Gu Rao coughed lightly.

"I'm so much younger than you, let you worship me as a teacher at a lot of age, it's embarrassing, forget about apprenticeship, just give me ten taels of silver."

"Give me the money and I'll teach you arithmetic."

Gao Caitong is very persistent in this matter.

"Since the ancient masters are teachers, your achievements in arithmetic are probably not even comparable to some professional scholars, I worship you as a teacher or I take advantage."

"How can ten taels of silver be enough?"

"Fifty taels of silver, if the teacher thinks it's not enough, he can add more."

This is the first time that he has been in business for so many years, and when others give a price, he does not press it down, but raises the price himself.

It can be seen that the importance attached to apprenticeship.

Gu Rao didn't expect that there would be an accident.

She certainly wouldn't refuse.

But fifty taels of silver is enough, and no matter how greedy you are, it will look ugly, "I will teach you everything I have learned all my life with all my heart." ”

Gao Caitong knelt down and gave Gu Rao a cup of tea.

Although Gu Rao was not used to it, she still cooperated with Gao Caitong to drink Jingshi tea, originally just for money, but after drinking Jingshi tea so solemnly, she really regarded Gao Caitong as an apprentice in her heart.

Write down the addition table right now.

In order to make it easier to calculate, the Arabic numerals are used.

Gao Caitong looked dazed.

"Why don't I recognize any of this?" Without waiting for Gu Rao to answer, he suddenly thought of Gu Rao's mental arithmetic ability, and said excitedly, "Is this the unique secret of your mental arithmetic ability?" ”

Gu Rao nodded.

"The words on this are Arabic numerals, I wrote you an addition table, teach you to do addition first, and after you memorize the addition formula, I will call you the subtraction formula, multiplication formula, and division formula."

"When I learn addition, subtraction, multiplication and division, I can easily calculate small amounts without using an abacus in the future."

"If you still want to be able to calculate large numbers quickly without using an abacus, you have to continue to learn addition formulas, subtraction formulas, multiplication formulas and division formulas."

"When you learn this, you can easily calculate the amount of money."

Gao Caitong asked, "If you learn what formulas and formulas you said, can you easily calculate the problem I just gave you just now, just like you?" ”

Gu Rao shook her head.

"Formulas and formulas are just getting started, and if you want to be like me, you still have to learn a lot of things."

Gao Caitong's eyes that were not too big burst out with a thirst for knowledge.

"I'm going to learn!"

Gu Rao, "......"

I suddenly felt that teaching an apprentice is not an easy task, especially in learning, such a proactive apprentice!

What's going on with a lot of pressure?

Tell yourself that you have received the money and drank other people's apprentice tea, and now it is too late to regret it, teach it patiently, as long as he wants to learn, he will teach it himself, and how much he can learn depends on his own ability and creation.

"Take your time, you can't get a big fat man in one bite."

Gu Rao admits that she is not a patient person, especially when it comes to teaching others some basic things, but Gao Caitong looked at the addition table with a blank expression, which still made her realize that she hadn't even taught him Arabic numerals, so she let him learn the addition formula first, which was a bit of a tower.

So I was patient and wrote another Arabic numeral from one to one hundred, and under the number, I wrote the words "The era from one to ten".

"1 is one, 2 is two, 3 is three......"

"The Arabic numerals above correspond to the numbers below, you can read them a few times with me first, and slowly become familiar with these Arabic numerals."

Gao Caitong obediently read aloud.

After reading it several times, I finally understood a little meaning.

"Master, if I use the numbers you taught me to keep accounts in the future, wouldn't it be much easier? These Arabic numerals seem so easy to write! ”

Gu Rao snorted.

"Did you learn?"

Gao Caitong said honestly, "I will read it along, but as soon as I leave this piece of paper, I guess I can't remember how to read these numbers." ”

So, he still couldn't read the addition table alone.

Gu Rao said again, "You not only have to read, but also write, let's teach here today, you follow this piece of paper, write the things on it a hundred times, and after you finish writing, come to the third house in the stone bridge of South Street to come to me, and hand over the written manuscript to me for checking, if there is a mistake, continue to correct it, if there is no mistake, let's start learning addition." ”

Gao Caitong hesitated for a moment, but still couldn't help asking, "Master, can I study with my son?" I only have one son, and the family business will definitely be handed over to him in the future. ”

Gu Rao nodded.

"Yes, you can learn whatever you want."

"You can do it."

Gao Caitong's eyes lit up.

"Master's atmosphere!"

"Don't worry, my son won't learn in vain, and he also needs teaching fees, but he is my son in the end, and if I worship you as a teacher, my seniority with him will be messed up, so can you let him worship me as a teacher and be your apprentice?"

"In the future, if other people want to learn, I will introduce it to the master, and the master will accept it if he wants to, and if he doesn't want to accept it, I can accept it, you can be their ancestor!"

"Such a good thing can't be taught to others in vain, we can use this method to earn a lot of money...... You can start with half a private school and specialize in teaching mathematics! ”

Gu Rao, "......"

Should it be said that it is worthy of being an old fritter who has been immersed in the mall for many years? You can think about anything in business, but it's ...... His proposal is not impossible to try.

Running a school to teach, not only to earn money, but also to promote the cultural development of this era, is it also a good thing, isn't it the best of both worlds?

Moreover, teaching one person is teaching, and teaching a group of people is also teaching, so why not spend energy once and teach more people to come out?

seems to have seen Gu Rao's heartbeat.

Gao Caitong continued, "Master, you don't have to worry about running a private school, I have a lot of real estate in my name, when you have time, come with me to choose a place to use as a school, if you really have the intention of running a school, I can start recruiting people now." ”

The corners of Gu Rao's mouth twitched.

"You haven't learned much from me, so you hurriedly helped me run a school and recruit students, aren't you afraid that I am actually an empty shell and will waste so much energy on you?"

Gao Caitong looked trusting.

"How can the master be arrogant?"

"Even if the master will not know anything else except teaching people these Arabic numerals, there will definitely be people who are willing to follow along, these numbers are much more convenient and faster to write than the numbers we usually write, if you really learn them, you can save a lot of pen and ink when you use them in the future."

Gu Rao patted Gao Caitong's shoulder with relief, and took out the fifty taels of silver tickets that had just been handed and had not yet been hot, and stuffed them into Gao Caitong's hands.

"This silver is my investment in the early stage of running the school, and now I will hand over the silver to you, and the matter of running the school and recruiting students will be fully handed over to you."

Although she did have these thoughts, she still felt that it was a bit too playful, and she might not receive too many students at first, so she didn't bother to spend too much energy on it.
