Chapter 149 Teaching
The priest was very studious, and his master also taught him to count from one to one hundred.
Then the priest taught Lang Yi to count from one to one hundred.
At this moment, Chu Ange asked him to add from one to ninety-nine. Although he couldn't calculate it, he could still break off ninety-nine branches.
Only the lazy orcs of the Tengshe Tribe can count only in dozens or tens.
You can’t blame the people of the Tengshe tribe for being stupid... because in the entire White Wolf tribe, only the priest and Lang Yi can count from one to one hundred.
Lang Bai can't count, but she also feels that brother Lang Yi won't be able to figure it out in a short time.
He said, "Brother Lang Yi, I'm going to go collect first. Come back to me when you've finished your calculations."
Lang Yi took the time to reply to her: "Okay, be careful, don't go too far, follow the main group, don't be left alone."
"Got it." Lang Bai said, "Sister, I'll go collect it."
"Go ahead." Chu Ange said.
As time went by, the pile of sticks that Lang Yi broke became larger and larger.
Just when Chu Ange was about to fall asleep, he finally finished piling up the sticks...
Then I heard him start counting: "One, two, three..."
Although Lang Yi had learned to count from one to one hundred, it was easy to make mistakes this way, so he counted in piles of ten, and after counting ten small piles he put them together to make a big pile: "This is one hundred."
Then count to the next hundred...
Chu Ange yawned and waited for him to count slowly.
At the same time, he did not forget to use his mental power to check the situation in the fire pit.
"Sister, I figured it out!" said Lang Yi.
"How much?"
"Forty-nine hundreds plus forty-nine!" said Lang Yi.
Lang Yi had to spend a long time breaking and counting the numbers on an arithmetic problem, and fatigue appeared on his face.
But he still waited expectantly for Chu Ange to praise him.
Unexpectedly, Chu Ange said: "Wrong, it's forty-nine hundreds plus fifty."
People here generally don't come into contact with numbers that are too large, and they can only count up to one hundred. Numbers over one hundred are expressed as several hundreds.
"Wrong?" Lang Yi looked at Chu Ange in confusion: "Why is it wrong? I haven't seen you count!"
Lang Yi used his eyes to look around for wooden sticks. It was such a difficult question. If Sister had calculated it before, she should have seen a lot of wooden sticks around.
"I know the answer just by thinking about it, no need to count." Chu Ange said.
Can you know the answer just by thinking about it? Lang Yi looked at Ange in shock: "Sister, did the Dragon God tell you?"
Ange looked at Long Chen, just in time to see him rolling his eyes speechlessly.
"You think too much. It's not what the Dragon God told me."
"Then how did you know that?"
"Didn't you separate them into piles before counting? The first pile was one, and the last pile was ninety-nine. Do these two piles add up to a hundred sticks?" Chu Ange said.
It turns out that this is how it can be calculated!
Lang Yi suddenly realized what was going on, and he arranged the numbers again, and found that it was indeed forty-nine hundreds plus one fifty.
As for why he had miscalculated before, he thought that it was probably because he accidentally lost one when counting.
After rearranging it, I saved a lot of time and was able to calculate more quickly and accurately.
Lang Yi once again exclaimed sincerely: "Sister, you are so smart!"
Chu Ange smiled. Her math ability was not good enough in modern times, but it was enough to fool a little savage in the world of beasts.
"Do you want me to teach you?" Chu Ange coaxed.
Lang Yi said without thinking: "I do! But haven't I already learned it?"
He even thought that now that he had learned the question, he would give it to the priest later!
"This is just an algorithm. It's called learning it. Let me give you another question... We have eight animals in our farm. Among them are four-legged giant-horned bulls and two-legged fire spirit birds. Their legs add up to a total of twenty-two. How many four-legged giant-horned bulls are there? How many two-legged fire spirit birds?" Chu Ange said.
A classic math problem: chickens and rabbits in the same cage.
Lang Yi didn't know what an Olympiad math problem was, but he thought this one wasn't difficult. He took out twenty-two wooden sticks and started to arrange them...
One side represents the giant-horned bull, and the other side represents the fire bird. Put four wooden sticks on the side of the giant-horned bull, and then put two wooden sticks on the side of the fire bird. Continue until all the sticks in your hands are put down, and then it is out.
Lang Yi was somewhat pleased with himself, but...
Chu Ange said: "What if we raise a total of one hundred giant-horned bulls and fire spirit birds, a total of three hundred plus twenty legs?"
Lang Yi had been playing with math with wooden sticks and thought it was quite interesting, but when Ange asked this question, he was confused - how was this supposed to be calculated?
Besides... "The giant horned bull and the fire bird cannot be raised together, because the fire bird can fly."
Ange smiled and said, "You squeezed milk for Xiaoyu to drink. After she drank half a bowl, you filled her cup. After she drank another half bowl, you filled it up again. After she drank another half bowl, you filled it up again. This time she drank it all. How many bowls of milk did you pour for Xiaoyu in total?"
Lang Yi was confused and didn't understand: "Why do we have to calculate this?"
"People in the tribe go to cut grass to feed the cattle. They can cut half of the grass on the grassland in a year. How many years will it take to cut all the grass on the grassland?"
"I know this!" Lang Yi said: "Two years!"
"Wrong!" Chu Ange said, "The grass will grow. It's impossible to cut it all in two years."
Lang Yi suddenly reacted and realized that it was indeed the case!
I looked at Chu Ange with great admiration. Sister is really amazing and so smart.
It's quite fun to torment the primitive people with elementary school math Olympiads and brain teasers.
Chu Ange said: "Do you want to learn arithmetic from me now? If you want to become a qualified priest, you should learn more and surprise everyone."
Lang Yi admired her very much: "Great! Do you want to let the priests and the children in the tribe learn from her?"
This kind of good thing would be fun if everyone learned it together.
Moreover, it seems that the priest grandfather always likes to learn things.
"I'm pregnant and can't teach too many people." Chu Ange said.
What the priest teaches is so simple, those kids can’t even learn it… They’d better not force themselves to learn it.
"Then just teach me. Once I learn it, I will teach others." Lang Yi said without thinking, and decided to learn it himself and then teach it to the priest.
Chu Ange also thought so. Some knowledge and culture must be passed on so that mankind can continue to move forward.
However, if she were to be a missionary...she would be more suitable to be the kind of person who has to take advantage of others' misfortunes.
Leave the suffering to those who want to make progress.
Gradually, it got dark.
Lang Bai came back with the gathering team and saw Lang Yi still fiddling with the sticks.
I don’t know whether he figured it out or not, no matter what, I closed my eyes and praised: “Brother Lang Yi, you are really amazing.”
Lang Yi: "Sister taught me a lot of interesting things, but I didn't have time to find you."
Lang Bai: "I have always been with the big tribe, there is no danger."
Lang Yi touched Lang Bai's head and comforted her.
