Tong Guò Yuan Chang's explanation of ancient Indian numerals, the four of them basically figured it out.

Guo Jia, as a think tank, understands the fastest, and often when Zhao Yun and the three of them are still thinking, Guo Jia already understands, and can draw inferences from one another. And the more he understands ancient Indian numerals, the more shocked Guo Jia is by the ancient Indian civilization that invented this number, thousands of years ago the country has already invented such a simple calculation symbol, if they are allowed to develop, how can the current Han Dynasty be able to confront it?

However, such a prosperous civilization could not withstand the footsteps of history and was annihilated in the dust of history.

"I don't want Yuan Gongzi to know so much, I admire it. ”

At this moment, Guo Jia was really amazed by Yuan Chang.

Prior to this, the world praised [Yuan's six sons] as all talented, and they were comparable to Yingchuan's [Xun's Eight Dragons]. At that time, Guo Jia scoffed, not to mention the other five members of the Yuan family, then Yuan Chang was simply a shame for the children of the Yuan family. However, it was only today that Guo Jia discovered that Yuan Chang's talent, at least in one aspect, was enough for one person to top the [Xun's Eight Dragons].

When the tiger was imprisoned, Yuan Chang told Guo Jia about his ambitions, but Guo Jia just felt that Yuan Chang was very scheming and used an incompetent appearance to cover up his ambitions. It was only today that he really understood Yuan Chang. No, perhaps, he just learned about Yuan Chang's ability.

"Hehe, I know that the lord is powerful. ”

"Humph!"

Yuan Chang snorted proudly, looked up at the ceiling, and showed a lonely and lonely expression: "Could it be that my son knows astronomy and geography, learns and is rich and has five cars, and people will tell you if they give him the nickname Bai Xiaosheng?

“…”

"Whether you believe it or not, I believe it!"

Although Dian Wei didn't know what Yuan Chang was talking about, it didn't prevent him from using what Yuan Chang said to express his admiration for Yuan Chang, and the purpose was self-evident.

"Damn, even I don't believe in myself, and you even say you do. ”

Yuan Chang stretched out his big foot and kicked Dian Wei away, ignoring Dian Wei's resentful eyes.

Dian Wei straightened up his messy clothes, and said flatteringly: "Lord, you see that I usually get dizzy when I see words, and I have already understood what my lord said today, is there any more difficult way to teach us?"

It is true that the ancient Indian number is not difficult, it is only ten numbers. When Yuan Chang crossed over, the children in the kindergarten could already count to a hundred, even if Dian Wei was full of muscles, after all, he was also an adult, and it was not difficult to understand. And Guo Jia, Zhao Yun and Han Sui, whose IQs are significantly higher than Dian Wei, are not a problem.

"So, I'll teach you addition and subtraction, multiplication and division is more difficult, and I'll teach you later. ”

Yuan Chang took out a ledger casually, and then wrote down the content on it with ancient Indian numerals, followed by a "+" sign, indicating that this is "addition".

"'Addition' is easy to understand, for example, if your salary is 300 stone this month, it will be 300 stone next month, and if you add the two, then it will be 600 stone. The same is true for 'subtraction', for example, if you have a salary of 300 stone this month, and you have used 100 orders for food, clothing, housing and transportation, then after offsetting, you will only have 200 stone left. It's better to say too much than to put it into practice, so each of you can take an account book and calculate it to see how well you learn. ”

After Yuan Chang finished speaking, he issued a task to the four of them, and he picked up a glass of wine with a smile on his face, and sat comfortably on the side and watched the four of them calculate.

"Wrong, wrong, three hundred and seventy-five sheaves of grass were taken to feed the horses, and two hundred and sixteen sheaves were fed, how could there be one hundred and sixty-one bales left?"

Yuan Chang took the time to glance at Dian Wei, and immediately scolded angrily. That look, it is even more teacher than the teacher before he crossed over, and Yuan Chang is also too addicted to teachers, and secretly thinks in his heart that in his previous life, those teachers had to scold students for being stupid at every turn, and he was in such a comfortable mood.

"Don't you know that five is less than six? In that case, five is not enough to subtract, so you have to borrow it from ten. That's right, after minusing, it's a hundred and fifty-nine bundles. ”

"So that's the case, the lord and I understand!"

Dian Wei was not frustrated when he was blamed by Yuan Chang, but was a little excited to feel that he understood, so he continued to calculate.

"Stupid, how can one hundred and twenty-six stones plus seventy-four stones be one hundred and ninety stones?"

However, Dian Wei, who was excited for a long time, was scolded by Yuan Chang again.

"Lord, where am I wrong?"

"One hundred and twenty stones plus seventy stones is one hundred and ninety stones, then let me ask you, where did the other six and four stones go? ”

Dian Wei scratched his head, and after calculating again, he found that he was really wrong, and he honestly accepted Yuan Chang's accusation.

"Bonghyo, you miscalculated one place..."

"Zilong, there are three places where you miscalculated..."

"Ju Zi, you are the same as Zilong..."

"As for Hong Fei, there are too many mistakes, I don't want to say it..."

"Alas!"

Yuan Chang shook his head, as if he was very dissatisfied. In fact, Yuan Chang is just pretending like this, don't say that Guo Jia and the four of them are just in contact, even if Yuan Chang studied for so many years in his previous life, there will always be mistakes. There are also those in high school and college who also make mistakes from time to time. Yuan Chang sighed like this, naturally thinking about teaching the four people a lesson.

Regarding Yuan Chang's accusation, the four of them lowered their heads in shame, feeling that they had failed Yuan Chang's teachings.

Such a simple thing, they would even miscalculate, not to mention Yuan Chang's accusations. When they feel guilty when they find out what they are wrong, how can they be wrong?

Of course, Guo Jia and the four of them didn't know the truth, otherwise they would have been speechless about Yuan Chang's strange behavior.

Yuan Chang shook his hand and comforted: "Forget it, although this thing is very simple, but after all, you are learning for the first time, and mistakes are inevitable, just pay attention next time." ”

Listening to Yuan Chang's words, Guo Jia's faces suddenly relaxed a lot.

Yuan Chang's heart is even more dark, no wonder in his previous life, many students will not hate the teacher when they are scolded by the teacher, but they are grateful in their hearts, and feel that the teacher is really good to them. And some students are deliberately naughty, and after being scolded by the teacher and comforted again, they are much more honest, and their feelings are like this.

Looking at the expressions of Guo Jia and the four of them at this time, don't they have the same mentality as those students?

Thinking of this, Yuan Chang felt that he could also get a school in the future, and then stood in front of thousands of students to point out the country, scolding Fang Xuan, and it was really cool to have a good time.

It is precisely for this reason that Yuan Chang had the idea of founding a school in the future. But many people don't know that the reason why Yuan Chang founded the school is because of such an idea. If you let the world know Yuan Chang's reason, it is estimated that you will be shocked!
