Chapter 742: Arabic numerals

"Brother Yun, what are the little things that turn in these songs that you wrote down on the paper?"
When Feng Yun was observing the growth of the rainbow rice in each paddy field, Feng Bei's curiosity was aroused by the actions recorded in his notebook.
"Yun, I'm also very interested in the questions Beimei asked. What are you remembering?"
Mulanzhi, who was appointed by Fengyun to take care of the rice fields, also showed an expression of interest.
"I am recording the growth of the rainbow rice in each paddy field, so as to find the planting method with the highest yield and the least spring water consumption."
Feng Yun did not hide his intentions, and he would do so in preparation for leaving Lei Ze one day. After thinking about it, he decided to hand over the task of planting rainbow rice to the Baicao tribe in the future.
With the double cold spring, although it has become easier to grow rainbow rice, he will bring back more precious plants in the future, plus the catalyst for ordinary plants. Compared with the novice, he has rich planting experience. The tribe can obviously do better.
In fact, he will appoint Mulanzhi to take care of the paddy fields in order to make preparations in advance to let her be familiar with and understand not only the process of growing rainbow rice, but also the characteristics of Shuang Leng spring water so that she can use it more in the future. Handy.
"That's it."
After hearing this, Feng Bei and Mulanzhi both showed their expressions of sudden realization, but they became curious again immediately: "What do these little things that turn in the song mean, why haven't we seen it before?"
When Fengyun promoted characters, he took into account the acceptance of primitive people and did not teach them more abstract Arabic numerals.
However, this does not mean that he will not teach all the time. He is just going to wait for a while, so that the primitive people have a process of adapting, and then start teaching. After all, the convenience of Arabic numerals is unparalleled, otherwise it will be before he crosses. It won't be used all over the world.
"They actually represent various numbers, from zero, one, three... to nine."
Feng Yun saw that Feng Bei and Mulanzhi glanced at the notebook in his hand and showed strong curiosity. He couldn't help but added: "If you are interested, I can teach them to you. I don't know if you want it or not. ..."
"Yes, yes, I am willing to learn."
Before Feng Yun could finish his words, Feng Bei nodded, "Although these little things turning in the song may seem a little awkward, if they are really like you said, they can represent numbers, and they will be easier to write than the numbers you taught before. less."
"I am willing to learn too."
Mulanzhi also expressed her wishes.
"Since you are all willing to learn, then I will teach you."
Feng Yun was very satisfied with the performance of Feng Bei and Mulanzhi, and decided to teach him. Now the conditions of the rice fields are in a relatively stable state. He no longer needs to stare at all times. He can still spare some time.
However, for the sake of safety, he didn't bring Feng Bei and Mulan Zhi aside to teach, so he started teaching on the ridge.
"Brother Yun, wait a moment. Wait for Sister Lanzhi and I to get out the pen and paper."
Feng Bei hurriedly opened the shoulder bag he carried with him and rummaged in it.
She admires Fengyun very much. She will imitate many things that Fengyun does. Although she basically doesn't use it on weekdays, when she sees Fengyun carrying a notebook and charcoal in her bag, she also gets a set to wear. On the body.
"Sister Laneige, why don't you take out the notebook and charcoal?"
Feng Bei took the notebook and charcoal out of the bottom of the bag and raised his head, only to find that Mulanzhi was still empty.
"I...I didn't prepare."
Mulanzhi showed an embarrassed expression.
"I have an extra set here, so I will give it to you."
Feng Yun sandwiched the notebook and charcoal pens under his arm, opened the bag, took out a new set of notebooks and charcoal pens, and handed them to Mulanzhi.
"Cloud, I..."
Mulanzhi did not immediately reach out to pick it up.
"Take it. There are still too many empty pages in my notebook, and I can't use it all for a while."
Hearing what Feng Yun said, Mulanzhi took the notebook and charcoal from Feng Yun.
At this time, Feng Bei moved her face and looked at the notebook and charcoal in Mulanzhi's hand, showing a pleasing expression: "Sister Lanzhi, shall we change it?"
"Bei, stop making trouble. You have it yourself, why do you want to trade with Girl Laneige?"
Feng Yun some can't stand it anymore.
"It's okay. Mei Mei can do it if she wants to. It's the same anyway."
Mulanzhi handed the notebook and charcoal in her hand to Feng Bei, but when she looked closely, she could find that her eyes showed dissatisfaction. Obviously, what she was thinking in her heart was not what she said.
"Thank you Sister Laneige."
Feng Bei immediately took the notebook and charcoal from Mulanzhi. The action was very fast, which made people think of grabbing. Then he stuffed his set of notebook and charcoal into Mulanzhi's hand, as if she was afraid that she would regret it. .
"Lady Laneige, can you not be used to Bei from now on, otherwise you will spoil her."
Feng Yun, who saw this scene in his eyes, couldn't help but shook his head.
Feng Bei seemed to have gotten what he wanted, and didn't feel any displeasure because of Feng Yun's rhetoric. He just grabbed the notebook and charcoal tightly, as if worried about taking them away.
"Yun, you should hurry up and teach these numbers. We have learned it, and we can afford some for you."
Mulanzhi glanced at the notebook and charcoal in Feng Bei's hand, suppressed the dismay in her heart, raised her head, and looked towards Feng Yun.
"Okay. You are optimistic. This is a zero."
Feng Yun turned the notebook to the last page, drew a circle in the blank space with charcoal, and then handed the notebook to Feng Bei and Mulanzhi for them to see clearly.
"This is zero, it's too simple, it's like you taught before, so many pens."
Feng Bei took the lead in drawing a gourd on his notebook, and also drew a circle. After finishing the drawing, he looked at it and said, his expression faintly revealed a trace of pride, as if he was satisfied with his performance.
When Feng Yun saw Feng Bei also drew a circle in her notebook, she and Feng Bei wrote a few more times to deepen his memory.
After Feng Bei drew a few circles, he showed an impatient expression, and urged: "Brother Yun, you can teach the next number quickly. It's so simple, Mulanzhi and I have learned it a long time ago."
"Okay. This is one."
Fengyun began to teach the numbers below, and in the process, once again showed why Arabic numerals have swept the world.
Although Feng Bei and Mulanzhi had come into contact for the first time, they still learned it in a relatively short time. It was not until Professor Feng Yun and the others used them to combine larger numbers, and the speed slowed down slightly.
