Chapter 431 - 431: Calculation

Ye Muyu was relieved and nodded. It had been a while since she last saw Old Madam Ye, so she wondered how she was doing.

However, thinking about it, it was not bad. After all, every three or four days, she would help sell pickled cabbages.

“Ah Yu, this calculation of yours…” Chu Heng suddenly asked. His eyes flashed with a deep light, as if he could not understand Ye Muyu’s eyes. The shock in his eyes and the uneasiness hidden in the depths of his heart shocked him greatly.

He had a very serious and cautious expression on his face. Anyone who saw him would not dare to be presumptuous in front of him.

Ye Muyu noted down the last transaction and looked up at him. Her heart skipped a beat when she saw his expression. However, she tried her best to calm down. “What’s wrong?” she asked.

“I’ve never seen this calculation before.” Chu Heng’s eyes were like torches as he stared at her.

Ye Muyu knew that Chu Heng would ask her if she used mental arithmetic, so she quickly calmed down.

It was not that she did not want to use an abacus, but she had never learned it in her previous life, nor had she seen anything related to it. Therefore, she found it troublesome, so she did not use it.

Moreover, she had read from some miscellaneous notes that whether it was the previous dynasty or Great Chu, there were people who knew how to calculate.

She would not be considered strange.

“After I started keeping accounts some time ago, I slowly learned mental arithmetic. Perhaps I’m very good at it…” Ye Muyu was not lying. Even if she said she was someone from the future, would Chu Heng believe her?

If she were to tell her that one of her relatives was someone from the future, he would probably feel a little estranged.

It was better to treat them as people from the same era.

She was not lying. In her previous life, she was indeed an all-rounder in science. In this life, she had the ability to do mental arithmetic. Although most of it was trained by her every time she kept accounts, she still had to have some talent.

“As for the calculation technique, I also read it from ancient books.” Many things could be traced back to ancient times. Ye Muyu was not lying.

“I read it in that book,’Arithmetic.”

“Haven’t you seen it before?” Ye Muyu was also a little surprised. This book was from the study. The books in the study were all Chu Heng’s.

Chu Heng carefully recalled the book, and then remembered that he had just bought it from a merchant. At that time, he had just been reborn. Just as he was about to read it, Tang Rou knocked on the door.

Then, in a fit of anger, he stood up and dropped the book.

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

“I haven’t seen it yet.” Chu Heng shook his head lightly.

Ye Muyu saw that he was not faking it. He really had not read it. She was curious. “Then I’ll go back and read it tonight. There’s a similar calculation technique in that book. I used it based on my own understanding.”

“If you want to learn it, I can teach you.” Ye Muyu recalled that the imperial examinations now tested mathematics. If Chu Heng could learn the arithmetic of Arabic numbers and memorize the multiplication table, it should not be difficult for him to do mental arithmetic.

Chu Heng reached out and rubbed Ye Muyu’s cheeks. He nodded. It seemed like he was really going to learn.

“Okay, call me if you need anything.” Ye Muyu’s bright eyes were clear. After speaking to him, she lowered her head and taught Chu Ziluo how to write the account book.

Chu Heng looked at the girl in front of him, and a touch of warmth flashed in his eyes. He did not intend to take issue with the loopholes in the other party’s words. Who did not have some secrets in their hearts? There was no need to expose them. It was enough to understand each other..
