While everyone at the scene was stunned, Su Huai showed a playful smile at this time, and asked in a provocative tone:

"Director Yi, aren't we two wins in three games?"

Just now you slandered me for cheating, it was a coincidence, all kinds of dirty water splashed up, now I will give you another chance, come on, keep going.

Director Yi reacted, he didn't know that Su Huai was ridiculing him, so he gritted his teeth and said in a low voice: "35687929 divide by 4578!"

The Chinese audience in front of the TV was a little angry when they heard the title.

Su Huai said that it was multiplication and division between four digits, but this topic was obviously inexhaustible, and Director Yi had made a loophole and vilely increased the difficulty.

At this time, Edogawa also felt a lot of pressure, and had to start picking up a pen and starting to write formulas.

It's a lot harder than multiplication.

It was indeed difficult, resulting in Su Huai taking 5 seconds this time, more than double the time just now, but he still got the answer before most people finished pressing the calculator.

"The result is 7795.53......"

The pen in Edogawa's hand fell to the ground with a "bang", and he rolled for a second before he heard the calculator from the Institute of Mathematics say in a trembling voice:

"The correct result is 7795·5283967......"

Although it was only accurate to two decimal places, everyone was so shocked that they almost fell off the bench to the ground.

At this time, even the detective master Doyle couldn't help but look at Su Huai, gasped, and thought: God...... Is this strange abacus really so magical?

If there were still doubts just now, Su Shengren memorized the answer in advance, so he could calculate so quickly.

Then this time, there really is no reason to say that he cheats.

After all, Director Yi made the question on the spot, and the people next to him didn't calculate it with a calculator, so Su Huai reported the result......

It's faster than even a calculator, how can this say that he cheats!?

When Su Huai took out this abacus just now, many people laughed out loud in their hearts, thinking that this thing was just a counting tool.

I didn't expect it to be so fast and so accurate......

If they hadn't seen with their own eyes how Su Huai had solved two problems in a row, they would never have believed that someone in the world could use this kind of thing to calculate such a complex operation with a few crackles.

You must know that Su Huai's comparison is the world speed calculation champion Edogawa!

But in fact, Su Huai not only won Edogawa, but even the calculator was not as fast as him!

The detective fans present only felt that their life values had been subverted by everything that happened in front of them.

The signature smile on Su Huai's face, in order to shock everyone, raised his hand and raised the abacus, explaining:

"The mantra of this abacus division is, one return is like one into one, one into ten, two into five, two into fourteen, twenty-six into thirty-eight, thirty-one thirty-one, three into sixteen, twenty-nine into thirty, forty-one, twenty-two, and twenty-two, and forty-one, twenty-two, and twenty-two, and one for four, and fourteen, and twenty-twenty, and five for one, and five into ten......."

In fact, no one understands this mantra, but it is not meaningless, because this is the show, and the video will be preserved forever for those who are interested to verify.

This mantra will also continue to be watched and studied in the future, and the details of it will become part of Su Shengren's magnificent and legendary life.

The host, Kojima, couldn't help but stammer, and asked Ibn with his mouth open:

"Yi ...... Director, what do you think of the calculation method of this abacus, such a magical tool, it is really amazing, don't you say?"

Iben's whole brain was still buzzing, this abacus was not magical, it was just a pile of digital registers, and the real magic was the calculation formulas created by the ancient Chinese.

Addition and subtraction are not difficult, but multiplication and division ...... There is probably no primitive digital register in the world that can do such high-digit multiplication and division.

However, Ibn questioned Su Huai for a long time just now, even if he was defeated, it was impossible to sing praises to him, so he could only blush and say recklessly:

"This abacus does have some effect, but this backward tool has limitations after all, addition, subtraction, multiplication and division are all possible, but not square, and Edogawa superintendent's quick calculation can be prescribed...... It can only be said that the ancient Chinese and our modern quick calculation formulas have their own characteristics. ”

When the Chinese audience in front of the TV heard this, they couldn't hear that this Ibn was holding on, and scolded at the TV one after another:

"What kind of expert is this, is there an end?"

"It's not enough to add, subtract, multiply and divide? In ancient times, we didn't engage in scientific research, so why do we need to prescribe a prescription?"

"Until now, don't you admit that the ancient Chinese people had very high mathematical attainments!? It's too shameless. ”

Unexpectedly, in the face of Ibn criticism, Su Huai shook his head:

"Director Yi is a layman, although this abacus is not good at the power of high numbers, the square, but it is not impossible. ”

Hearing this, Ibn shook his whole body...... What do you mean, you can still prescribe a prescription with this abacus!? If you can prescribe a prescription, wouldn't it be true that all the records of the world's quick calculation will be broken?

At this time, Doyle on the side proposed: "Since this is the case, then Mr. Su can't help but play an extra game with Edogawa Superintendent, then open 80315.56." ”

Su Huai only said multiplication and division, and this square operation is strictly not included in the rules, but at this moment, Doyle is suddenly in trouble, just to get back a little face.

At this moment, Edogawa had already reacted, and regardless of whether Su Huai agreed or not, he had already begun to use paper and pen to calculate.

And Ibn didn't move anymore, just stared at Su Huai to see how he reacted, only to see Su Huai smile casually, and gently flicked the abacus with his slender fingers, and the abacus began to move at a high speed and smooth.

This action makes everyone's eyes straighten when they look at it!

It turned out that Su Huai hadn't used all his strength just now, and now he was still speeding up!?

At this time, Su Huai also deliberately showed it, deliberately making the sound of the abacus louder, and everyone saw that the abacus was constantly moving, and their eyes couldn't keep up at all.

At this time, I only heard Su Huai's voice coming slowly:

First of all, we must use the abacus to carry out the first step of the open square operation on 80315.56, and divide the given number into segments: single digits, ten digits (if any) to make a "segment"; 80315.56 is divided into four sections: 8, 03, 15, 56.......

This time Su Huai intended to show off, explaining and planning at the same time, so this time the calculator finally won Su Huai's abacus, but no one cared, everyone was waiting to see if Su Huai could use the abacus to solve this square operation.
