Prehistoric I was pinched out by Nuwa

Buzhou Mountain, the territory of the human race.

Houses are built to make the race look larger.

The houses are all made of stone and wood.

If you want to be rich, you must first pluck trees.

Around the territory of the human race, trees were cut down one by one.

The field is opened up, allowing the view to be unobstructed.

If there is danger around, the guards standing on the guard tower can find it immediately.

For the development of the territory, Li Yang does not need to plan too much.

The people of the tribe have lived in the prehistoric world for less than ten days, and they need to receive a little bit of knowledge.

Only by acquiring knowledge can the human race grow rapidly.

What Li Yang knows about cultivation so far is just the breathing method.

He is still figuring out the breathing method, and he dare not teach it to his tribe before he is proficient!

The current development policy focuses on numeracy and calculation, supplemented by word recognition!

Li Yang lives outside the square.

space.

Xia An, the second child, and Ah Xi formed a circle.

They were very quiet listening to Big Brother teach them just.

"Numbers are divided into ones, tens, hundreds, thousands, and tens of thousands."

"For example, 1, 2, 3... 9, this is a single digit!"

"And 10, 11... 99 is a double digit, the latter is a single digit, and the former is a tens digit!"

"The same is true for three-digit numbers, 111..."

Li Yang realized from his second child that when he taught these knowledge, he was not particularly systematic!

He ignores many details.

He made a common sense error.

The tribe should know something.

In fact, the clansmen don't understand anything!

These brothers and sisters will believe whatever they say!

Even if he said 'black' as 'white' and 'white' as 'black'!

Li Yang reflected on himself, whether there will be mistakes in teaching!

And this kind of common sense error, I didn't realize it.

He now quite understands 'I examine myself three times a day'.

Often reviewing or summarizing what you have done will yield a lot.

Just like this morning, he told Ah Xi to deal with monkey brains, thinking that Ah Xi would know which ones were monkey brains.

But thinking about it now, Ah Xi might not know.

Back to teaching, Xia An and the others carefully memorized the knowledge he taught.

Li Yang realized his mistake, and naturally started to make up for it!

He can only say that he tries his best to teach these younger brothers and sisters what he has learned.

After all, he was just an ordinary top three in the school in his previous life, and he had learned quite a bit of knowledge.

I am a liberal arts student myself, and I am not the right major after graduation!

His learning is very limited.

He doesn't even have any teaching experience, so he probably can't compare to those students from the normal university in his previous life in this respect!

There is a specialization in art, Li Yang only learned planning games.

Here in Honghuang, it can only be 233...

After stopping the multiplication teaching, Professor Li Yang, Xia An and the others correctly understood the numbers.

Here, he thought about it and was going to talk about the definition of natural numbers.

The clansmen perform the most basic calculations, so that they will not have doubts about '0'.

After all, '0' clearly means no, so why does it still appear?

Li Yang belongs to solving doubts, not creating them.

"Here, let's first understand a definition! When expressing the number of objects, we can use 1, 2, and 3 to represent natural numbers! If there is no one thing, then here is '0' to represent. And 0 belongs to the smallest natural number !"

Xia An and the others secretly remembered what a natural number is!

The big brother didn't say these before, they only remembered these numbers.

Now that he realized that his explanation was not detailed, Li Yang naturally wanted to explain it again.

As for why 0 is specifically mentioned, it is related to the decimal system.

In front of Li Yang, he taught his people how to know numbers, and only set numbers for his people, these are the numbers!

And the truth, not too much.

Now let's talk about it in detail, so that Xia An and the others can understand as much as possible.

Li Yang only wanted to do his best.

After all, there may be a shortage of knowledge points he taught, but he doesn't know it.

"In addition, before you talk about multiplication, you have to remember that 0 multiplied by any number is equal to 0!"

On Nine Heavens, Wa Palace.

Fuxi frowned, shouldn't Li Yang be teaching multiplication?

I didn't talk about how to go around in a daze.

Although Fuxi was angry, he knew what knowledge Li Yang should be supplementing.

The existence of such knowledge should be more important for multiplication.

Fuxi suppressed his emotions and continued to listen to the lecture.

Li Yang's explanation made Fuxi think.

"It's interesting that nothing can be represented by a symbol like '0'!"

"Natural number? A natural number representing the number of objects? Tsk..."

"It's just that 0 multiplied by any number is equal to 0!"

Fu Xi frowned and thought about Li Yang's statement.

After thinking about it silently, Fuxi thought of the product in multiplication.

0 is put into the multiplication, meaning no bits are accumulated.

Somehow, Fuxi felt that he seemed to have touched this level of knowledge.

After thinking deeply, Fuxi took a light breath.

This human Li Yang's knowledge is so profound.

……

Before explaining multiplication, Li Yang was going to briefly explain the decimal system.

He doesn't know the meaning of the decimal system in the human race, but he knows that the decimal system should be very important!

"Numbers can be divided into individual levels, ten thousand levels, and later larger series!"

Li Yang ignores the subsequent series for the time being.

“何为个级？例如10个1、10个10、10个100、而万级……”

After thinking about it, Li Yang said it out.

The clansmen may not be able to say it, but at least they have an idea in their hearts.

"Such as 10 ten thousand, ten million, ten million..."

"Reminder, all levels also include their results!"

……

As Li Yang gently talked about the decimal system, Fuxi looked at the sky below in horror.

Blossoming golden lotus condenses and blooms, but the merits and virtues condense and have not yet been released!

"Isn't this merit caused by Li Yang?"

Below, Li Yang is still explaining.

"And this method, I define it as 'decimal notation'!"

boom!

The sky is thundering!

Li Yang raised his head suddenly, and the sky flashed with light.

He was dumbfounded, the merit came again?

Can the decimal system attract merit?

Li Yang was pleasantly surprised, but his gaze gradually became dull.

The merits and virtues in the sky are the same as the last few times, condensed but not released!

After teasing him for a while, he withdrew again.

Unwilling to be reconciled, Li Yang used ecstasy analysis.

In the end, there were only six words - the prosperity of the human race, and the decline of merit.

Countless bigwigs in Honghuang, they looked at the merits that had not landed again, and their hearts were calm.

They couldn't figure out the cause and effect, so they could only go crazy!

Heaven will go crazy?

Ah!

The merit is too huge, even they dare not deliberately explore it.

Among all the great powers, only Fuxi sounded faintly.

The merits and virtues emerged several times, all of which started when his sister pinched out the human race.

Human race?

Fuxi gathers below, he doesn't know why the human race can frequently attract merit?

If you add a text tablet and a measuring ruler!

Merits can appear more than four times!

Fuxi looked at his sister.

Ever since my younger sister condensed the holy position and became a saint, she has become more and more unfathomable.

The merit faded away, Li Yang felt regretful but not too much disappointed.

When it should come, it will not run, and when it should not come, it will not come back.

He is only a short time away from merit.
