But from one to ninety-nine …
He had never calculated anything like this before.
However, this could indeed be practiced. Who knew when he would be able to use it?
With that thought in mind, Xiong Ye began to count. "1, 2, 3 …"
The Grandpa Priest taught him to count to a hundred, but it was easy for him to make mistakes. He just counted ten by ten, and after counting ten, he put them in a pile. When there were ten small piles, there would be a hundred, and when they were put together, it would be a big pile. Then he would count to the next hundred …
When he finally counted the results, Xiong Ye immediately looked at Zhou Ji. He wanted to tell him his results, but he realized that Zhou Ji had already fallen asleep.
He felt an itch in his heart, but Zhou Ji felt uncomfortable …
Xiong Ye decided to lie on the bed and be self-sufficient. He had always done this in the past. It was only after he became Zhou Ji's partner that Zhou Ji helped him.
Zhou Ji, who hadn't slept: "…"
While he was busy, Xiong Ye saw Zhou Ji open his eyes. He leaned over and kissed him, saying, "Zhou Ji, help me touch it!"
Zhou Ji glanced at him and stretched out his hand. Xiong Ye took the opportunity to hug him, softly humming.
When it was finally over, Xiong Ye was so comfortable that he didn't want to get up, but Zhou Ji pinched his face. "Did you solve the problem I asked you to solve?"
"I calculated it!" Xiong Ye said.
"How much is it?"
Xiong Ye got up from the bed and looked at his pile of sticks. Finally, he said, "It's forty-nine hundred plus forty-nine!"
"Wrong, it should be 49, 100 plus 50." Zhou Ji said. The people in the tribe usually did not come into contact with large numbers, so they would only count to a hundred, and then a few hundred.
Modern people would probably find it troublesome to go through all this trouble, but it was actually quite good for people to be able to smoothly count to one hundred. Zhou Ji remembered that in French, to say ninety-nine, one had to say four twenties plus ten plus nine …
"Why?" Xiong Ye looked at Zhou Ji in confusion. "You counted? I've never seen you count them! "
With such a difficult question, if Zhou Ji had done his calculations, he would have seen a lot of wooden sticks.
"There's no need to count. I'll know the answer just by thinking about it," Zhou Ji said.
How could he know the answer just by thinking about it? Xiong Ye looked at Zhou Ji in shock, "The Beast Deity told you?"
Zhou Ji: "… You think too much."
"Then how did you know?"
"Didn't you separate the piles before? The first pile has one, and the last pile has ninety-nine. Does the two piles add up to a hundred? " Zhou Ji slowly explained the algorithm. His parents placed a lot of importance on education. He was sent to the Mathematical Olympiad class at a very young age. At that time, this kind of question was used to start the Mathematical Olympiad.
Xiong Ye was suddenly enlightened. He rearranged it and found that it was indeed 49 100 plus one 50.
As for why he had miscalculated before, it was probably because he had accidentally lost a piece.
After making the question, Xiong Ye once again said sincerely, "Zhou Ji, you're really too smart!"
"Do you want me to teach you?" Zhou Ji asked.
Xiong Ye replied without hesitation, "Yes! But haven't I already learned it? "He had learned the question, so he could give it to the priest!
"You've only learned one kind of algorithm, so I'll give another question … I caught eight dinosaurs. Of these eight dinosaurs, some have two legs, some have four legs, so there's a total of twenty-two legs. How many of them are two-legged dinosaurs and how many are four-legged dinosaurs?" Zhou Ji said. The classic Mathematical Olympiad question, chicken and rabbit in the same cage, had arrived.
Xiong Ye did not know about Mathematical Olympiad questions. He took out twenty-two wooden sticks and began to arrange them …
This question was directly arranged, but it was not difficult. After giving two legs to each of the eight dinosaurs, he added a few four-legged dinosaurs to the remaining eight dinosaurs.
Xiong Ye was a little pleased, but in the end …
Zhou Ji said, "What if I caught a total of a hundred dinosaurs, a total of three hundred plus twenty legs?"
Xiong Ye had been fiddling with the numbers and felt that it was quite interesting, but after hearing what Zhou Ji said, he was dumbfounded — he had to calculate it this way? And … "You can't catch that many dinosaurs! If you do, you won't be able to catch a single person in our tribe. "
Zhou Ji smiled. "I gave you fish soup. After you drank half a bowl, I filled it up for you. After you drank half a bowl, I filled it up for you again. After you drank half a bowl, I filled it up again. This time, you drank all the fish soup. How many bowls of fish soup did you drink in total?"
Xiong Ye did not understand. "Why do I have to calculate this?"
"A dinosaur can eat half the grass on a grassland in a year. How many years will it take for it to finish eating all the grass?"
"I know this!" Xiong Ye said, "Two years!"
"Wrong!" Zhou Ji said, "Grass will grow. It's impossible to finish eating it in two years."
That was indeed the case! Xiong Ye looked at Zhou Ji in admiration. Zhou Ji was really amazing and smart.
Zhou Ji, who used elementary Mathematical Olympiad and brain teasers to torment primitive people, said, "Come, let me teach you how to calculate. To become a qualified tribe leader, you should learn more things."
"Alright! Do you want the priest to learn as well? " Xiong Ye did not dare to say that he had already learned it, but he thought of the priest — the priest had always liked to learn these things.
"I'm not feeling well. I can't teach too many people," Zhou Ji said.
"Then teach me one!" Xiong Ye said without thinking. He decided to learn it himself and then teach it to the priest.
"Then I'll teach you how to write numbers first," Zhou Ji said.
"Write?" Xiong Ye did not understand.
"Yes, write." Zhou Ji took out a piece of charcoal that he used as a pen and gave it to Xiong Ye. "Use this to write."
Xiong Ye took the piece of charcoal and began to write numbers under Zhou Ji's guidance.
Zhou Ji actually thought of a way to write every number. He was really amazing. He was even more amazing than the priest from before.
Xiong Ye looked at Zhou Ji in admiration as he used his big hand to hold the charcoal and slowly write in the cave.
Zhou Ji said, "The number eight you wrote doesn't look good … I'll hold your hand to write."
"Alright!" Xiong Ye agreed immediately. Then, Zhou Ji held his hand.
His hand was very rough, but Zhou Ji's hand … was really very soft and smooth!
Xiong Ye was a little distracted. Then, he heard Zhou Ji say, "You are not paying attention when writing. I have to give you some punishment."
"What punishment?" Xiong Ye asked.
Zhou Ji used the charcoal to draw a circle on Xiong Ye's face.
Xiong Ye did not understand — this was considered a punishment? It didn't hurt or itch …
Then, a few circles were drawn on his face. Later, even his body was drawn …
Xiong Ye did not feel that there was anything wrong. What Zhou Ji taught him was mostly knowledge that only the Beast Deity knew. In the past, what he learned from the priest was not as good as this. If he did not learn it well, he would be beaten. Now, if he did not learn it well, he would just be drawn circles. What was this?
Xiong Ye studied for the whole afternoon and learned the Arabic numbers from one to nine. He could even count from one to one hundred smoothly.
At this moment, Xiong He's voice sounded. "Time to eat!"
Xiong Ye immediately ran out. "Zhou Ji, I'm going to eat first! I'll come back later to learn! "
Zhou Ji: "…" This guy forgot to wash his face!
Zhou Ji was too lazy to go down and directly lay down.
Xiong Ye was excited when he heard the sound of eating. He indeed forgot the thing on his face. He only remembered it when he was outside.
However, he did not take it seriously. If he forgot, so be it. Drawing something on his face was not a big deal. It did not affect his movements!
However, when the people in the tribe saw him like this, they were shocked. "Xiong Ye, what is that on your face?"
"It's a circle. Zhou Ji drew it for me." Xiong Ye said.
"It's really nice to draw! Xiong Ye, you look especially nice like this! "Xiong Qi praised." Look at this circle. It's so round. Both sides are equally round! "
When Zhou Ji used the charcoal to draw circles for Xiong Ye, he did not draw randomly. He was particular about symmetry. Now that Xiong Ye's face was in circles, he looked especially mysterious!
The priest came over. "Xiong Ye, why did Zhou Ji draw circles for you?" Was this a strange ceremony or a sacrifice?
"Zhou Ji drew it for me when he was teaching me how to count." Xiong Ye originally wanted to say that he did not learn well from Zhou Ji. However, he did not want others to know that he was stupid, so he did not say it.
"Count?" The priest was curious.
"It's just counting." Xiong Ye looked at the priest. "Grandpa Priest, do you know what one plus two plus three equals to ninety-nine?"
"This is a little difficult. I have to calculate it slowly, and I'm afraid I don't have enough wooden sticks." The priest began to look for wooden sticks.
Xiong Ye said, "Actually, it's very simple. This way …" He repeated what Zhou Ji had said.
The priest was instantly shocked. It could be done like this? It was too amazing!
Especially … Xiong Ye actually wrote numbers on the ground!
So numbers could be represented with such symbols? It was indeed much more convenient! He had always used wooden sticks to arrange the numbers. If he wanted to write, he would draw a few wooden sticks … His hands were especially sore from writing.
The priest's expression became excited. He looked at the circles on Xiong Ye's face as if he had seen a pile of treasures.
The priest looked at the circles on Xiong Ye's face with reverence.
Zhou Ji did not want to join the tribes below, so he made some barley porridge for himself. At the same time, he began to miss elephant bird meat.
After eating too much fish every day, he felt that fish did not taste good anymore. He wanted to eat some other meat.
There was nothing much to do today, so Zhou Ji did not use his mental power to observe the situation in the col. It was only when someone climbed to the entrance of his cave that he turned his head and saw the old face of the priest.
The priest grinned at him, revealing his gums that had only a few teeth left. "Zhou Ji, draw a few circles for me too. I also want to learn the knowledge of the Beast God Religion!"
