Xu Lao didn't expect Mo Yu, who had always been very educated, to say such a thing, and his words couldn't help but be a little harsh.

Mo Yu heard Xu Lao treat herself like this, just for that woman, and suddenly felt that there was something between them. He couldn't help but look at Xu Lao, and his tone was very unpolite. "Teacher, it's not me talking nonsense, I guess you can't believe it, she didn't even move the pen, she can directly report the answer. There are so many of us who have abacus in their hands, and it takes so long to count, let alone someone who doesn't hold anything in her hands. Could it be that she is really a god operator. ”

Originally, those people had some reservations about Shen An'an's arrogant attitude, but at this moment, as soon as Mo Yu's words were spoken, they were suddenly like a big stone, and suddenly they were thrown into the water, and one stone stirred up a thousand waves.

"yes, it must be cheating."

"I guess I knew the answer in advance, it's a little girl, what kind of god operator will be there."

"I don't think it's that Old Xu looks at other people's faces and looks good." The person who spoke, his eyes were restlessly rolling around Shen An'an, but he was immediately hit on the head by the person next to him.

"Hugh is talking nonsense, things may not be as we think, don't you see that people are not panicking at all."

"Really? How I didn't see it. ”

"Because you're a pig!" A woman next to her said.

The others couldn't help but laugh when they heard this.

Gags, and then let's get down to business.

"Hmph, if you can't do it yourself, you doubt the ability of others, my Lao Xu guarantees with personality, I have absolutely not leaked the answer to anyone, including An Yatou. I'll be honest with you, this is a topic that I just got my hands on. ”

Seeing that Xu Lao was angry, and his face turned red with anger, he also vouched for his personality and swore an oath, which means that he really has not done such a thing.

"Let me explain it to you, it's actually just a very simple arithmetic problem of addition and subtraction."

After speaking, he saw Qing Ying and Chu Lin quickly staring at a very large piece of white paper on the black wooden board, and Shen Anan picked up a homemade charcoal pen in his hand and began to write on it.

What she wrote was a simple arithmetic solution, a columnar algorithm that even elementary school students can do in modern times.

"First of all, let's look at the problem, the farm sold 500 piglets in January, and 200 more piglets in February than in January. So let's say that there are 200 more heads in February than in January, so we use our simple formula: 500 + 200 = 700 (heads). ”

After seeing Shen An'an write this strange formula, he immediately changed the conversation: "But this is not the final number, because the pig farm lost two more piglets in the process of transportation, so the total number must be sold less than ten piglets, so we must subtract when we do the calculation." After Shen Anan finished speaking, he wrote another 700 minus 10 words.

"That's what it looks like."

After speaking, Shen Anan listed a subtraction formula. 700-10 = 690 (head).

After speaking, he looked at those ignorant people and said: "You don't have to look at me like this, I also learned this addition and subtraction method from a teacher, and she taught me such a simple method of arithmetic."

Actually, you don't need to look at the two zeros after the hundreds, as long as you copy it. "Behold, what is five plus two?"

Seeing Shen An'an stretch out the fingers of his two hands, then put them together, and said: "So, I can calculate with my mouth like this, there is no need for abacus at all, if you feel unconvinced, I can continue to compare with you." Or which of you debuted on the topic, let's count it together. ”

Shen An'an's arithmetic and Arabic numerals written on the white paper are very large and neat, and the words they wrote with a brush are like two styles, but they are not ugly.

But what shocked everyone even more was not Shen Anan's charcoal words, but the equations she listed.

"May I ask Mrs. Shen, what are the magic horses you wrote about those strange circles, why can you calculate that question so quickly."

The question asked by this person is estimated to be a topic that most of the people present are concerned about, so everyone looked at Shen Anan very nervously.

Shen Anan looked at Sanniang with a smile and said, "Sanniang, I'm a little tired, why don't you tell everyone about it." She had already told everyone the answer, but they still didn't understand.

"Madam, I, I'm afraid I won't be able to say it well." Sanniang saw that Shen Anan let herself go out to explain to everyone, and her little face changed in fright.

Madame, is this joking with her? She was very timid, and she was afraid that if she said something wrong, those people would attack her.

What to do? Who's going to save her and give her faith?

"You have to believe in yourself, what I taught you in the house, you just tell them." Shen An'an followed the temptation and gave Sanniang in distress a trick.

Sanniang's eyes rekindled a glimmer of hope, and asked weakly, "Is this okay?" ”

looked at the people opposite, as if they were going to eat people, and the boy sitting opposite, the man with cold eyes, was so fierce just now.

"Well, believe me, what you say is more convincing than what I say."

Sanniang didn't understand what Shen An'an meant by this, but she knew that there was a rule, as long as she listened to Mrs., it would be right, because Mrs. was the best.

This is also the reason why Shen Anan likes Sanniang very much, she has a strong execution.

So Sanniang stood in front weakly, and it was the first time she had seen so many people. It was the first time to speak under the gaze of so many people, if it weren't for the fact that Shen An'an was behind her to encourage her, she would have walked out with her lady's hope.

She does not represent herself, but the Li family, and her performance today is more about the face of their Li family.

Thinking of this, she was not so scared in her heart.

According to what her wife usually taught her, as long as she encounters her own fear, she will take a deep breath and breathe in the middle of the heart, which will relieve the pressure in her heart.

She took a deep breath, then opened her eyes, and thought that everyone below was cabbage.

In the face of cabbage, she was not afraid.

"Hello everyone, my name is Sanniang, and I am a descendant of the Li Mansion."

"Poof, ahaha." As soon as Sanniang's voice fell, several officials on the opposite side laughed loudly, and the laughter was so exaggerated. But then their voices stopped abruptly, as if someone had directly choked their throats.

Only then did they see that it was Mo Yu and Xu Lao, as well as Ning Zhifu and Mu Da over there, and looked at them.

Suddenly, like turtle grandchildren, they immediately closed their mouths.

"I don't blame you for laughing at me, because it's not the adults standing here, it's the sons and ladies of the adults, and I'm very satisfied that I can stand here and talk to you today. But I can tell you right now that I'm going to do that too. ”

When the people next to him heard this, they immediately began to coax.

Mo Yu couldn't help but look at Shen An'an, as if asking, what are you doing, you actually used a girl to fool me.

Shen Anan made a gesture to him, please be patient.

So Mo Yu stopped talking, but looked at Sanniang to see what she wanted to do.

Shen Anan didn't explain to them herself, but let a girl who didn't understand anything come out to speak, was it a contempt for them, or something else.

Shizi, who was sitting here, couldn't sit still, so he couldn't help but ask Li Sheng again. "Ann girl, what are you doing here?"

This time, Li Sheng knew Shen An'an's intentions, and couldn't help laughing: "It turns out that the prince has no patience, of course you have to be a little patient if you want to watch a good show." ”

Shizi couldn't help but glance at Li Sheng with disdain and said: "It seems that you are really a husband and a wife, let me ask, you are so stingy that you don't even tell me." ”

Li Sheng saw Shizi say this: "I don't know if I guessed correctly, in short, some time ago I saw my lady who once taught this set of arithmetic methods to those people in the house, I think today's question should also have something to do with those calculations." ”

"So, you'll do it too?"

Li Shengcai would not admit that he would not do it, but replied vaguely: "It's so-so." As soon as he finished saying this, he said in his heart, it seems that he has to learn this method of arithmetic, in case someone uses this as a rhetoric to embarrass him in the future, he can't go out of the way. After all, what kind of addition and subtraction is this set, even the maids in the house have learned it, can he, the master's family?

What's more, the method used by Shen An'an is really easy to use, and even Moyu has been calmed down. Although Bai Sihuan didn't say anything, he also made a bet on the bone folding fan.

Of course, looking at the current situation, I am afraid that it is the piece of the prince of the world, and the beautiful jade of the family, which will not be able to be saved.

I saw Sanniang holding the strange pen that Shen Anan had used just now. This is not a brush, nor a red pen, but a slender, black fire stick is not an exaggeration.

The stick was about the thickness of a thumb, with some pointy points in the front and a circle of stuff wrapped around it. This was wrapped in paper by Shen An'an, in order to prevent his hands from being blackened.

However, it is quite convenient to see Shen Anan and Sanniang using it, and when they write, it seems to be very fast.

I saw Sanniang holding the charcoal pen in her hand, and her movements were very clumsy, but she wrote very seriously with one stroke and one stroke.

The first one is a circle circle. The second number is a vertical, the second number is a curved head plus a horizontal one, and the last number is a circle with a curved little tail underneath.

From 0 to 9, Sanniang spent a lot of effort, because the pen she held in her hand was always disobedient and kept sliding down, so she held it tighter.

Fortunately, the few numbers she wrote, although they were all crooked, not as good as Shen An'an's writing, but they were written very clearly and very clearly.

But seeing the reaction on everyone's faces, Shen Anan knew that he had guessed correctly.

Such a thing, said through Sanniang's mouth, and said it herself, which is completely different from the feeling for everyone.

Those who have listened to Sanniang's explanation will definitely think, what a little maid can learn, can't we learn?

A topic that a maid will do, it shouldn't be difficult.
