"Oppa, where are we going?" Jin Xuexuan, who was well-fed, leaned on Li Tianyu's shoulder a little sleepily and asked casually.

"I don't know, but it's certainly not a good place, you just threw the dice, you threw a two, and our horse got to a skull, I guess nothing good will happen."

Li Tianyu's words made Jin Xuexuan, who was originally leaning on Li Tianyu's arm carelessly, excited: "No, do you want us to play in the water again?" ”

"Huh!" Looking at Jin Xuexuan's panicked little appearance, Li Tianyu smiled and touched Jin Xuexuan's little face and said, "Don't worry, even if you play in the water, it will be me and Brother Guangzhu, and you will be fine." ”

Listening to Li Tianyu's words, Jin Xuexuan smiled, hugged Li Tianyu's arm affectionately and said, "I know that OPPA is the best." ”

About fifteen minutes later, Lee Kwang-so, who was driving in front, suddenly said loudly: "Tianyu, Xuexuan, wake up quickly, we have arrived at the mission location." ”

After hearing Li Guangsu's words, Li Tianyu slowly opened his eyes and said, "Ah, I'm sorry brother, I fell asleep, I worked hard for you." ”

"Huh!" As soon as he was thanked by Li Tianyu, Lee Kwang-so immediately smiled and said, "It's okay, it's okay!" ”

The three of them got out of the car and walked to the mission site, which is a water playground, and when they saw Li Tianyu and the three of them coming over, the PD on the side immediately greeted them with a smile and said: "You are finally here, okay, what awaits you next is punishment!" ”

"Punishment?" Li Tianyu and the three of them were stunned, and Jin Xuexuan, who followed behind, immediately asked, "What punishment?" ”

Looking at the three of them, PD smiled evilly: "The name of the punishment is Flying Fish!" One of the three of you answers the question. The other two sat on the Flying Fish, for a limited time. If the person answering the question answers the correct answer to the question, then you are considered to have passed. If you get it wrong, repeat the cycle. ”

"And repeat the cycle!" Lee Kwang-so said speechlessly: "Then what kind of question do you come up with, always give us a hint, we can choose someone to answer the question." ”

"Math!" In the end, PD saw that the three of them were pitiful, so he gave a hint.

As soon as he heard the math, Jin Xuexuan immediately shook his head, while Lee Kwang-so looked at Li Tianyu and said, "Tianyu, this time it's up to you to answer the question, you didn't say math." Are you amazing? ”

After listening to Li Guangzhu's words, Li Tianyu also nodded and said, "Okay, don't worry, I will definitely answer correctly." ”

The three of them nodded to each other, and then, Lee Kwang-so and Kim Seo-hyun prepared to get on the flying fish, and the so-called flying fish punishment was actually Kim Seo-hyun and Lee Kwang-so, lying in an inflatable rubber mat. And then a speedboat goes full throttle, and then because of the speed the inflatable rubber mat floats up, which is terrifying, because it can float up. That's why it's called a flying fish.

Soon after Lee Kwang-so and Kim Seo-hyun were lying down in the rubber mat, they heard Kim Seo-hyun shouting to Lee Tian-woo: "Oppa, you must answer correctly." ”

Look at Kim Seo-hyun. Li Tianyu smiled and said, "Don't worry, mathematics is what I'm good at." I'll get it right. ”

At this time, PD walked out with a smile and said, "I'm going to solve the question." This question can also be answered by the two punished people, and if you answer it correctly, it is considered correct, and this is our benefit to you. ”

"Oh great!" Li Tianyu said with a smile: "In this way, the three of us can answer the question together, so that the chances of winning will be much greater." ”

"Okay, then I'll have a question, you all have to listen well!" After PD finished speaking, he smiled evilly and said, "My math problem is, what is a slight 37 times 98 times 26?" ”

"What?" Li Tianyu and the three of them were stunned.

At this time, the speedboat dragging rubber mats also rushed out at full speed.

And Lee Kwang-so and Kim Seol-hyun didn't have time to question it, they were immediately dragged out, and then a crazy scream rang out.

Listening to the screams of Lee Kwang-so and Kim Seo-hyun, Li Tianyu didn't have time to complain at this time, and immediately began to calculate this math problem silently, Nima's two-digit triple multiplication, how can this be mentally calculated.

But it's not no, if not, then Jin Xuexuan and Li Guangzhu have to fly fish again, just when Li Tianyu was silently calculating, he inadvertently looked forward, and saw Li Guangzhu and Jin Xuexuan's rubber mat floating up violently, which made Li Tianyu immediately surprised: "Wow, it's really a flying fish!" ”

Li Tianyu's surprise made the PD on the side laugh!

Soon the time to answer the question came, and Kim Xuexuan and Lee Kwang-so also came back slowly, and as soon as they came back, Li Tianyu asked loudly: "Xuexuan, are you okay?" ”

"It's okay, oppa, did you answer your question? I didn't want to sit a second time! ”

Looking at the wailing Jin Xuexuan, Li Tianyu laughed.

At this time, Li Guangzhu, who was lying on the rubber mat, also said weakly: "Tianyu, you have to answer correctly, it's terrible!" ”

After Lee Kwang-so finished speaking, PD walked up to Li Tianyu's side and said, "Can Tianyu answer the question?" ”

Looking at PD's evil smile, Li Tianyu said slightly: "Do you think I can't answer?" ”

Li Tianyu's words made the PDs stunned, to be honest, they really thought that Li Tianyu couldn't answer, after all, it was multiplication of two-digit threes, and the time was so short, how to answer!

However, to the surprise of PD, at this time, Li Tianyu said with a smile: "The answer is ninety-four thousand two hundred and seventy-six!" ”

As soon as Li Tianyu finished speaking, PD looked at the correct answer in his hand in surprise, and said in surprise: "Right!" ”

The correct sentence made Lee Kwang-so and Kim Seo-hyun who were lying on the rubber mat immediately scream excitedly, and then quickly got up from the rubber mat and hugged Li Tianyu!

"Genius, genius, Tianyu, you are a mathematical genius!" Lee Kwang-so said happily!

Not only Lee Kwang-so, but Kim Seo-hyun was also very excited: "I have long known that OPPA will be correct, OPPA is a genius!" ”

Then the two hugged Li Tianyu and shouted happily!

However, after a while, it was RM's PD who said blankly: "Tianyu, how did you calculate, how could mental arithmetic be so fast and so accurate?" ”

Looking at the PD Li Tianyu said with a smile: "The main thing is that your problem is very simple, 37 times 98, I will treat 98 as 100, so that 37 times 100 is equal to 3700 minus two 37 is equal to 3626, the front is solved, the back is multiplied by 26, 26 is divided into three parts, two 10 a 6, two 10 is to add a zero after 3626, then add 36260, and then add 6 3626, the result is 94,276!" ”

"Ahh After listening to Li Tianyu's explanation, the PD finally understood that Li Tianyu did not do hard calculations, but found a simpler way to use addition and subtraction.

Just like Gauss, the mathematician, Gauss was a great German mathematician. As a child, he was a smart kid who loved to use his brain.

When I was still in elementary school, a teacher wanted to cure a naughty student in his class, and he came up with a math problem that made the student go from 1+2+3...... Keep adding until 100. He thought that this question would be enough for these students to count for half a day, and he might also get half a day of leisure. To his surprise, it was just a moment later. Little Gauss raised his hand and said he was done. The teacher looked at the answer, 5050, which was completely correct. The teacher was amazed. Ask Gauss Jr. how he calculated it.

Gauss said that he did not add from the beginning to the end, but first added 1 and 100 to get 101, then added 2 and 99 to get 101, and finally 50 and 51 were added to get 101, so that there were 50 101s, and the result was of course 5050. The clever Gauss was praised by his teacher.

And Li Tianyu used a smart method to solve a problem, and his IQ is very high!
