learned from Hao Youqian's mouth: When he was very young, Hao Youcai saw that he was very talented, so he squeezed his time hard and let him learn arithmetic.

Can't figure it out, beat the handboard, don't give food, sleep in the horse pen, sweep the toilet, clean the manure pit......

As long as it was a punishment that could be imagined, Hao Youqian had experienced it all.

Recalling that dark learning experience, his tears almost fell.

The dead old man in his house is so hateful!

"Let me learn arithmetic, it's better to stab me to death with a sword!"

Puffing up his chest, Hao Youqian showed a posture of "generous to death".

"I, Hao Youqian, even if I die, I will not touch arithmetic again if I jump from the second floor of Xuefeng Building!"

"But ......"

"Nothing good!"

"Didn't you want to be a scientist before? If you don't study arithmetic well, you can't become a scientist. ”

Hearing Su Yin mention the matter of engaging in scientific construction, Hao Youqian's heart kept beating again.

When Su Yin talked to him about bacteria, he was deeply attracted by those magical things.

In the face of unknown things, people are always full of curiosity, and Hao Youqian is no exception.

After being silent for a long time, he said suspiciously: "You won't lie to me, will you?" ”

"What am I lying to you for? Can it be eaten as a meal? ”

"Let me think about it."

"Okay."

A few minutes later, Hao Youqian picked up the teacup and saluted Su Yin, "Mr. is above, please accept the student's bow!" ”

It's so fragrant.

"I don't take protégés."

"Brother Su Yintai, you can be accommodating. I really want to be a scientist...... Ahh ”

"Again, I don't accept protégés. But...... It's still no problem to teach you arithmetic. ”

"If you don't apprentice, you can still learn things from you, Brother Su Yin, you are so good!"

"How do I feel like you're mocking me? Don't you know what kind of person I am? ”

As he spoke, Su Yin casually wrote a topic about chickens and rabbits in the same cage.

Throwing the question to Hao Youqian, she dismissed: "Let's try to solve this problem first." ”

"Solve the problem?"

"yes. Mathematics is nothing more than a set of formulas, column equations, and solving functions. ”

During the time when Hao Youqian was doing the topic, Su Yin found the people in the village.

Her eyes swept back and forth in the crowd several times, but she still didn't see Meng Minghan's figure.

Just as she was about to ask where the four masters were going, Meng Minghan broke in through the window.

With a bitter face, Su Yin said solemnly: "Fourth uncle, can't you go to the main gate when you come back?" It costs money to repair windows! ”

"Don't worry, your fourth uncle and I are very neat with our hands and feet, and we won't break the window."

After blowing about how cautious he was in acting, Meng Minghan reported to Su Yin what he had found in Jinqiong's Mansion City.

The result was similar to Su Yin's expectations.

When the store first opened, there were many people who were eyeing Xuefeng Lou.

After Hao Youqian released the smoke bomb that wanted to seize the perfume industry, those people withdrew as soon as possible.

There is no rush to make a move, what we need to do now is to figure out Hao Youqian's intentions.

Did he mean those words, or did the Hao family mean them?

If it's the former, they don't mind a piece of the pie; But if it's the latter, this piece of fat will be difficult to gnaw, and it will take a long-term view......

"Fourth uncle, please leave it to you during this time."

"It's okay, the big boss will brew a few more jars of wine for me."

After dismissing everyone, Su Yin returned to the second floor and checked Hao Youqian's situation.

I don't know how that guy did with the topic, he should be racking his brains and thinking about it now, right?

To Su Yin's surprise, not long after she went upstairs, Hao Youqian gave the correct answer.

"Is there a problem-solving process? Show it to me. ”

"The problem-solving process?" Shaking his head, Hao Youqian said truthfully: "I made up the answer. ”

"Next time, you should set the number a little bigger, so you can't make it up!"

"But I still gave the right answer, even if I win this time, right?"

"What counts as you win, I won, I don't want to compete with you."

Found a blank piece of paper, on which Su Yin listed an equation.

"What the hell is this? Why does it seem so strange? ”

"Don't interrupt, listen to me carefully."

Through intelligent AI, a teaching record was found, and Su Yin explained to Hao Youqian word by word what an equation is and how to solve it.

Listening to Su Yin finish a series of problem-solving processes, Hao Youqian's eyes burst out with a strange light.

Holding Su Yin's hand, he said excitedly: "The equation is really a good thing!" Brother Su Yintai, is there any other similar arithmetic knowledge that you can teach me? ”

"If you can't chew too much, master this first, and I'll teach you other things."

"Okay."

After chatting a few words, Su Yin had a general understanding of the arithmetic knowledge of this era.

The arithmetic knowledge of the ancients was limited to the ninety-nine multiplication table, and multiplication above ten was another unknown territory for them.

As for other aspects, in a sense, the people of this era are very backward in accounting technology.

If you can teach them how to calculate accounts...... It will definitely make a qualitative leap in Jiguo's arithmetic and economy.

Constantly tapping on the table, Su Yin began to think about how to teach Hao Youqian multiplication and division.

When she was a child studying mathematics, she didn't feel bad about it.

But when it came time for her to teach others...... I don't know where to start, it's so hard!

Could it be ...... Do you want to use intelligent AI to find lesson plans?

Seeing that Su Yin was a little distracted, Hao Youqian stretched out his hand and waved in front of her, "Brother Su Yin? Brother Su Yin? What are you thinking? ”

"I'd like to teach you multiplication again."

"You mean Little Ninety-Nine? I've been familiar with this for a long time! ”

The "little ninety-nine" that Hao Youqian said is the ninety-nine multiplication table in the modern world.

Such a simple thing can even be mastered by first-grade children, Su Yin really can't understand: can memorize "Little Ninety-Nine", what is Hao Youqian proud of?

When she thought of the backward arithmetic environment in ancient times, she was relieved again.

"Xiao Jiujiu is such a simple thing, wouldn't it be strange. I'm going to teach you two-digit, three-digit, and even four-digit multiplication. ”

“！！！”

Hao Youqian: Suddenly opened the door to a new world.

"Brother Su Yintai, ah no, Mr. Su, when can you give a lecture to the students?"

"In a few days, there's so much to deal with in this time."

As soon as he heard that Su Yin would be able to teach himself arithmetic for a while, Hao Youqian's eyes suddenly darkened a lot.

I can't learn new knowledge, it's sad!

Taking Hao Youqian's lonely appearance into his eyes, Su Yin thought in his heart: It would be great if Hao Youqian was not Hao Youcai's only son, so that they could be closer. Like what...... tricked him into being the shopkeeper of the accounts.
