"What, you said that kid ran a night school in the mountains?" "Yes, Your Majesty, since the horse is the last time to enter the mountain, but looking at his disappointed expression, I know that the Taoist leaders did not do anything for him, so he went into the mountain again to gather all the craftsmen, all the old farmers, and announced a thing, that is, to run a night school."

I don't know if Li Er feels bored, so he has been paying attention to everything about Yang Heng, even such a small thing.

"Evening school, literally, is not a place to study at night." "Yes, Your Majesty, the place where they study is in the place where the old farmers grow their crops, because there is a biogas digester there, and there are several biogas lamps that are lit day and night, and there is a relatively large yard in that place, and their study is in that yard."

"I know it, continue to observe, and if there is anything new, tell me as quickly as possible." Okay, you really care a lot Yang Heng cares.

Night school, why does Yang Heng want to open this night school, because since he came out of the mountains last time, he has been thinking about one thing, that is, in general, these subordinates of his have no culture, especially those old farmers, once they find something, they have to wait for someone to go over to check it, and then let the literate people record it, and even miss some important data, how can this be done, but if you change some literate people, but they don't have the ability, Yang Hengyi once thought about whether to assign each of them a recorder, but in the end, Yang Heng vetoed it himself. But the problem still needs to be solved, so he came up with such a solution for night school.

But. Yang Heng's night school was quite timely. It's the old peasants. The craftsmen, as well as those Taoist leaders, urgently need to know more words, and even need some simplified numbers to record some important data, otherwise it is easy to cause confusion if you write in square characters.

This number is naturally the Yang number that Yang Heng named, but it can no longer be called an Arabic number, although at this time Arab countries can have this kind of number. But what they use there isn't necessarily very mature, is it?

"Come, tell me, how many of you are literate?" This is the first class, Yang Heng naturally needs to understand the literacy situation of these people, but fortunately, a few Taoist leaders, and some craftsmen are literate, "Little Niang, you take these illiterate people over there to enlighten, remember." You'll be the teacher of the evening school from now on. "Why is it arranged like this, because Xiaoniang has always had children. also has the ability to enlighten the children, so Yang Heng handed over this task to the little mother.

If you want to say who Yang Heng brought in this time into the mountain, it is naturally Xiao Niang, Changle and Yu Zhang, Yu Zhang is incidental, if you only bring Changle in, and not Yu Zhang, Yu Zhang will be unhappy, especially Xiao Niang, who is definitely the main teacher of this night school, and it must be brought.

"What about me, what about me, who am I going to teach?" Yu Zhang couldn't stand on the side, "You, you can read more than 1,000 words, and you can even slightly interpret some ordinary books." Similarly, the five Dao Masters and a few high-end jewelry craftsmen stood up, "Okay, Yuzhang, bring these people over there, your task is to teach them the Yang number first, and let them learn the Yang number well." ”

Yu Zhang and Changle have been learning numbers from Yang Heng for a long time, and even some general four operations can be, although they are not as good as Xiao Niang, they can teach these people to be, "Changle, look, the rest of the people, you can teach them, it doesn't need to be too difficult, you just need to recognize and write all the thousand-character texts first, and then teach some numbers, okay, let's go and learn each, I will insert some knowledge of things and even chemistry for you from time to time." ”

Yang Heng is not without things, he needs to explain some of the most basic knowledge to them in a few days, in this way, it will make their research go further, and Yang Heng did not set a long time for them to attend classes at night, after all, they still have their own work to do during the day, that is, most of the hour, and they also take a break for a period of time in the middle, that is, they are the time for two classes, these people can only be instilled in it now, and they can't teach it step by step, because they are already stereotyped, You can't teach them in the same way as teaching children, it may take more patience to teach them than teaching children, so Yang Heng asked Yu Zhang to teach those who are the most literate, and it is relatively easier for them to teach.

"What, what are you talking about, that kid actually asked my two princesses to teach those mud legs," "Yes, Your Majesty, the two princesses seem to be teaching what Yang numbers are." The people behind Li Er already know Li Er's temper, once he gets angry, as long as he diverts a topic and diverts his attention, then his fire will be gone, and sure enough, his effect is very good.

"I don't care what number he has, anyway, I can't let my two princesses teach those mud legs, what, what do you say, Yang's number, what's the difference between this Yang's number and the words we use?" Sure enough, Li Er's attention was still attracted, and he even cared about the Yang family's numbers, if Li Er didn't know about the matter, it would be false, but Yang Heng didn't make a big deal about it, it didn't attract people's attention, and now it is only popular in the Yang family and the princess's mansion.

"Ah, I remembered, Yang's number, Yang's number, I seem to have heard who said it, who said it, Changle, no, if Changle said it, then it must be explained clearly, Yu Zhang, not Yu Zhang, she didn't have the patience to tell me what number to say, and if it is said, this is a new thing, she will definitely ask me for a reward, who is it, ah, by the way, go, call Li Zhi to me."

Li Er finally remembered, Li Zhi is Li Zhi, Li Zhi has been to Yang Heng a few times, so it is possible that he learned this number, and when Li Zhi said it to Li Er, Li Er didn't pay attention to what Li Zhi said, just listened, what important things can be said in a child's mouth, and as a result, there are important things in the child's mouth to say.

"Father, your name is Zhi'er." Li Zhi ran in from the outside, "Come, Zhi'er, tell your father, what are Yang's numbers?" "Li Er has the essence of a big bad wolf, and he began to tempt Li Zhi.

"Ah, father, you are going to ask Yang's number, I tell you father, this number is very convenient to use, the master used to teach me to count, I always can't remember, even those calculations feel very troublesome, but since I learned this number, it is a convenience, even the calculation is easy, you listen to me memorize the formula, one plus one ......" Yes, Li Zhi actually memorized the addition formula.

At first, Li Er was still a little impatient, but when he heard the depths, he suddenly realized that this method of learning numbers and addition and subtraction was excellent, so he wanted to know how to write the number of Lu Dao.

"Okay, Zhi'er, you memorize it very well, you have a reward, you can write this word." "Yes, let the sons write to their father." As he spoke, Li Zhi actually took a piece of chalk from the hand of the palace maid on the side and began to write for Li Er on the floor.

What is this, zigzag, Li Er was a little disappointed, but immediately, his thoughts changed. "Father, let the sons tell you that this is a ,...... You see, the son does an addition question, or the father and the emperor will come up with a question. ”

"Okay, one, two, three, add ......" "one, two, three, add ...... The number is ......" This is a bit naïve, but when Li Er saw Li Zhi calculating, he was stunned, this is amazing, just a few simple strokes, you can calculate an equation. "You, I, ah......" Li Er originally wanted to blame Li Zhi for not telling him for a long time, but then he thought about it, Li Zhi had told him that he didn't pay attention.

"Go, Xuanhu Department Shangshu to meet you." …… (To be continued......)
