribe. That is, Yuan is really talented in mathematics as he had imagined.
This is the benefit of smart people. In many things that require brainstorming, progress is always fast.
After the successful large-scale oil extraction this time, Han Cheng did not ask anyone to continue to press the oil. Now the oil extracted is enough, and the remaining tung oil fruit can be extracted in winter. After all, at that time , The people in the tribe are more leisurely.
After such a busy schedule, the autumn mood was even more left, and the grass around the tribe turned dark green. When I got up in the morning, with chilly dew stuck to the grass leaves, it looked white.
When people walked by, the dewdrops rolled off between the swaying grass blades, sticking to the feet, some frozen feet.
The mountains and forests in the distance have also become colorful, although it has not reached the point where the mountains are red and the forests are all over, but it is already fast.
Unconsciously, the late autumn of Qingque's ten years has arrived.
In the courtyard, Han Cheng wearing leather gloves directly dipped a pair of vine armor into a pot of tung oil. After turning it back and forth a few times, the entire vine armor was covered with tung oil.
Holding the rattan armour in his hand and waiting for a while on the top of the pot~EbookFREE.me~ When no oil dripped down on it, Han Chengcheng took this rattan armour and hung it on a shelf not far away. on.
Ten pairs of vine armours soaked in tung oil have been hung on this shelf. At this moment, under the sunlight of late autumn, it carries some light and looks very beautiful.
"Boom boom boom, boom boom boom..."
Little Pea, who was carried by the pandas around the tribe, held a rattle in his hand, shaking it back and forth, grinning silly, happily like a second fool.
The rattle in Little Pea's hand also seemed to have a layer of light, which was much more glamorous compared with the dim color before.
This is also the reason for saving several layers of tung oil.
However, the rattle was not thrown into the tung oil basin, but was rubbed with the unsuccessful silk woven by Bai Xuemei with the tung oil, so that it is not easy to leave any traces on it, and it looks more beautiful.
"Tuk tu tu..."
This is the sound of the crutch point on the stone road.
As the sound approached, the witch with a cane in one hand and a handful of wild fruits in the other appeared in his vision.
It's just that Wu's walking posture at this time seemed very awkward. Every time he walked forward, his body would involuntarily lean toward the side of the crutches, and the crutches extended in a large range and high frequency.
It didn't look like he was walking, but he was showing off his crutches.
In fact, Han Cheng had let Lie and Wu do it a long time ago, but Wu felt that holding the cane would make him look old and could not highlight the strength of his bones, so he left it there and never used it.
However, since Han Cheng soaked the crutch in mint juice for several days, dried it, and wiped it with unsuccessful silk cloth dipped in tung oil for several times, Wu couldn’t walk without this crutch. Take it everywhere...
