After becoming a widow, I became the mother of seven children

Yan Qingqing calmed down and continued: "If nothing else, I have a simple and quick counting method that can be used by everything from hawkers doing business to household statistics.

The problems that you usually have a headache about, such as chickens and rabbits living in the same cage, are not problems at all. "

When Yan Qingqing said this, everyone became interested, and they all looked at Yan Qingqing with bright eyes.

Yan Qingqing pretended to cough and said: "Before I teach you these calculation methods, I also need to teach you some simple numbers.

My numbers are different from those we commonly use.

Because these numbers look more like symbols, they are easy to remember and more effective when used.

I named these characters Arabic numerals. "

Yan Qingqing felt a little guilty when she said these words.

What I learned in kindergarten in my previous life was actually used in ancient times to show off.

She was embarrassed whenever a modern child was around.

However, these numbers are really useful, otherwise they would not be universally applicable in future generations.

Yan Qingqing picked up a pen and wrote a few numbers on the paper, exactly one to ten.

Xiao Mochen and others gathered around Yan Qingqing, looking at the strange symbols she drew with understanding.

This should be the Arabic numeral Yan Qingqing mentioned.

After Yan Qingqing finished writing, he said: "This is how one to ten is written in Arabic mathematics, and all the numbers we learn in the future can be composed of these ten numbers."

When Pei Yan saw this, he exclaimed: "This is so simple, I can definitely remember it.

When my dad and mom ask me later, I won’t have to get beaten again. "

He comes from a family of military commanders, so it would definitely be no problem for him to learn riding and shooting, and practice martial arts.

But asking him to recite articles and learn arithmetic would be like killing him.

The main reason why he was asked to accompany the prince was that he was good at protecting the prince.

But as parents, Commander Pei and Mrs. Pei also hope that their children will succeed.

Usually, Taifu Zhao and Taibao Song turned a blind eye to him.

Unexpectedly, Yan Qingqing's simple numbers aroused his interest.

They are all half-grown children, and they all have some skills.

Especially since Xiao Mochen has stayed in the Li family for such a long time and knows something about it, he can learn faster.

Soon the three of them became more and more interested in learning. Even Zhao Taifu and Song Taibao were quietly studying at the side. At first, they could still hold it.

But then I gradually became obsessed with it.

It's just that the two of them are a little older and have weaker receptivity than Xiao Mochen and the others. Yan Qingqing talks too fast and they can't remember it completely, so they will ask a few questions from time to time.

Yan Qingqing didn't hide anything, and would often repeat the story when the two of them asked questions.

But this delayed their study progress, causing Xiao Mochen to look at the two of them with some dissatisfaction.

Song Yanzhi smiled awkwardly and said: "Your Highness, the two of us also want to learn from you. This kind of arithmetic is really novel.

And this Arabic numeral is really easy to use and easy to learn.

Weichen really put a lot of effort into learning arithmetic back then, but today he listened to the Grand Master's lecture for the first time. Although he learned a little slowly, he really benefited a lot.

If it could be extended to the entire Dayan, it would really save a lot of trouble. "

Xiao Mochen nodded after hearing this, but he would report this matter back to his father first, and let the officials in the court and the concubines of the Imperial Academy learn from it first.

But I'm afraid I'll have to tire my aunt again.

Yan Qingqing didn't care. One sheep was herded, and a group of sheep were herded.

After Xiao Mochen told the emperor about this, the emperor was shocked.

He always felt that since Yan Qingqing was the lucky star designated by Qin Tianjian, he should have some skills, such as cultivating high-breed crops and making salt.

But now that Yan Qingqing actually created a brand new arithmetic, he had to be shocked.

To put it bluntly, the status of scholars these days is very high, even the emperor has to look up to them.

Now that Yan Qingqing can teach these people who are highly regarded by the emperor, Yan Qingqing is a talented person in the emperor's heart.

Therefore, the emperor immediately issued an order to let the officials in the court go to Yan Qingqing to learn from him when they were free.

So slowly, more and more people come to the East Palace to study.

In order not to delay Xiao Mochen's study progress, Yan Qingqing selected a few days each month to give lectures to these officials.

Yan Qingqing's status in the capital has risen even more, and storytellers in the streets and alleys are telling stories about Mrs. Mingzhao.

Some people even wrote books and biographies for her, but Yan Qingqing didn't care much about these things.

Busy days always go by quickly, and summer is here in a blink of an eye.

The weather is getting hotter and hotter, and Li Xinniang's belly is getting bigger and bigger, and she may give birth soon.

Yuan Huiniang hired a midwife early and was the most famous midwife in the capital.

He also asked Housekeeper Yu to hire a doctor to live in the house, so that he could diagnose Li Xinniang's pulse at any time, so that if there were any unexpected situations, he could handle them in time.

Finally catching Yan Qingqing free that day, Yuan Huiniang told Yan Qingqing about Li Xinniang.

Yan Qingqing smiled and said, "I feel relieved to leave Xin to your mother. My mother has been too busy during this period. Thank you for your hard work."

Yuan Huiniang laughed when she heard this and said: "What did you say? Mom trusted me to take care of the huge Mingzhao Mansion. It is also my duty to take good care of my eldest sister.

only……"

Yuan Huiniang hesitated for a moment when she said this.

Yan Qingqing saw this and said, "If you have anything to say, just say it. There is nothing else we two cannot say."

Yuan Huiniang approached Yan Qingqing and said quietly: "Wu Jingzhi has been here several times during this period, and the eldest sister also met him twice.

I see that he is very attentive and prepares many things for his eldest sister and children every time he comes. "

Yan Qingqing nodded when she heard this. She had already taken a very open look at this matter and let it take its course.

Yuan Huiniang said mysteriously again: "I heard that the old woman from the Wu family is sick. She is so sick that she can't even get out of bed. She seems to be poisoned."

Yan Qingqing made a sound and pretended not to know, "Have you found out who poisoned it?"

Yuan Huiniang shook her head and said: "It is said that Mrs. Wu was not poisoned, but many people said that it was the concubine of the Qiu family who poisoned her.

Mrs. Wu had promised to let her pass, at least she would be an equal wife.

But after so many twists and turns, she still couldn't enter the Wu family, and the Wu family stopped providing money to the Qiu family of Xishan Prefecture.

Qiu Channiang had become the laughing stock of the family, so she poisoned Mrs. Wu out of spite.

The Wu family has reported it to the authorities, but the Jingzhao Prefecture has not yet closed the case. "

Yan Qingqing nodded when she heard this. It seemed that she was quite merciful towards Mrs. Wu. She just wanted to damage Mrs. Wu's body so that she would not have the energy to trouble Xin Niang again in the future, but as soon as this close niece took action It takes Mrs. Wu’s life.

It’s really wonderful!
