"Xiuyuan? Xiuyuan?" Dong Shuyu called softly, staring at Zhu Xiuyuan's face with a pair of wonderful eyes, his eyes were very strange.

"Oh, Shuyu, what's wrong?"

"Nothing...since the plan has been made, why don't we give it a try?" Dong Shuyu said slowly.

"good!"

Zhu Xiuyuan sat down in front of Dongmei's desk, spread the pieces of paper with abacus formulas on the table, and then looked at Dong Shuyu...the abacus in his hand.

Dong Shuyu understood immediately, took the abacus in person and handed it to Zhu Xiuyuan.

This time Zhu Xiuyuan resisted looking at Dong Shuyu, including her hands.

After Zhu Xiuyuan laid out the abacus and abacus formula, he glanced around and had a panoramic view of Dong Shuyu, Dong Shuzhen, the four maids of spring, summer, autumn and winter, as well as the two carpenters. At this time, they all gathered around the table without blinking.

Blinking, he stared at Zhu Xiuyuan and the abacus on the table.

"Let's do this. Before we officially start explaining, let's make a comparison first." Zhu Xiuyuan looked around the crowd and said.

"Husband, what's the comparison?" Dong Shuzhen asked curiously.

"To calculate the same account, use an abacus and abacus to calculate at the same time, and see the difference between the abacus and abacus."

"Hey, this is interesting!"

"Uncle, please come and arrange the calculations." Haruyuki took the initiative to take over the task of using the calculations.

"That's fine!" Dong Shuyu nodded calmly, but a strong fire of curiosity was already ignited in her eyes, because after the tea frying incident, Dong Shuyu had already determined that Zhu Xiuyuan was a talented person, which gave her great confidence in the abacus. As for the abacus.

How high your confidence is can be determined by comparing it with calculations.

As for the rest of the people, such as Xia Wu, Qiu Wen, Dong Mei, and the two carpenters, although they did not speak, they were also paying attention to the comparison.

"Uncle, my servant is ready." On the small round table on the other side, Haruyuki was fiddling with the chips and was ready to settle the accounts.

"Okay... Um, Dongmei, please pick out some of the more difficult accounts to calculate." Zhu Xiuyuan looked at Dongmei and ordered.

"Yes, uncle." Dongmei followed her words and found a few accounts that had just been calculated.

The first account is an addition operation, which is very basic, but the number is relatively large. For ordinary people, it is a bit difficult to calculate it using mental arithmetic, so calculation tools must be used.

The first comparison began. Xia Wu circled the small round table and set up a "calculating array". She was relatively short, and sometimes she couldn't reach the calculating array on the opposite side, so she had to circle the small round table and run to the other side... It looked like

A great dancer.

From Zhu Xiuyuan's side, there was a series of crackling sounds.

Everyone present has basically seen how abacus is calculated, but it was the first time to use an abacus to calculate accounts, so everyone was almost staring at Zhu Xiuyuan's movements.

In Dong Shuyu's eyes, Zhu Xiuyuan's fingers were very nimble, like fingers playing with the strings of a piano. He was quickly playing with the beads on the small wooden sticks on the abacus. The speed was fast and rhythmic, not random... Dong Shuyu fell into deep thought.

"I figured it out, the answer is..."

However, Dong Shuyu hadn't pondered for long. This comparison had just begun, and Haruyuki's "calculating array" seemed to have just been put into place... And Zhu Xiuyuan calculated the final answer through abacus?!

As Zhu Xiuyuan said the answer, everyone looked at him, and then at Haruyuki opposite, with shock in their eyes. However, they still had to look at the final results of Haruyuki's calculations, compare the two, and finally look at Dongyue.

Mei's results, if all three results match, it means...

Dong Shuyu obviously couldn't wait any longer. She looked at Dongmei and conveyed a look. Dongmei understood instantly, looked at her lady, and nodded slowly. In fact, when Zhu Xiuyuan just told the calculation result, Dongmei already knew that this

The thing called the abacus is indeed a calculation tool that goes far beyond a calculation tool.

After receiving Dongmei's affirmative look, Dong Shuyu's eyes suddenly lit up, and his eyes fell on the abacus again...

After a long time.

"Uncle, my servant also calculated it, and the result...is the same as uncle's!" Haruyuki said, wiping the sweat from his forehead.

"Wow! This abacus is so powerful!" Dong Shuzhen shouted immediately, looking very excited.

The rest of the people also looked shocked.

"Let's compare again, this time it's a bit more difficult." Zhu Xiuyuan said facing Dongmei.

"Yes, uncle."

Dongmei found a very complicated account this time, including addition, subtraction, multiplication and division. This account had given Dongmei and Haruyue a headache for a long time...

Not surprisingly, Zhu Xiuyuan relied on abacus to win early again. Haruyuki, who used abacus, had just started...

This naturally caused everyone to marvel.

Abacus is indeed a good thing!

Dong Shuyu was the one who recovered from the shock the fastest. She immediately asked for advice on how to use the abacus.

This is the point.

Zhu Xiuyuan glanced at Dong Shuyu approvingly... Damn, I almost fell again...

After adjusting his mentality, Zhu Xiuyuan began to teach the method of using the abacus and the abacus formula on the spot. Dong Shuyu, Chun Xue, and Dong Mei were learning seriously. Dong Shuzhen, Xia Wu, and Qiu Wen, the three masters and servants, were still learning at the beginning.

It was full of interest, and by the end, I was yawning nonstop. The two carpenters were already dizzy and left with an excuse. Before they left, they were asked to do a few more calculations.

…

…

Dong Shuyu, Chunxue, and Dongmei were the three masters and servants. They were very smart and willing to study hard, so it only took them one morning to master all the abacus formulas. They were already able to flexibly fiddle with the abacus.

At noon, Zhu Xiuyuan and others did not return home, so they just had a meal at the tea house.

In the afternoon, Zhu Xiuyuan began to teach them Arabic numerals again, but the name had been changed by Zhu Xiuyuan and is now called "Xiuyuan Numerals".

With the intelligence of Dong Shuyu's three masters and servants, they quickly mastered the Xiuyuan numbers.

Double-entry accounting is not required, but simple, convenient and easy-to-use Arabic numerals are a must.

Then there is the task of teaching the accounting clerk of the tea house how to use the abacus, memorize the abacus formula, etc.

Dong's tea house has an entire accounting room, and their main task is to settle accounts, while Chunxue and Dongmei's main task is to verify the accounts.

The accounting gentlemen in the accounting room were naturally not as smart as Dong Shuyu's three masters and servants. They did not fully master the abacus formula throughout the afternoon, but they also studied hard.

What Zhu Xiuyuan should explain has been explained twice, and the rest is the work of the accounting gentlemen. So Zhu Xiuyuan's task was finally completed and he felt relaxed.

"Xiuyuan, I still have some doubts about the abacus, and I would like to ask for advice again." Seeing that Zhu Xiuyuan was idle, Dong Shuyu immediately found him.

Although this abacus is wonderful, the more Dong Shuyu thought about it, the more incredible it became. How did Xiuyuan come up with such a magical thing? What other abacus formulas, Xiuyuan numbers, etc., the more he thought about it, the more profound it became. It was simply

It can be said to be a miraculous workmanship.

Dong Shuyu thought to herself that if she had done it by herself, she might not even have this idea, let alone compile such a profound abacus formula. The more Dong Shuyu thought about it, the more she felt that Zhu Xiuyuan was unfathomable...
Chapter completed!
