"oh?"

Han Zude followed his instructions and found the last page of the chess score, only to find that it was full of words. It was not like the other white sheets of paper which were all filled with chess scores!

"1 means one, 2 means two, 3 means three, 4 means four, 5 means five..."

"...The digit on the left is ten times the digit on the right, and the number on the right is rounded up by one, for example, 11 is one eleven, 12 is one eleven, and so on..."

There were not many words written on that piece of white paper, but Han Zude's eyes became brighter and brighter after reading it all carefully!

"This...what the hell is this?"

Han Zude was fascinated for a moment, because with his eyes it was not difficult to see that these dozens of words contained huge information.

It turns out that in this era, although there has been some progress in counting methods, in fact, it is far from being as simple and convenient as calculations using Arabic numerals in later generations.

When Qin Yong prepared the chess scores for the two little girls Qin'er and Qi'er, in order to save trouble, every move was marked with Arabic numerals. And because Qin Yong was there to guide him personally, so

Although the two little girls Qin'er and Qi'er saw this Arabic numeral for the first time, it actually didn't have much impact on their reading!

But now Han Zude's situation is different, because this time Qin Yong is not willing to teach others how to learn Arabic numerals step by step, so he simply writes down the general meaning of the Arabic numerals with a brush and gives it to Han Zude

Forget it! He just wrote it down, but without his personal guidance, it would be impossible for Han Zude to fully understand the specific counting method of Arabic numerals immediately!

"This Qin Mingheng is simply a genius! How did he come up with such a simple and clear counting method?"

After some more thinking and comparison, Han Zude roughly understood what the Arabic numeral counting method was all about! And the result was that he was completely stunned! Because he suddenly discovered that if he followed Qin Yong's

If we use the above method to count, the process will be a hundred times more convenient! At present, most of the bookkeepers in major restaurants, brothels, firms and other industries in the Zhou Dynasty are likely to be unemployed.

Because no matter who you are, as long as you learn this counting method called Arabic numerals, you can basically perform counting operations easily, and there is no need to ask any accounting clerk!

"If there is any calculation method based on this Arabic numeral, it may be more convenient to promote this Arabic numeral..."

As one of the leaders of the literary world in the south of the Yangtze River, Han Zude thought a lot!

No, he had just realized what the Arabic numeral counting method meant, and he immediately wanted to promote it! However, he felt a little regretful that this so-called Arabic numeral was just a simple counting method.

It’s just a method! If you want to perform operations between numbers, I’m afraid you still have to convert them back to the original numbers before performing operations!

"This way, it's complicated again!" Han Zude sighed in his heart.

It turns out that in this era, the so-called operations between numbers are extremely complicated for ordinary people!

Well, addition and subtraction of small amounts are actually not too difficult. The average small business owner has done a lot of business, so he naturally has a talent for verbal arithmetic! But once larger numbers are involved, or something similar

Only the real accountants can complete operations such as multiplication and division! And it takes an extremely long time! Because all their operations are based on one, two, three, four, and five.

, Lu, Qi, etc., so the efficiency is naturally extremely low!

"Huh? No, in addition to this counting method, this calligraphy style also seems a bit strange? Well, the structure is square and dense, the strokes are light horizontally and heavy vertically, the writing is powerful, round and thick, and the momentum is solemn and majestic! What kind of calligraphy is this?

?" Han Zude looked at the white paper in front of him and fell into deep thought!

"Uncle, that piece of music you taught Lin Dai'er today was so nice?"

On the other side, Qin Yong left the Xiao Qinhuai River and returned directly to the Qin Mansion with the two little girls Qin'er and Qi'er. On the way, Qin'er couldn't help but say.

"Oh? Does it sound good? I thought you wouldn't like it!"

Qin Yong said. Yes, he did have such a worry before coming back, but now that he heard Qin'er say this, he felt relieved!

It turned out that what he just wrote for Lin Daier in "Yixiang Building" was exactly the same song, and it was also a completely modern melody. However, he really didn't know that such a completely modern melody

Will it be accepted in this era? Although in his plan, this piece of music is not actually the focus, but if this piece of music can be accepted by others, then there is no doubt that the final effect will be better!

"How is that possible? By the way, uncle, can you also teach the maids to sing this song?"

Qin'er asked enthusiastically as she walked.

"Oh? You also want to learn? Okay, but this song is not suitable for you to sing. If you have a chance in the future, I will teach you another one..."

Qin Yong said cheerfully. It has been nearly a month since he came to this era, and he has never been able to find anything meaningful to do. Like this, he went out to visit a brothel, and then came back to tease the two youthful invincibles.

The little girls, that was already the most fun thing, so naturally he would not refuse the requests of the two little girls.

"Really? That's great! Thank you, uncle!"
