After talking about the three algorithms of addition, subtraction and multiplication, Huang Jiangguan really assigned ten questions to all the craftsmen for them to do.

They had to write down the answers and turn them in on a wooden board with their number plate number, corresponding to each person's name.

This level of question can be done with your eyes closed, and the answer is already available the moment you see the question.

But instead of submitting his answer board right away, he stared at it and thought about it for a long time.

Before he understood what the imperial court wanted to do, he didn't want to expose himself too much, after all, there must be a reason why Lian Tianqing let him serve under a pseudonym.

The next moment, the two of them stood up at the same time, holding the answer board in their hands, obviously finished.

They got up exactly the same time, as if they had discussed it, and as soon as they stood up, they found each other and looked at each other in unison.

These two people are Jiang Wangfeng and Xu Jueming, the two had a small conflict the day before yesterday, and they bumped into each other again today.

"I'm done. The two turned back at the same time and said in unison.

The movement of the two caused many people to raise their heads and look shocked.

"So fast!" someone whispered.

"I'm not done yet!" said another.

"It's over, I just memorized the multiplication table, and I was going to do it upside down, but I forgot about it!" another person whispered.

"Silence!"

The craftsman shouted and looked around, "The others continue to answer the questions, and they don't need to make a sound for a while, just hand over the answer board!"

Jiang Wangfeng and Xu Jueming were silent at the same time, and walked over quickly to hand in the board, the distance between the two of them was the same as that of the craftsman, and the speed of walking over was the same, and the board snapped and collided with each other in the craftsman's hand.

The two looked at each other again, sparks flying in their eyes.

In this posture, if the two of them are rashly separated, no one will agree.

Huang Jiangguan thought about it, and put the two question boards, one left and one right, on the ground on both sides, and he couldn't tell who came first and who came second.

The third person to "hand in the papers" is Xu San, and the fourth is Xu Xihuai, both of whom also played well the day before yesterday.

Xu Wen waited for another person to hand in his question board, and the results were not bad, but they were not too conspicuous.

Of course, after the day before yesterday, he is already conspicuous enough.

On this day, Xu asked them six people in a shed, three of them ranked in the top five, two did not enter the top 30, and only Tian Jifeng barely squeezed in with 28.

"You can, seven out of ten questions are right!

After going back to the shack, Sun Laosi said with Tian Jifeng in his armpit.

"Bah, Meng Nengmeng is in the top thirty, you give me one!" Tian Jifeng spat at him.

"The first six questions are all right, and the last four questions are only one right. Xu Wen is looking at Tian Jifeng's specific achievements.

"I don't have a good memory. I'm the worst at carrying things, and I always have. I made the first six questions in a while, and I pondered the latter for a long time. Tian Jifeng broke free from Sun Laosi and touched his braincase, a little embarrassed.

"How long have you been working on these six questions?" asked Xu Wen.

"It's pretty fast, basically the answer is written when the question comes out. Tian Jifeng said.

"Then I will come up with a few more questions, you can try?" Xu asked again.

"Okay. Tian Jifeng replied briskly.

“1571+236。 Xu Wen casually asked a question, and the answer had already appeared in his mind almost as soon as he said it.

“1807。 Tian Jifeng was a little slower than Xu Qian, but he gave the answer in less than five breaths.

“2547+2184。 Xu asked again and again.

“4731。 "It's five breaths again, Tian Jifeng gave the answer again, and it was also correct.

In this way, Xu asked questions non-stop, and Tian Jifeng kept answering. Xu asked questions in a similar way to the Huang Jiangguan, adding a single digit each time, and so on.

Tian Jifeng's speed of answering has always been about the same, around five breaths, not too fast, but it is by no means slow.

The most important thing is that the number of digits has been added, and the information that needs to be processed is relatively more and more, but the answers he gives have been very accurate and there are no mistakes at all!

When Xu asked the question, Jiang Wangfeng and Xu San also kept calculating, their expressions were calm at first, and the more they went to the back, the more surprised they became. Jiang Wangfeng is okay, Xu San's speed is gradually not as good as Tian Jifeng.

And Sun Laosi and Chen Wannian looked confused, their heads kept throwing over, throwing them over, and finally stared at Tian Jifeng, as if they didn't know this person.

They met by chance on the way to sign up for service before, and they didn't know that Tian Jifeng still had this hand!

Xu Wen's two-by-two summed up to report five digits, then stopped, and began to become the sum of three three-digit numbers.

Tian Jifeng was a little slower, but he was still very correct quickly, and then there was another wave of questions and answers, and finally Xu asked: "What is the value of seven plus seven plus seven?"

"Twenty-eight!" Tian Jifeng was already very nervous, but when he suddenly encountered a simple question, he suddenly relaxed and opened his mouth to answer.

"What is seven times four?" Xu asked again and again.

Tian Jifeng was stunned for a moment, then laughed, and replied with relief: "Twenty-eight!"

He didn't have much education, and when Huang Jiangguan explained before, he was a little confused about the definition of multiplication, and then Xu Wen explained in a different way, and he suddenly understood it.

This time, as if he had opened a certain trick of Tian Jifeng, he would suddenly memorize the ninety-nine multiplication table.

No, it's not called memorization, but he suddenly understands that numbers should be, or in what way, can be organized.

"It's a bit powerful......" Jiang Wangfeng looked at Xu and asked.

"It's not me who's good, it's him. Xu Wen looked at Tian Jifeng and said.

Some people are born with a talent for mathematics and are particularly sensitive to numbers.

In the five thousand years of China, will there be fewer such people?

Of course not.

Mathematicians are relatively few and far between, and it's just that there are not enough opportunities to be discovered.

Even so, there are characters like Liu Hui, Jia Xian, and Shen Kuo, and the ninety-nine multiplication table has been summarized and sorted out more than 2,000 years ago.

The world doesn't know what the future will look like for people like Tian Jifeng to have more opportunities?

Xu Wen was really curious.

"Brother Fourteen, you can also help me see what I'm good at!"

Although Xu Wen said that this was Tian Jifeng's ability, he was awesome at the slightest bit of Tian Jifeng, which was a fact that Sun Shishi and Chen Wannian saw. The two of them were itching, obviously older than Xu Wen, but they even called out their brother with shy faces.

"Okay, I'll try. ”

No matter what direction you take, everyone has something they are good at, that's for sure.

Combining the two eras, Xu Wen has seen more than them, and he is also idle when he is idle, so it doesn't hurt to help take a look.

He thought about it for a while, came up with a comprehensive questionnaire for them to do, and was a little surprised when he finally looked at the results.

"How is the location of the general service arranged, is it completely random?" he couldn't help but ask Jiang Wangfeng.

"I really don't know about this......" Jiang Wangfeng shook his head.

Xu Wen fell into deep thought.

On the fourth day of going to the Western Desert, after a hard day of marching, the Huang Jiangguan gathered them together again.

"Today we continue the game. By the way, starting today, the game will be played in groups every day from now on, and the groups will advance and retreat together. Today I give you a chance to regroup, and you can reconsider. ”
