Start by traveling through the Widow's Village

Xiao Yuan didn't know where to take out a copper plate, put it in his hand, and said to everyone in the hall with a smile: "In fact, the calculation method of this question is very simple, one copper plate a day, a hundred days is a hundred copper plates, if you want to calculate how much in total, you have to add from one to a hundred, you may want to understand?"

Everyone also nodded, up to this point, they could all know, and it was precisely because of this that they felt that Xiao Yuan was suspected of deliberately delaying time, after all, from one to hundred, it was not possible to calculate it in a while.

Seeing everyone nodding, Xiao Yuan continued: "Didn't you find out... Is there a pattern in this? Xiao

Yuan's words fell, and everyone was stunned, regular? What are the rules? Why didn't they find out?

Huang Yunshuang, Li Changfeng, and those arithmetic students from the Hanlin Academy had already begun to lower their heads and think, while Xia Houlin and Mu Changdong, a strong man from the Northern Youguo, were slightly brightened in front of them.

They knew there must be something in it, but they didn't think about it for a while.

"Why don't you try to connect these numbers end-to-end, such as adding one to a hundred, how much do you get? True, exactly one hundred and one, then how much is two plus ninety-nine? Is it also one hundred and one? So how many such arrays are there? Half of a hundred, exactly fifty sets ~ so that we can get fifty sets of one hundred and one! The entire hall was extremely quiet, only Xiao Yuan was there talking, looking like a gentleman who was teaching everyone in the hall.

And Xia Houlin and Mu Changdong were already relieved when Xiao Yuan said the sum of the beginning and end, Xiao Yuan had already said the law, that is to say, this problem is indeed an arithmetic problem, but they have not solved it.

"But fifty groups of one hundred and one is not so good to calculate!" At this time, a general asked.

Xiao Yuan smiled and said: "That's right, for you, the sum of fifty groups of one hundred and one is still not good, but it doesn't matter, what I just said is my algorithm, as for you, I can teach you a simpler way!" "

Huh? Is there an easier way? When everyone heard this, they all looked at Xiao Yuan, wanting to know how it could be simpler, and even Xia Houlin and Mu Changdong looked expectant.

"First of all, add one to a hundred, and you get one hundred and one, because it is not a whole number, so you think it is not so good to calculate, since this is the case, then we will find a way to make him a whole number!" Xiao Yuan said with a smile: "Let's take out the whole number one hundred and put it aside, then will the number at the beginning and end become one plus ninety-nine, and get the whole number of one hundred?" In this way, we can get forty-nine groups of one hundred, and the last single one fifty, because the last hundred is taken out by us, so the number is only ninety-nine, and the middle fifty is the extra one!

After Xiao Yuan finished speaking, he paused and did not continue, but let the people in the hall digest it for a while before continuing: "Then forty-nine groups of one hundred, plus the one hundred we took out in advance, is fifty groups of one hundred, fifty hundred don't need me to say how much, right?" Add in the fifty that came out of the final single, and then the result is fifty thousand and fifty! As for the result of the thousand days asked by the county owner, the same calculation is true, but the array has changed from fifty groups to five hundred groups! When

everyone heard this, they suddenly realized, and even many students began to take out paper and pen to experiment, and found that it was really as Xiao Yuan said.

At this point in the competition, there is actually no need to continue the competition, because everyone knows that Xiao Yuan won.

But Yeluyan was unwilling, very unwilling.

"I wonder if the county owner will continue to compete?" Xiao Yuan smiled lightly and said, "According to the regulations, I have already won!"

Mu Changdong sighed, his mouth moved, but he didn't speak, he wanted to admit defeat, although Xiao Yuan only came up with one question, but he had already seen the gap between himself and Xiao Yuan, and it was no longer meaningful to continue to compete.

But before the Lord of Yelu County spoke, he did not dare to speak.

"Little sister, forget it, we lost!" Looking at Yeluyan's heaving chest, Yeluyan actually knew that his little sister was afraid that he was a little unconvinced, and quickly whispered comfort.

"Forget it? Brother Wang, we have been planning for so long, so forget it? I'm not willing! Sure enough, Ye Luyan gritted his teeth and replied.

"But... How else do you compare? Let's not say whether Daxia will agree or not, we already have nothing to try! Jeruda said helplessly.

"I'm going to compete with him in poetry again, and this time I don't believe I'm going to lose!" Ye Luyan said stubbornly.

But Yelu frowned and said, "Nonsense, can't you see Xiao Yuan's achievements in poetry?" We were prepared and defeated before, do you think the result of another challenge will be better?

"Then I'll ride and shoot with him!" Suddenly, Ye Luyan's eyes lit up and said, "He is a person who does not understand martial arts, and he must not be able to compare with me!" When

Yelu heard this, he hesitated, indeed, as they grew up on horseback since they were children, riding and shooting were originally stronger than the Nanren, and Xiao Yuan did not seem to know martial arts.

"But the other party may not agree!" In the end, Jerry shook his head, but his tone had softened a lot.

"Hmph~ I'll make him promise!" Ye Luyan seemed very confident and could get Xiao Yuan to agree to the competition.

It's just that Yeluyan is still a little uneasy, but he can't help Yeluyan, so he has to stand on the side, intending to wait and see.

Over here, Daxia was already planning to celebrate the victory of the competition, and Xiao Yuan had already returned to Mo Wentian from the center of the hall.

"Very good!" Mo Wentian gave a thumbs up and said.

Xiao Yuan arched his hand and said modestly: "Fluke, fluke!"

At this time, he also saw Qin Yuncai sitting on the side, so he quickly stepped forward and asked, "Is the second sister-in-law seriously injured?"

"No problem, just rest for a while, today Xiao Gongzi really shows his might, even if it is just watching the battle, it makes people's blood boil!" Qin Yuncai said with a smile.

Xiao Yuan smiled a little coyly and said, "It's just a coincidence!"

"Okay, go back and let the back kitchen get more dishes, celebrate well, and come back to eat together in the evening!" Mo Wentian said with a smile on his face.

"Good!" Qin Yuncai replied with a smile.

At this time, Sun Wenshan and Huang Qiaoyan and Wei Ziwu had also finished and reported the final results to Tang Jiemin, and finally Huang Qiaoyan announced the final results of this competition.

"By the way, Guogong, what is the stake for this competition?" Xiao Yuan suddenly turned his head sideways and asked.

Now that the competition was over, he remembered that he still didn't know what the stakes of this competition were.
