"Brother Yin, from now on, I can't do it alone, I can't always find the idea to solve the problem, and I hope Brother Yin will help me solve a puzzle." Li Tai bit the cap of his pen and said.

"I'll see." Wang Yin picked up the Olympiad book, quickly glanced at the first grade of the first grade, then turned around, made a thinking appearance, and quickly turned to the final answer page to find the answer...

Made! It's good that my brother has this search function.,Otherwise, it's really hard to pretend.。。。

After reading the answer, Wang Yin secretly breathed a sigh of relief: Fortunately, it is an Olympiad question in primary school, at least this answer can be understood by himself...

"Ahem, the question itself is not difficult." Wang Yin handed the book into Li Tai's hand, with a big hand behind his back: "They are all basic applications of formulas, as long as you find the right breakthrough, you can easily solve it." ”

"Look, draw a line here, split the pattern into a triangle... Wang Yin began to explain to Li Tai according to the answer.

The serious look, as if he really solved the problem himself...

With Wang Yin's explanation, Li Tai's eyes became brighter and brighter, and he subconsciously nodded.

"I see, it's so simple!" After Wang Yin finished explaining, Li Tai looked suddenly enlightened and patted his head: I didn't expect it to be so simple, it's so stupid!

Thinking of this, Li Tai thought for a while, then turned to another question and buried himself in the calculation.

Two minutes later

Li Tai checked the answer twice, raised his head contentedly, and stretched.

Wang Yin's heart suddenly said '' again: This Nima, touch the bypass? It deserves to be a top student... Sure enough, it's a creature that is afraid...

As a prince, this baby didn't engage in politics but studied these things, which is obviously the wrong skill tree, right?

"Can't be sure, can this Li Tai really become the first mathematician and scientist in Datang?" Wang Yin looked at Li Tai with a satisfied smile on his face, and thought in his heart.

Li Yuan is better, he also knows what level he is, and he is not surprised if he can't understand it, but he is happy to see Li Tai touch the class bypass to solve the previous problem.

Kong Yingda is a complete Sparta...

What did they just say?

Line segment? Area? Square?......

What the hell is this? I don't understand it at all, huh?

Could it be that all the arithmetic I learned before was fake?

At this moment, Kong Yingda had deep doubts about the knowledge she was proud of...

"His Royal Highness King Wei, what are these so-called 'line segments', 'areas', and 'squares'?" Kong Yingda asked his doubts.

"This..." Li Tai hesitated, where did he start at this moment?

"Uncle Kong, don't make a mess, if you want to go back and learn from scratch, you don't understand it now." Wang Yin rolled his eyes helplessly.

Hearing Wang Yin's words, and then looking at Li Tai's hesitant and tangled expression, Kong Yingda instantly felt disgusted...

No, is it really good for you guys to do this?

Don't you even know about the elders?

This will make the old man very sad!

"What do these strange words mean?" Kong Yingda is also a doer, and when he saw that he couldn't figure out these basic knowledge for the time being, he shifted his attention to the letters.

"This thing, letters, for marking." Wang Yin looked at it and said.

"What is a letter?" Kong Yingda continued to ask.

"Letters are used for marking." Wang Yin pointed to the dots marked by the letters on the title: "Otherwise, you can't say this corner here, that line over there, so people can't understand it." ”

Kong Yingda thought for a while and found that what Wang Yin said was really reasonable.

With these 'letters', people can instantly intuitively see the meaning of the question, which is really very convenient.

"Wonderful, wonderful." Kong Yingda stroked his beard and nodded.

"And how do you pronounce these letters? But what other uses are there? Kong Yingda continued to ask.

"Really." Wang Yin said: "Speaking of which, this recitation and use are still one. ”

Speaking of this, Wang Yin took the paper and pen on the table and wrote the word 'Wang', dyed it red and marked it with pinyin and tone.

"You see, this is my surname, and the one on it is the pinyin of the letters." Wang Yin pointed to the things on the paper and explained, "These four letters are wu a

e ge, but the a behind this one

e ge three is to be read together, read as 'ang', you connect and read it. ”

Kong Yingda thought about Wang Yin's words for a moment when he heard this: "Wu... Rise... King? ”

"Yes, but this tone is four tones, and the slash above is the tone."

Not only Kong Yingda, but a group of people are all in the clouds.

The main reason is that Wang Yin is too messy, and he stuffs so many things at once that he can't understand them at all.

Wang Yin himself discovered this problem, so he thought about it for a while, took out a new piece of scratch paper, and wrote out the pinyin letters one by one on it.

"These are called pinyin letters, and the sounds we usually make when we say them are made up of these." Wang Yin pointed the letters one by one with a pen and taught them one by one: "This letter reads 'ah', this circle reads 'nest', and this letter reads 'e'。。。。。。 ”

Wang Yin spent an hour explaining the initials and finals to the group, during which he had to correct the mistakes and answer some of their questions.

At this moment, Wang Yin suddenly had a rush to teach a group of kindergarten friends.

Thinking of this, Wang Yin glanced at the crowd: Well... It's just that this little pot friend's age is a little overclass.。。。

"You can try to put your name in pinyin." Wang Yin suggested to them, and sent a few more gel pens down.

The first time they came into contact with this kind of knowledge, everyone was very curious, and felt that it looked very interesting, so they picked up the pen and paper and began to write and draw.

Not surprisingly, Xueba Tai was the first to successfully complete the task, and the writing was completely correct.

The second one written correctly is Kong Yingda, well, doctor, there's nothing wrong with it~

And then... There is no then ...

Li Yuan spelled his name as 'li ya'

’。

Cheng Lingxue spelled out a 'che

li

xe’。

Well, it's worthy of Cheng Biting Jin's daughter...

To be expected...

Wang Yin picked up the pen and revised it on their paper, and the name was finally correct.

"It's okay, it's normal to be slow to learn things when you're old." Wang Yin patted Li Yuan's shoulder and comforted.

Li Yuangang breathed a sigh of relief, and then realized that something was wrong: Are you kid comforting people? Didn't you see that Kong Yingda was bigger than me? . .

"You are not to blame for the genetic problem." Wang Yin patted Cheng Lingxue's arm.

Cheng Lingxue: Genetic problems? What do you mean? Brother Yin said don't blame me? That's not because I'm stupid.

Cheng Lingxue, who 'figured it out', immediately became happy again: "It seems that I'm still very smart!" ”

"From this point of view, if you master these 'pinyin letters', wouldn't everyone be able to read and write?" Li Yuan is worthy of being an emperor, and he immediately grasped the key point.

"That's right, that's how we all came to kindergartens there." Wang Yin looked at their confused expressions and explained: "It's those children who have just started learning." ”

Hearing this, everyone suddenly realized and nodded secretly.

"After learning pinyin, it will be much easier to learn words in the future. As long as you mark the words with pinyin, you can pronounce them even if you can't write. Li Tai bit the cap of his pen and said.

Hearing Li Tai's words, Li Yuan instantly became excited.

If it is promoted according to Wang Yin's method, won't the people of the Tang Dynasty be literate in the future?

Thinking of this, Li Yuan almost fainted with happiness...

"But if you mark all the words in the world, I'm afraid it's not an easy thing." Kong Yingda expressed his doubts: "And if you encounter words that you haven't seen before, wouldn't it take a lot of time to look them up one by one?" ”

"So there's such a thing as a dictionary." Wang Yin posed and said.

"What is a dictionary?" Everyone asked in unison.

"Before we talk about dictionaries, let's talk about radicals." Wang Yin said, and took out a book of radicals.

No way.,Pinyin can still be remembered.,There are too many radicals.,The ghost remembers it.。。。

It doesn't matter if you can't remember, just have a book...

In the next hour, Wang Yin explained the radicals, and unsurprisingly, Xueba Tai was still the first person to figure it out.

And what's even more terrifying is that this product has copied all the radicals on the book, and the reading method is also marked in pinyin. . .

Wang Yin looked at Li Tai again as if he had seen a ghost: What the hell are you a god and horse freak, even if you are a scholar, your memory is still hot...

Wang Yin looked at Li Tai, and then turned his head to look at Cheng Lingxue: There is no comparison, it hurts...

"Brother Yin, what's wrong?" Cheng Lingxue couldn't help but wonder when she saw Wang Yin shaking her head at herself.

"Nothing... Wang Yin patted her shoulder gently: "You're fine... Not bad... ”

Cheng Lingxue looked at Wang Yin with a confused expression: Why do you feel that Brother Yin's tone is weird? Forget it, just know that he's praising me anyway!

"His Royal Highness the King of Wei has a high opinion, so that it will be easier to remember." Kong Yingda slapped the fart lightly.

Seeing his grandson give himself such a long face, Li Yuan rubbed his beard and smiled with satisfaction.

"If you understand the radicals, the dictionary will explain them easily." Wang Yin picked up the pen and wrote on the paper, and began to draw.

"There are three ways to look it up in the dictionary... Wang Yin explained while demonstrating on paper.

After everyone figured out what Wang Yin meant, they were all shocked again.

"With this dictionary, there will be no illiterate people in the world in the future!" Li Yuan said excitedly and loudly.
