During the pre-Qin period, everyone basically relied on counting sticks.
The largest number was only 30,000.
Ying Zheng couldn't figure out how the result of over ten thousand was calculated.
"Master, is this also scientific?”
Forget it, forget it.
Just treat it as tutoring for primary school students.
Sun Huan took out a piece of paper, picked up a pen, and wrote down a mathematical formula on it.
He had just finished writing the numbers.
Ying Zheng was puzzled again.
What was this?
These symbols were extremely simple and clear, and their arrangement was very strange.
" This is Arabia…This is a number. This is one, and the corresponding ones are two, three, four, five…"
During the pre-Qin period, Arabic numbers had not yet been introduced into the Celestial Dynasty.
Everyone was still using capital letters 1, 2, 3, 4, 5.
It was not as simple and convenient as Arabic numbers.
The mother and son nodded.
"Looking at it this way, it's indeed much easier to remember and it's very easy to write.”
Sun Huan listed the formulas and then multiplied them using the decimal system.
He wrote the answer on the paper.
"Have you learned it?"
Suddenly, Ying Zheng's eyes shone with a strange light.
Borrowing position to enter one!
In addition to the Four Arithmetic Rules and Nine Jiuge.
He could actually calculate the result so quickly.
It was not difficult for Ying Zheng to tell.
The wonderful use of numbers was in expansion.
In the future, no matter how big the number was, it would be fine. He could just use a formula and calculate it.
Turn complexity into simplicity.
"I've learned it! Master, you taught me such a divine skill just like that. I really don't know how to repay you.”
Sun Huan rolled his eyes at him.
It was something that could be calculated by any elementary school student.
He was even grateful for this?
"This is nothing. I'll teach you more complicated things another day. This isn't even elementary mathematics. I still have advanced mathematics for this beginner mathematics.”
Zhao Ji was still calculating at the side.
He had been looking at Sun Huan.
I forgot to listen carefully!
Later at night, he would ask Ying Zheng how he had calculated it.
Sun Huan had nothing better to do and was just casually saying.
Ying Zheng's eyes were filled with admiration.
"Master, is there advanced chemistry in chemistry?”
Sun Huan nodded.
Mathematics, Chemistry, Physics, Biology…
They were all good things that benefited mankind.
If it wasn't for the fact that his disciple was an iron fool, it didn't matter if he taught him.
Thinking of this, Sun Huan became even more depressed.
Sigh!
He had a body full of knowledge, but he couldn't find anyone to inherit his legacy!
Ying Zheng carefully put away Sun Huan's divination paper.
He could already tell.
The counting method that Master used just now was a real immortal technique.
This was another divine item that was enough to become a saint on the spot.
However, Ying Zheng had been by Sun Huan's side for a long time.
It also changed some of his noisy personality.
He was no longer surprised by such a divine item.
"Mother, Master invented mathematics. You have to remember it well!”
"Yes, I remember. You still have a lot to learn from City Lord Sun.”
Ying Zheng looked at Sun Huan with a burning gaze.
"Master, when can I learn advanced mathematics?”
"For someone like you, a stupid bird has to fly first.”Sun Huan said sadly," Zhao Chu, you have to believe in yourself. You're just a little dumber than others. Don't be sad.”
Ying Zheng was instantly dumbfounded.
What right do you have to call me stupid?
Could there be someone smarter than him in this world?
Ying Zheng was furious.
"Master, I'm not stupid. If you don't believe me, test me!”
"Then I'll test you on the simplest one.”
"There is a cage with chickens and rabbits. From the top, there are thirty-five heads, and from the bottom, there are ninety-four legs. Go back and count how many chickens and rabbits there are.”
Ying Zheng was stunned.
Zhao Ji was also stunned.
The mother and son immediately took out a piece of paper and began to calculate.
Two days later.
Both mother and son had become giant pandas.
This question.
No solution!
Ying Zheng's mind was filled with thoughts of chickens and rabbits, and he had almost lost all his hair.
Zhao Ji was even confused about what a rabbit and a chicken looked like.
The two of them looked up at the sky and cried.
These two days, Sun Huan had not been idle either.
The Dragon Boat Festival was approaching.
Sun Huan was busy distributing benefits to the residents in the city.
He found five cows.
These were all beef cattle raised by Sun Cheng, not for farming.
Then, he stewed beef bone soup in dozens of large pots with beef bones and sprinkled some seasonings.
The remaining beef was just enough to make the sliced beef rolls.
He planned to set it up on Sun Cheng's big square on the day of the Dragon Boat Festival and invite everyone to eat hotpot.
"Zhao Fang? Where have you been for so many days!"
"Come over and help. Go and see if the wood is ready. Why hasn't it been transported up yet?”
Only then did Zhao Ji push open the door and walk out in a panic.
His face was haggard.
When Sun Huan saw her like this, he was also a little puzzled.
"What's wrong with you? Did you not sleep well again?"
Coincidentally, Ying Zheng's roar could be heard from the room.
"I can't calculate it!"
"I'm so useless!"
"Am I really not smart enough to understand the essence of Master's mathematics?!”
Sun Huan was speechless.
It seems that you have been calculating for two days and two nights, but you still haven't figured it out!
How stupid.
The problem of chickens and rabbits being in the same cage could be solved in the future, even without using a linear equation.
"Don't count. 12 chickens and 23 rabbits!”
"Come out and work!"
Upon hearing the correct answer, Ying Zheng's expression immediately turned into ecstasy.
After searching through the pile of papers for a long time, he picked up one and ran out of the room.
"Haha! So that's how it is!"
"As expected!"
"Why didn't I think of this? This is the correct answer!”
Crazy!
This was crazy!
This disciple of his was getting crazier and crazier.
Sun Huan waved his hand. He was busy at the moment and didn't have time to pay attention to him.
Fortunately, Zhao Ji was an adult after all.
After knowing the answer, he didn't act too shocking and immediately ran to the forest farm according to Sun Huan's instructions.
After running for a while with his feet closed, Ying Zheng finally calmed down.
He happened to see the bustling scene in the big square.
In the square, dozens of large pots were boiling soup.
The air was filled with the fragrance of meat.
"Cough cough! Master, what are you doing?"
"It's almost the festival. I'll let you guys eat beef hotpot to celebrate.”
Beef hotpot!
Pure meat!
Sun Huan thought of the pleasure of eating meat and drinking wine.
They could not help but swallow their saliva.
Usually, he could not bear to do this.
However, it was a holiday.
As long as everyone was happy.
Ying Zheng swallowed his saliva as he smelled the meat.
Beef?
In ancient times, cows were used to plow the land.
a bull can be compared to a man, but precious in gold.
Even if he was injured, he would have to report it to the authorities, let alone eat it.
The family that raised the cattle would be punished.
Ying Zheng was the current Crown Prince.
He had eaten beef before.
The taste was still fresh in his memory. It was delicious!
Ying Zheng did not know what hotpot was.
However, when he saw how happy everyone in Sun Cheng was, it was definitely a rare delicacy.
