As soon as Zhou Xiaocao said this, the classroom began to buzz. How so? Teacher Zhou wants to show everyone a hand first? That's good, if it weren't for the face of Boss Feng and Boss Zhu, who would believe in the ability of an offspring. Oh, I've been in charge of the account for decades, but it's better for you to play with a young child? Joke!

Zhou Xiaocao pointed to the white-bearded old man who spoke just now and said: "This old gentleman's age is extremely fair, so let's let this old gentleman come up with the question and be the judge, who will compete with me?" One or several! ”

As soon as Zhou Xiaocao's words fell, he saw Xing'er stand up and say loudly: "Let's come, let's compete with you!" ”

Zhou Xiaocao had a headache when she looked at these two girls, but she had no choice but to say to the old gentleman: "Old gentleman, please ask the question." ”

The old man twisted his beard, nodded and said, "It's rare that Zhou Gongzi believes me, the old man has been a bookkeeper for forty years, and he is the person here, and there are many apprentices brought out by the old man." Listen, this question is, if a shop has an average daily income of one or two or seven dollars, what is the approximate income in a month? ”

Seeing Xie Qiuyan and Xing'er immediately take out the abacus and pull it up, Zhou Xiaocao laughed wildly in his heart. Wowhaha, even if my brother doesn't have a calculator, I can choke you with my mouth!

Zhou Xiaocao began to calculate in his heart: one tael of seven coins of silver a day, ten days is seventeen taels of silver, seventeen taels multiplied by three, that is fifty-one taels!

"I calculated it, a total of fifty-one taels of silver!"

Zhou Xiaocao calculated so quickly, which really surprised everyone. One or two seven dollars, multiplied by thirty days, how did he calculate so quickly?

The white-bearded old man said: "Well, Zhou Gongzi has already figured it out, what is this... Childe, have you figured it out? ”

Xie Qiuyan went into battle with both hands, the abacus crackled, and said, "Wait a minute, it's almost time to figure it out." ”

Zhou Xiaocao squinted his eyes, one leg trembled, and his heart said small, fight with me, you are still a little tender! But I like it! The more tender the better!

After a while, Xie Qiuyan also calculated it, looked at the number on the abacus and replied: "A total of forty-three taels of silver, I don't know if what I said is right or not?" ”

Zhou Xiaocao smiled happily: "Wowhaha!" You can still be wrong with the tools, and I'll laugh! Wowha, I really laughed to death! ”

The white-bearded old man said, "Master Zhou, you miscalculated. ”

Zhou Xiaocao thought that there was something wrong with his ears, or something was wrong with the old man's mouth, so he asked repeatedly, "What did you say?" Who miscalculated? ”

The white-bearded old man said to Zhou Xiaocao word by word this time: "That's right, you miscalculated, Zhou Gongzi, you miscalculated, it should be forty-three taels of silver." ”

Zhou Xiaocao tilted his face and looked around, only to see that all the students nodded at him calmly, which means that you have indeed miscalculated!

"How so? How could I be wrong?! ”

Zhou Xiaocao sat on the chair on the podium and said, "Listen up. It's one or two or seven dollars a day, and we're going to break it down into three ten days. These ten days are seventeen taels of silver; Seventeen taels of silver multiplied by three, let's divide seventeen again, ten times three by thirty, seven times three twenty-one, twenty-one plus thirty, no more, no less, exactly fifty-one taels of silver! ”

The white-bearded old man sounded fine in front of him, but his face changed dramatically when he listened. Not only him, but everyone in this room looked at him like a monster, which made Zhou Xiaocao very embarrassed. If it weren't for the fact that there were basically men here, if they were all like Xie Qiuyan's master and servant, Zhou Xiaocao would have thought that everyone in this room had taken a fancy to him.

"It's... Is there something wrong? ”

Facing Zhou Xiaocao's doubts, in the end, the white-bearded old man had seen a lot of the world, and at this time he shook his head and said, "Hou Shengzi, you are not right like this." Did you know that a tael is sixteen dollars? ”

"Huh?!"

I've wiped it, and I have calculated thousands of dollars, but I haven't counted that one or two in ancient times is sixteen dollars! That seven dollars is not 0.7 taels, it's all wrong!

"Hey, you can't teach it, you don't even know that one or two is sixteen dollars, how can you teach us? We asked for a refund of the tuition, fifty taels of silver! ”

"Yes, yes, we will also compensate us for mental damages!"

Faced with the strike of a large group of students, the cold sweat on Zhou Xiaocao's face came down, what can be done?

In the midst of the bustling crowd, a voice shouted, "Stop! Stop! ”

But there are so many people here, how many people will listen to her?

"Shut up! I am the daughter of Lord Xie, the prefect, if you don't stop talking, I will go to my father to sue you! ”

This sound really worked, and it was cold all of a sudden. Zhou Xiaocao, who had lost at home, let out a sigh of relief and said to Xie Qiuyan: "Thank you, sister of the Xie family." ”

Xie Qiuyan pursed her lips and said, "If you say that again, I won't care about you, just let them kill you!" ”

Zhou Xiaocao said: "Hehe, you are reluctant... Uh, okay, I don't speak, can't I not speak? ”

Xie Qiuyan glanced at Zhou Xiaocao and said, "Everyone, Zhou Gongzi is not a person in charge of accounts, and it is normal not to know that one or two is sixteen yuan." But, I don't know if you've noticed, when he just counted, the kind of algorithm that was disassembled and closed was not very novel? ”

"yes, that's a really good idea."

When everyone heard Xie Qiuyan say this, they all woke up. Although Xiaocao has no common sense this week, the algorithm just now is indeed very fast. Isn't it, that's what the legend says|" Zhou's notation"?

Speaking of which, with Boss Feng's cleverness and Boss Zhu's guarantee, how could he find a fool to fool everyone?

Zhou Xiaocao said: "Did you hear that? The algorithm just now is the multiplication, distributive and associative properties in Zhou's notation. By the end of this training, I promise you all are masters! ”

finally relied on Xie Qiuyan's identity as the daughter of the prefect to temporarily suppress everyone, but Zhou Xiaocao knew that this was just the first step. In the next 20 days, if Zhou Xiaocao's Zhou counting method cannot satisfy everyone here, it will be good-looking. But for this counting method, Zhou Xiaocao is still very confident.

That is, the advanced methods of the later generations, put them in this time and space, can they not be advanced?

Zhou Xiaocao cleared his throat and said, "Okay, now let's start the first lesson, learn Zhou's numbers, there are zero to ninety basic numbers......"

The first day finally passed without danger, but on the second day, Zhou Xiaocao found out that this group of people was really a group of fucking scum! Any kind of crooked idea can be come up, why don't such people go to hell?

He forgot about it, isn't he himself a scumbag who is bad to the bone? This animal, that is riding a donkey to find a donkey, even with himself is scolded.

As for why the teacher is so angry this week, the reason is that yesterday I looked at the classroom with so many big holes, and today I came to see that the room was full of people!

Zhou Xiaocao was surprised: "Why are there so many people all of a sudden?" ”

The white-bearded old man from yesterday's referee pointed to the middle-aged man beside him and said, "This is my scholar." Since Miss Xie can bring the scholar over to the class, so can I. ”

Zhou Xiaocao had a big headache: "I said, it's too much for you to do, right?" Return the bookboy? Is there anyone who is a bookkeeper and a scholar? And you, yes, it's you, you have three scholars? I'll go, and the uncle over there, your scholar is older than your father, and you're embarrassed to say it's your scholar......"
