Chapter 431： Arithmetic

Chapter 431 Arithmetic

People like Ye Pozi who don’t have a mule cart at home take the ox cart at the head of the village, so they leave very early every day.

Ye Muyu felt relieved when she heard the words, and nodded. Speaking of which, she hasn't seen Mrs. Ye for a while, and she doesn't know how her life is.

But it's not bad to think about it, after all, every three or four days, I will help sell sauerkraut.

"Ayu, your algorithm..." Chu Heng asked suddenly, with a deep light shining in his eyes, as if he couldn't understand Ye Muyu's eyes. The uneasiness shocked him greatly.

There is a very serious and cautious expression on his face, and people will not dare to be presumptuous in front of him when they see it.

Ye Muyu wrote down the last account before looking up at him. Seeing the other person's expression, she felt a little bit in her heart, but she tried to calm down and asked, "What's wrong?"

"I've never seen this algorithm before." Chu Heng stared at her fixedly.

Ye Muyu knew a long time ago that if she used mental calculations, Chu Heng would ask questions, so she quickly calmed down.

It's not that she doesn't want to use the abacus, but that she hasn't learned it in her previous life, let alone read related things, so it's useless if she finds it troublesome.

Moreover, she also read from some miscellaneous notes that whether it was the former dynasty or the Great Chu, there were people who knew how to do mental arithmetic.

She wouldn't be too surprised.

"After I started keeping accounts a while ago, I gradually learned mental arithmetic. Maybe I am very good at..." Ye Muyu is not telling a lie. In fact, even if she said that she is from the future, can Chu Heng believe it?

If you tell her that a relative next to her is someone who will come from the future, I'm afraid there will be a gap in her heart.

It's better to be a person of the same era.

She is not lying. In her previous life, she was indeed an all-rounder in science. In this life, she has a lot of mental arithmetic skills. Although most of them are trained by her every time she keeps accounts, she still needs some talent.

"As for the algorithm, I also read it from ancient books." There are many things that can be traced in ancient times, and Ye Muyu did not lie.

"That's what it looks like in the "Solutions"."

"Haven't you read it?" Ye Muyu was also a little surprised, this book is in the study, and the books in the study are all Chu Heng's.

Chu Heng carefully recalled this book, and then remembered that he had just bought this book from a foreign businessman. He had just been reborn at that time, and was about to read it when Tang Rou knocked on the door.

Then, in a rage, he stood up and dropped the book.

After that, he seemed to have forgotten the existence of this book.

"I haven't watched it yet." Chu Heng shook his head lightly.

Ye Muyu saw that his expression was not fake, so he really didn't read it, and was a little surprised: "When I go back to read it at night, there is a similar algorithm in that book. I came up with it based on my own understanding."

"If you want to learn my arithmetic, I'll teach you too." Ye Muyu thought that the current imperial examinations also require arithmetic. If Chu Heng can learn the arithmetic of Arabic numerals and memorize the table of multiplication formulas, he should know how to do mental arithmetic. It's not difficult either.

Chu Heng stretched out his hand and rubbed Ye Muyu's cheek, and gave a hum, which shows that he really has to learn.

"Okay, then call me if you need it." Ye Muyu's bright eyes were clean, and after talking to him, he lowered his head and taught Chu Ziluo how to write the account book and so on.

Chu Heng looked at the girl in front of him, and a warm feeling flashed in his eyes. He didn't intend to care about the loopholes in the other party's words. Whoever has no secrets in his heart doesn't need to be exposed, just understand each other.
