Twenty-eight years old, still gentle and pleasant?
Yang Dong's eyes couldn't help but light up. Just as he was about to speak, he suddenly thought of his identity, and a look of embarrassment appeared on his face.
"Ahem, I was pressed for time just now, so I forgot to introduce myself to you seniors."
"Seniors, my name is Yang Dong, and I am the general manager. I have gained some reputation in the capital recently."
Yang Dong? Ouchi manager?
These masters of arithmetic were startled at first, and then showed horrifying expressions on their faces.
Although they said they couldn't get out of the front door or step out the second door, they still heard about the affairs of the Great Zhou Shixian.
"Are you the Great Zhou Shixian?"
The famous arithmetic master surnamed Liu was shocked and subconsciously looked at Yang Dong in front of the blackboard.
Yang Dong smiled faintly, with a reserved attitude on his face.
"I've made the seniors laugh, but they are just some good people who make random nicknames and cannot be true."
Luo Suanzi nodded slightly, then thought of something and asked quickly.
"So...you are actually from the palace?"
Yang Dong nodded slightly,
"good."
As soon as these words came out, the arithmetic masters present couldn't help but sigh deeply.
What a pity, he is a eunuch!
If not, they would really have to fight for it. But since the other party is a eunuch, this matter is of no importance.
Several arithmetic masters laughed and settled the matter.
Luo Suanzi, on the other hand, still said seriously:
"Little friend Yang, my little girl loves arithmetic very much. If there is a chance in the future, please give me more advice."
Will it be... bad in the future? 33
After all, we are not that familiar...
Yang Dong cursed in his heart, but on the surface he smiled and nodded.
"It's natural!"
Luo Suanzi nodded slightly, accepting the matter. Immediately, he pointed to the quadratic equation question on the paper and asked:
"Little friend Yang, how should we analyze this question?"
Hearing this, Yang Dong picked up the talc pen again and started writing and drawing on the blackboard.
"Seniors, please see, this is the way Fanbang counts. What these represent is from one to ten. If you want to express hundreds and thousands, you need..."
"And these symbols represent addition, subtraction, multiplication and division..."
"By the way, there are also these letters. You can just think of them as Fanbang characters. We use these Fanbang characters to represent A, B, C, and D. They represent unknown numbers..."
"What? You asked me what unknown numbers are? Let's put it this way, we set one of the answers to unknown number A and unknown number B, and then..."
As the talc pen slides across the blackboard, these mathematical knowledge spanning countless centuries once again appear before people's eyes.
And there are a number of arithmetic masters, including Luo Suanzi, who is on the arithmetic ceiling.
At this moment, he was like the most devout student, silently absorbing the mathematical knowledge taught by Yang Dong.
If Yang Dong's method of seeking peace at the beginning was just a trick in their eyes. The unknown numbers introduced now, as well as the new counting system, seem to have opened a new door for them.
These foreign numbers are not only simpler, but also very convenient to calculate.
Coupled with this is Yang Dong's method of assuming unknown variables. Suddenly, the problem that was originally difficult to get around was solved.
Clear and logical.
After just a simple attempt, these arithmetic masters all praised it.
At this moment, they couldn't help but feel the same emotion as those great scholars.
This guy is definitely a genius!
It's just a pity that he is a eunuch...
After a detailed explanation, Yang Dong silently put down the talc pen in his hand. He knew that the effect of spreading his bait was slowly unfolding.
As for how many big fish can be caught in the end, it depends on the sky.
As the saying goes, it is up to people to plan things, and it is up to God to make things happen. This is the truth.
"Ahem, seniors, what do you think of this method?"
"Excellent, excellent! If we use this method to calculate arithmetic in the future, I think it will have the effect of getting twice the result with half the effort!"
"Not only that, I have a vague hunch that this calculation method will bring unprecedented changes to the entire arithmetic! Its value is even as much as the emergence of the abacus!"
"Little friend Yang, I have a merciless request. I know that the method you described is a secret of your sect. But this method is really of great benefit to arithmetic. I wonder if you can allow it. I'll wait. Teach these numbers and symbols?"
Looking at the serious arithmetic masters, Yang Dong nodded vigorously.
"This is natural! I brought this out today in the hope that the seniors can carry forward this method."
"In addition, this junior also has a merciless request..."
Upon hearing the unkind invitation, a look of vigilance flashed across the faces of the arithmetic masters present.
But soon they were relieved. After all, a junior has made such a big sacrifice. Let them pay some price, but it will make you feel more at ease.
Thinking of this, the arithmetic masters immediately nodded and said:
"If you need my help with anything, little friend Yang, just ask."
Yang Dong nodded slightly, with a reserved look on his face.
"Seniors, I'm planning to open an academy recently. I've already decided on a name. It's called Lanxiang Academy. It's just that there is no suitable teacher yet. I wonder if the seniors can..."
Hearing this, Luo Suanzi immediately shook his head.
He himself is too lazy to take care of his apprentices, so how can he have time to teach other students?
Wouldn't it be nice to get a little notebook and do the calculations yourself?
"Young friend Yang, I'm afraid this is inappropriate. Because I'm waiting..."
Yang Dong raised his hand and interrupted Luo Suanzi's speech. Then he gave an apologetic look and spoke first:
"Seniors, you don't know. At Lanxiang Academy, arithmetic can account for more than half of the study time."
"Is this true?"
Liu Mingjia's eyes flashed and he subconsciously asked.
"It's natural!"
Yang Dong nodded slightly and continued:
"Not only that, becoming a gentleman of Lanxiang Academy will also give you an allowance of one hundred taels of silver."
As soon as these words came out, another famous person's eyes flashed with light.
In fact, most of them who do arithmetic don't make much money. But relying on the reputation of the arithmetic master and the support of the family, he can survive comfortably.
But even so, hundreds of taels of silver a year still made him a little greedy.
After all, not everyone can be like the Hu family and the Luo family, with a big family and a big business, and no shortage of money.
"The allowance of one hundred taels of silver a year is pretty good. It's just..."
Before he finished speaking, Yang Dong glanced at the famous arithmetic expert and interrupted:
"This senior made a mistake. One hundred taels of silver is a monthly allowance. In addition, our academy also has quarterly awards, performance awards, year-end awards, etc..."
Some people died, but not completely...
