No wonder the Ministry of Revenue’s calculation efficiency is so low, the main focus is on relying on more than one person.

Xiao Nan also felt a headache and had no idea how to start. Then he looked at Qin Yu, "Brother-in-law, you have the most ideas, you should come up with a way!"

Qin Yu looked at Xiao Nan and pondered: "Do you want to learn something different?"

Xiao Nan was stunned and curiously said, "What's different?"

Qin Yu pondered: "Simple numbers."

"Simple number?"

Xiao Nan looked confused, "Then...what is that?"

Qin Yu had no words, and he wrote down numbers from 1-10 on the paper with a pen.

Xiao Nan looked unclear.

Shen Binglan stood aside and watched, with confusion on her face.

They didn't understand what Qin Yu wrote and what it meant.

Seeing them both looked confused.

Qin Yu explained: "This one corresponds to 1, this two corresponds to 2, and this three corresponds to 3..."

In fact, the simple numbers he mentioned are Arabic numerals.

The advantages of Arabic numerals are self-evident. Only a few numerical symbols can express all natural numbers, and they are concise and clear, simple in calculations and easy to understand.

Listen to Qin Yu's explanation.

Xiao Nan and Shen Binglan gradually understood and were surprised at the same time.

Qin Yu actually created a complete set of numerical symbols in every move?

this......

This is simply a fantasy and horrifying.

"Brother-in-law."

Xiao Nan looked at Qin Yu blankly, "This... are all you just researched?"

Qin Yu said lightly: "What else? Isn't it much easier to use these simple numbers instead of these original numbers and then calculate them? And the accuracy rate is very high."

Listen to Qin Yu's words.

Xiao Nan freed out two lines of numbers, then glanced at the naked eye, and it came out instantly.

The speed is much faster than he can see capital numbers directly.

"What about my god!"

Xiao Nan couldn't help but feel a burst of surprise, "This...it's really much simpler to calculate!"

He really didn't expect that Qin Yu's talent would be displayed wherever he was.

Shen Binglan raised her eyebrows, and she didn't expect that Qin Yu could even come up with such a method of cheating when studying mathematics.

The benefits of simple numbers will be more fully reflected as the calculation volume increases.

Qin Yu said lightly: "We have to replace all these capital numbers with simple numbers."

Xiao Nan looked at the books of the two tables and said in surprise: "This...when will this be replaced?"

Qin Yu pondered: "Sharpening a knife will not delay cutting wood. Even so, our efficiency will be greatly improved."

As he said that, he glanced aside, "If you say this, we don't need to replace it ourselves. Just find two minor officials."

Afterwards, Qin Yu asked Lutai to find two minor officials and then gave them the simple number professor.

After hearing this, the little official felt shocked.

The prince-consort is truly unparalleled in the world and can do something.

Immediately afterwards.

Qin Yu and his friends began to divide the work and cooperate, and the two minor officials replaced the capital number with simple numbers.

Xiao Nan is responsible for oral calculations.

Shen Binglan is responsible for the summary.

Qin Yu is responsible for........ he is responsible for fishing.

There is no way, after all, the numbers developed by Qin Yu have improved the computing efficiency a lot.

He is qualified to fish.
