I Created Civilization In Ancient Times

"Hey~~" Li Yan's eyes widened and he took a deep breath.

He was shocked, he was really shocked.

Addition operation.

In the 21st century, even for the illiterate older generation, this is an extremely simple formula. In this ancient era, its difficulty was no less than learning numbers, or even more difficult.

After all, addition and subtraction... In this day and age, not even a concept has been proposed.

but now.

Moo did it.

She pondered blindly for a day by herself, and researched the first addition operation in ancient times.

This achievement is absolutely no less than that of any top mathematician in the 21st century, and it can be compared with Zu Chongzhi, who counted pi to the decimal point.

"Well, I picked up a genius mathematician back?" Li Yan's expression was stunned.

follow closely.

When Li Yan reacted, he immediately raised his head, looked at Mo, and asked suddenly, "What else do you know?

bun:

She looked blank, as if to say: What else can I know? I just discovered these things by accident?

"It seems that only the basic addition operation has been discovered. 39

Li Yan immediately determined that the mathematics level of Mo was equivalent to the "kindergarten and below" level of the 21st century.

"It's an addition.

Li Yan explained to Mo: "Mo, you did a good job. After you have learned numbers, you must learn addition. The function of addition allows us to accumulate things that have been counted at different times to get a 'sum'. That's what you said 1 and 1, become 2,! For example, 1000 potatoes were dug today, and 1000 potatoes were dug tomorrow

That's 2,000 potatoes in two days!"

In terms of teaching, Li Yan is not a top student, so he can only try to explain it as clearly as possible.

Later, when they get used to these things, maybe they will be able to figure it out on their own?

After saying this, Li Yan chuckled lightly when he saw that Mo was thinking with his head lowered. He walked to Mo's side, took the charcoal in Mo's hand, and wrote an addition equation on the slate: 1+1= 2!

Li Yan pointed to the "plus sign" in the middle: "This is a plus sign, which means, 1 plus 1, 1 and 1!"

Li Yan pointed to the "equal sign": "This is an equal sign, which means to become."

"It's the connection! Li Yan looked at the bun: "1 plus 1 equals 2, of course, as you said, 1 and 1 become 2, that's fine!

"1 plus 1 equals 2? Mo lowered her head, and if she had something to do, she read a sentence that she didn't understand.

"Well, do you remember?" Li Yan looked at Mo, and suddenly felt that this girl became more and more pleasing to the eye.

"Remember." Mo raised his head, looked into Li Yan's eyes, and nodded.

Li Yan smiled and subconsciously reached out and touched Mo's hair:

"Just remember, you stand aside first!

Mo's expression froze.

This is the first time Li Yan has treated her like a snail.

This caused a strange emotion to emerge in Mo's heart. She felt that this feeling was so comfortable, so comfortable, so nice!

Standing beside Li Yan for three seconds, Mo didn't react. Then, when Li Yan didn't see it, Mo's face flushed slightly, he stood aside and thought: I still have 26 X's, just When I'm an adult, when...

Li Yan didn't think about it, and he came to kill him once, so that Mo has already started to count his adult days.

When he was thinking wildly in his mind, he used charcoal to write additions within 10 on a slate.

D:1+1=2,1+2=39+9=18!

"All right."

Li Yan suddenly made a sound, awakening the bun who was caught in "Hu Si".

She looked up immediately, and then her expression was stunned.

"Li Yan is amazing. I thought for so long to come up with things that she didn't need to use potatoes to combine. No, they add up...you can write so many additions." Mo looked at Li Yan There was a hint of admiration in her eyes, she thought to herself.

bun. "

"

Li Yan looked at Mo's face and felt a little strange, but he didn't think about it. He pointed to the addition equation on the blackboard and said to Mo, "Come and read it again, and read it according to the method I added you just now. 39

"it is good."

Hearing that Li Yan taught herself these things without waiting for the snail to come back, Mo felt a strange feeling in her heart. She nodded and looked at the addition equations on the slate, and slowly read them out one by one:

"1 plus 1 equals 2!"

"1 plus 2 equals 3!

・・・ Flowers・

"9 plus 8 equals 17!"

"9 plus 9 equals 18!""

Very good, there are so many addition equations, not one of them is wrong, which makes Li Yan very satisfied.

at this time.

"I am back."

Outside, the girl's laughing voice came.

soon.

The wooden door was pushed open, and snail walked in spiritedly. Then, she saw the addition equation on the slate.

Then, the snail was a little flustered.

She is not stupid, how could she not know that Li Yan is clearly trying to teach something new.

And the new stuff, obviously, has to do with numbers, and seems more complicated and harder to learn.

The thought of learning such a difficult thing and facing Li Yan's examination every day made Luo panic.

.00

At this moment, she wanted to go back to the dormitory where those little girls lived.

"Flame~~"

The little girl was a little flustered when she spoke. She looked at Li Yan, forced a smile, pointed to the addition equation above, and asked, "What, what is this? 39

"This is useful stuff!

Li Yan could see that this silly girl wanted to "play truant", he was amused, and he gave Luo a wicked grin.

That night, before 7 o'clock, Li Yan briefly explained to the snail what addition is.

Then.

In a way of giving death orders, he asked Luo and Moquan to memorize these addition equations, and when he returned, he would check their learning.

If two people can recite the addition equation, Li Yan is ready to teach two people real addition.

On the hour in the morning that night.

"Congratulations to the host, the sign-in is successful. The current number of consecutive sign-in days: 56 days!

"Congratulations to the host, you can get random rewards by signing in for 56 consecutive days!

"Congratulations to the host, get a reward: a full set of snake-catching skills!"

"Congratulations to the host, the skills of raising livestock cubs!"

Hearing the reward given by the system this time, Li Yan had a weird expression on his face.

God.

It's these two rewards!
