Sun Yingying smiled and said, "yes, these arithmetic knowledge is very interesting. Some are simplified according to our existing arithmetic. After all, they are all words and are too complex, so they want to simplify and replace them with special symbols. I wonder if Yingying has the honor to explain the new arithmetic for his majesty and prince?"

Emperor Kangming and crown prince Bai Yishan were very satisfied. Sun Yingying was smart and transparent. She didn't need them to take the initiative to mention it. She took the initiative to mention it.

Sun Yingying saw that there was no blackboard or chalk in the office, which was not suitable for teaching. "Your Majesty, Prince, please move to the classroom, where there is a blackboard for explanation."

"Well, Yingying leads the way." emperor Kangming and crown prince Bai Yishan readily agreed.

That is, today, the Duke of the town is idle. He also came to his granddaughter's academy to have a look. Naturally, he saw the man who was taking emperor Kangming and crown prince Bai Yishan into the classroom.

Of course, the Duke of the town can't let sun be alone with his majesty and the prince.

Not even the classroom. After all, one is the future father-in-law and the other is the future brother, which is not polite.

Coincidentally, Gu juecheng, king of Jinghai, accompanied sun Meimei to the Academy today. They were curious to see what sun Yingying looked like in class.

So at the end, there were five people in the classroom: Emperor Kangming, crown prince Bai Yishan, Duke Zhenguo, King Jinghai, Gu juecheng and sun Meimei!

Caihe is very thoughtful. He has borrowed five books from the students and put pen, ink, paper and inkstone in front of them.

Sun Yingying looked at the older students below, some crying and laughing, but also very excited, and then began to explain from 1, 2, 3.

Addition and subtraction multipliers... And so on!

Those who sit next are very smart people. They learn new things with high efficiency and are good at accepting new knowledge.

With sun Yingying's explanation, these people's eyes are brighter and brighter······

Alas, the new arithmetic, combined with the previous written arithmetic, can perform calculations more quickly, correctly and effectively.

At noon, I still used wooden plates in the canteen and ate a fast food before leaving.

It's just that when they left, they took away the primary calculation books over there.

Those books were temporarily borrowed by Caihe from his classmates, but now they are taken away by these big people. So Caihe can only go to the warehouse to find five books and return them to these students.

The content of sun Yingying's class was very interesting. After Prince Bai Yishan returned, he discussed with Crown Princess Yu Wanyi and directly sent the big princess to sun Yingying. It was called let Sun Yingying teach.

The big princess has long thought of the palace. Her father is the prince and has always lived in the east palace.

Except when she grew up, married and was able to leave the palace, she was rarely allowed to come out. But now I can go out of the palace every day by reading with my second aunt in the future. It's great.

Later, the big Princess directly relied on Sun Yingying to eat and live with her.

The three accompanying readers of the big princess are also the daughters of xungui's house.

Now the big Princess studies with sun Yingying, and these people naturally want to follow.

One come and two go, these little girls like this teaching method.

So the prince directly arranged for the respected Master to come to the academy to teach the contents of the four books and five classics.

There are two hours of classes every day, and the rest of the time is used to study the courses in sun Yingying college.
