Prehistoric I was pinched out by Nuwa

In the prehistoric world, the inheritance of the dragon, phoenix, and unicorn races originated from the memory of bloodlines, and if the clansman existed, the inheritance was extremely difficult to break.

The human race is different, not to mention ignorant at birth, and there is no inheritance.

If the human race wants to be strong, they can only learn by themselves, and have nothing to rely on.

And Li Yang took the lead in compiling the characters of the previous life, so that the race could have a channel for inheritance.

Just like this, he passed on the knowledge he had learned in his previous life to these newborn tribesmen.

There is more than time and space between him and his previous life, and he can still pass on what he has learned to his tribe!

The rest of the tribe learned this, and the same is true.

The river of human knowledge in the previous life is so majestic, Li Yang's knowledge is only a drop in the ocean.

Even the top scholars who have come to the forefront of the world dare not say that they understand everything!

The human race has thousands of years of knowledge, all walks of life, all kinds, and everyone is a part of it.

What I am good at is nothing more than the industry I am in contact with, and the rest of the knowledge I have dabbled in is just because of interest.

The knowledge of the previous life is too vast, and choosing one of them can make the current tribe stand firm in the prehistoric.

In the previous human race, Li Yang once heard from his grandma that the two words he would shout were 'Mom', and the rest were 'Dad' and 'Grandma'.

Later, it is parents who teach him how to know numbers.

If you can say 12345, both parents will be happy and smiling.

Neighbors and relatives will even say, "It's amazing, I must study hard in the future"!

Li Yang was obsessed with games, skipped class at night and went to an Internet cafe for a night, but he didn't become someone else's child in the end.

Later, he felt remorse and studied hard to be admitted to a 985 category school.

Became the child of other people's family saying that "others can be admitted to university without studying".

There was no pride in the previous life, Li Yang felt a little emotional whenever he gave lectures.

He is finally no longer a carefree three-year-old, and now there are thousands of clansmen headed by him, who need him to take the helm and set sail.

Based on numeracy, the progress of the tribe has actually been rapid.

The four arithmetic calculations are performed one day at a time, supplemented by other methods during the period, so that the clansmen can be confident that they can master no super-classes.

Human territory, in front of the new log cabin.

Li Yang starts division teaching.

The environment was still not very particular, and several people sat cross-legged in a circle.

Several people sat here every day, and the ground became much smoother.

Yesterday I explained some division methods, involving the average score.

Li Yang thought about it for a while, and first let the clansmen understand the method of division.

The second child, Xia An and the others all remember the sign '÷'.

There is no need to talk about this point.

Simple cognition should be said.

"Let's learn how to divide first. For example, divide 8 taro mangans equally between Xia An and Atao, and divide each of them into four."

"This process of giving them an average score, we can use division arithmetic to express!"

Li Yang emphatically circled the four words 'division counts'.

"That is 8÷2=4!"

The style is still the style of yesterday, only the second child muttered, "Why are the taro man stems distributed to them again?".

Nobody paid attention to the second child, and Li Yang naturally did not pay any attention to it either.

Listing out the formula, Li Yang didn't ask any questions.

Instead, he said directly: "The number 8, it represents the total number divided evenly, it must be in front of this '÷'!"

"2 means the average score. For example, Xia An and A Tao, if written in numbers, it is 2! Write it after the '÷' sign!"

"What does the equal sign represent? I told you a little bit earlier, so I won't mention it now! The 4 in the back indicates the number of points per share!"

When it comes to the division of preliminary cognition, Li Yang speaks relatively quickly.

"In the multiplication formula, 'x' is read as 'multiply' or 'multiplied by', there is not much difference! But the '÷' sign in the formula, read as 'divide by', remember this!"

Emphasizing the reading method, Li Yang has finished his preliminary understanding of the division method.

"One more point, the average score can be expressed by a division formula, if it is not the average score, use this formula!"

Explaining formulas is naturally used in practice.

After talking about cognition, Li Yang turned his attention to the second child.

"Big brother!"

The second child was a little afraid of Li Yang's eyes, he thought he hadn't done anything wrong.

"Second, you heard about the division just now! How about I ask you a question?"

"You...you say it!"

"I have taro mangans here for 20 yuan. If you share these taro mangans equally between you and Zhu Meng, how much can each of you get?"

"20 yuan taro mangan let me share with Zhu Meng..."

The second child muttered and listed crooked calculations on the ground.

'20'÷'2'=

In the following numbers, the second child was stumped.

The formula is right, but how to calculate the process?

Cognitive division is just cognition and will not be used.

The second child muttered, thinking silently in his heart, Zhu Meng and I, how many mangans can there be 20?

Seems to be?

The second child showed excitement on his face.

"Brother, I got it! It's 10!"

After the equal sign, the second child writes down the number '10'.

The corner of Li Yang's mouth formed a smile.

"If it's 220 taro stems, how about giving them to you and Zhu Meng?"

The second child was dumbfounded.

He said nonchalantly: "Brother, this... this is too much, Zhu Meng and I can't finish it!"

"I didn't let you eat, I just let you count! Can you still count?"

So many, how to count?

The second child is worried.

"Can you figure it out?"

Including Ah Xi, the group shook their heads.

Multi-digit division is involved here.

No it is normal.

It's okay if it's simple, but it's a bit embarrassing if it's more.

In the previous life, when Li Yang was taking exams at school, he encountered some uncomfortable exam questions.

小学时让你算从‘1+2+3+4……+98+99+100=？’。

When you enter middle school, do you think you will be liberated?

The test questions have also been upgraded, unexpected!

Let you count '1+2+3+4...+n=? '.

Li Yang doesn't know how much the actual application is. The test of those questions should not be the actual application, but the IQ memory of the peers, right?

A question, how many people can solve it?

Gathering his thoughts, Li Yang returned to the topic.

For the innate human race, junior high school knowledge belongs to the superclass, but it should be a piece of cake for readers.

Difficult level, always like to put last.

For example, division is slightly more complicated than the previous three operations.

He involves three numbers, 'quotient', 'divisor' and 'divisor'!

The evolution of three numbers will naturally produce many conclusions.

In detail, there is a 'countdown'!

Li Yang thought about it carefully, and felt that he was too optimistic after finishing what he said in the morning?

He does not teach for other religions, but for the sake of his tribe.

If one of the second child, Xia An, and the others couldn't understand, he would explain it in detail.

For Li Yang at present, there is not much time cost!

It's impossible for the clansmen to fly into the sky all at once, so take your time, it's useless for him to be anxious!

The rest of the saints have not yet been completed, and it took many years for the development of the sainted human race to attract the attention of the two clans of Lich.

But now, Li Yang doesn't think that the lich and demon races are focusing on their human race.

Let the clansmen eat and put on their coats first, and then talk about other things.
