Chapter 140 Sister-in-law has a new invention

He just sensitively felt that Zhu Xuntao's painting method was of great help to craftsmen when they were making things.

"Is it so amazing?"

Xiao Miluo could naturally see a little bit, but his feeling was not as deep as Xiao Jingshen's.

"Third brother, since you are interested, go to learn from sister-in-law."

Xiao Jingshen was tempted but embarrassed:

"Such an amazing technique must not have been shown to others, otherwise, sister-in-law would have been famous long ago."

"If I go to sister-in-law, will it embarrass sister-in-law?"

Xiao Miluo was a pragmatist, and he pulled Xiao Jingshen to Junzhuyuan:

"Whether it will happen or not, you can just ask sister-in-law."

Xiao Miluo did not dare to guarantee that Zhu Xuntao would definitely agree.

But she felt that there was nothing wrong with this, as her sister-in-law was very kind to them.

"Sister-in-law."

When the two came over, Xiao Jingzhan was not there. Only Zhu Xuntao and Qiuyue who was serving him were in the room.

"Come in, what are you doing standing outside, like you're being punished?"

Even though it was her own study, Zhu Xuntao had no intention of avoiding the two of them and continued with her work.

"Thank you, sister-in-law."

"Ah!"

Xiao Jingshen thanked her sincerely, while Xiao Miluo responded comfortably and stepped in.

"Sister-in-law, are you calculating again?"

Zhu Xuntao nodded slightly, without raising her eyes, holding a pen in one hand and dotting with the other hand in a mysterious way,

then quickly wrote something down with the right hand holding the pen.

Seeing Zhu Xuntao like this, Xiao Miluo and Xiao Jingshen were extremely curious, especially Xiao Jingshen.

He felt that his sister-in-law was not only powerful, but also had many more skills and secrets than he had imagined.

Xiao Jingshen could not help but step forward, regardless of the distance, and approached Zhu Xuntao to see what she was writing.

Then he saw with bright eyes that Zhu Xuntao drew many small boxes on the white paper, and

the words she wrote seemed to be classified and filled in each small box in a regular manner.

As for the words in the small boxes, Xiao Jingshen, who was well-read in books and poems, said with shame that he didn't recognize any of them!!!

He had read books for so many years, not to mention that he could recite them by heart, but how could he not know how to read!!!

"Sister-in-law... what are those words you wrote? What do they mean?"

"Also, sister-in-law, I've wanted to ask you for a long time, why can your words be so thin and small, and still be clearly readable?"

"Sister-in-law, aren't you doing some calculations? No, you don't need an abacus?"

Xiao Jingshen kept throwing questions at Zhu Xuntao.

Zhu Xuntao did not make a mistake in her calculations, and every number matched up.

But Xiao Jingshen's questions overwhelmed her, and she almost couldn't answer them.

A person's energy is limited, Zhu Xuntao can only put down the account book and let his brain rest:

"Don't worry, I can't run away."

"What questions do you have? Ask them one by one and I will answer them one by one, okay?"

"So many questions at once, I don't know which one to answer first."

"That's right, third brother, are you stupid?"

"Sister-in-law has worked so hard, don't cause trouble for her."

Xiao Miluo poured a cup of tea for Zhu Xuntao stickily, and imitated Qiuyue, standing behind Zhu Xuntao on the other side.

Qiuyue pouted, is the young lady trying to steal her job?

Xiao Jingshen's mouth stiffened, and he rolled his eyes at Xiao Miluo.

When he was dragged to find his sister-in-law just now, the younger sister didn't say that.

Xiao Miluo covered her mouth and smiled, raising her chin like a bully:

What are you looking at? I have my sister-in-law to support me. Third brother, I am not afraid of you!

After drinking the tea poured by Xiao Miluo, Zhu Xuntao's mind came back to normal and she began to answer Xiao Jingshen's questions:

"First, what I wrote are numbers, that is, 1234. It may be different from your usual writing, but the meaning is the same."

She wrote Arabic numerals.

Deeply influenced by modern education, she can write even one, two, three, and four.

But this way of writing is too troublesome. With so many accounts, she must use the one she is most accustomed to and the most convenient.

"Ah, these twisting numbers are numbers?"

Xiao Miluo opened his mouth wide, unable to believe it.

"Are there, are there numbers like this?"

"Yes."

Zhu Xuntao had a headache.

"It may not be common in the Yong Dynasty, but the writing and language of countries outside the Yong Dynasty are different from ours."

"So these numbers are from outside."

"I have an uncle who likes to travel around the world, and he happened to bring them back to me."

"I was curious, and after learning it, I found it very useful, so I have continued to use it."

[Well, it takes a hundred lies to cover up one lie. ]

[By the way, does the Yong Dynasty exist in a country like Arabia? Can I still call it Arabic numerals? ]

[Xiao Jingshen and Xiao Miluo must not misunderstand, this is my invention, I don't have such a great ability! ! 】

Zhu Xuntao screamed like a woodchuck in her heart when she heard the last sentence.

Otherwise, it would not be enough to show her inner collapse.

Xiao Jingshen and Xiao Miluo looked at each other:

OK, now they know that this number was not invented by sister-in-law, but the writing of a country called Arabic.

Xiao Jingshen thought more than Xiao Miluo.

It was a new number that was independent and had no flaws.

There may not even be an Arab country in this world, but Zhu Xuntao still didn't want to claim this number as his own, and was afraid that others would misunderstand him.

Such a magnanimity is not something that ordinary people can have.

In the same situation, no one can be as selfless as Zhu Xuntao.

The fame and attraction it brings are really too great.

Xiao Jingshen and Xiao Miluo tacitly didn't ask about the origin of the number.

Xiao Jingshen said:

"Sister-in-law, I am particularly interested in this number. Can you teach me?"

Zhu Xuntao secretly breathed a sigh of relief, glad that she escaped a disaster:

"Of course, little sister, you can learn it together. This way of writing is labor-saving and good for being lazy."

Zhu Xuntao only taught the two of them 0 to 9, and then explained the rules.

The two of them quickly mastered the writing of tens, hundreds, and even higher digits.

After they finished, Xiao Miluo was full of praise:

"Third brother, I can write thousands in the time it takes you to write 1. This is so convenient and easy to use."

Xiao Jingshen just stared at the numbers, completely immersed in them.

The two of them were smart and not young anymore, so they learned faster.

After the two of them completely mastered the writing of Arabic numerals, Zhu Xuntao explained the pros and cons to them.

"Besides my way of writing, we also have two other ways of writing, 一 and 一."

"You probably know that other times, it's 一二三四, but important things are written as 一二三四."

Zhu Xuntao said as he wrote, the contrast was obvious,

"You should understand the difference and meaning."

"So 1234 is similar to 一二三四."
