Furiously Retired His Fiancee at the Beginning and Became the Villain of Destiny

Not only Tang Wan but even the classmates around him also voiced doubts, and no one even looked down on Zhang Fan.

For them, for people with Zhang Fan's identity, it is more of a sense of distance and fear, the so-called awe, or even respect that all stems from instinctive fear.

"I'm so ridiculous, I didn't expect that Young Master Zhang would really agree to compare mathematics with the four-eyed frog!"

"It is estimated that Zhang Dashao still doesn't know the four-eyed frog, he won the first prize in the national competition in mathematics!"

"This wave, this wave is called self-unlucky, this time Young Master Zhang is going to be embarrassed, then we have to bear with it, don't laugh too loudly, it will blow his self-esteem!"

"What are you afraid of? Zhang Dashao said it a long time ago. The rich second generation who won't use our status to suppress us will always speak the same thing. When the time comes, I must laugh at him fiercely and let him lose his face!"

"That's right, this classmate is right. Then I will laugh at Master Zhang severely, let him know what it means to fall from the high clouds to the bottom!"

"Count me, hahahaha!"

…

All of a sudden, the surrounding students sneered and questioned, but Zhang Fan didn't put these people in his eyes and ignored them.

As for Tang Wan, who also heard the ridicule around her, she continued to question Zhang Fan worriedly.

Faced with Tang Wan's worry, Zhang Fan smiled lightly and waved his hand casually.

"Don't worry, I am still very confident in myself in terms of mathematics. With this kind of stuff, I can hang him up and hit him with one hand!"

Seeing Zhang Fan's confident appearance, the sugar pill did not continue to ask more, because he knew that Zhang Fan said yes, that is really possible.

Because in Tang Wan's eyes, Zhang is such a man full of mystery.

Strong and confident.

Soon the four-eyed frog boy wrote the math problem he wanted Zhang Fan to solve on the blackboard!

[It takes 25 seconds for a train to pass through a 250-meter-long tunnel and 23 seconds to pass a 210-meter-long tunnel. If the train meets another train with a length of 150 meters and a speed of 72 kilometers per hour, it will take a few minutes for the train to pass by in the wrong direction?]

Looking at the title on the blackboard, everyone in the classroom let out exclamation sounds.

"My God, it is actually the legendary Olympiad!"

"It's too good, I can't figure out the principles of Olympiad at all. I didn't expect that the four-eyed frog would just be an Olympiad day problem!"

"Yeah, just looking at the title can't understand what he is trying to express. In short, it looks good!"

"This wave, this wave, I guess Zhang Dashao can't solve this kind of problem at all, normal people will not study him!"

…

For a while, everyone in the classroom began to question Zhang Fan's ability.

Even the four-eyed frog on the side was very disdainful, he threw the chalk away, and then said to Zhang Fan extremely arrogantly.

"It's you Zhang Dashao, come up and solve my problem, if you can't solve it, you apologize to all of us now, and we can forgive you too!"

The four-eyed frog boy looks like I'm doing it for your own good to avoid your embarrassment on stage. People look at him and want to beat him very much.

However, looking at such a simple subject, Zhang Fan smiled disdainfully.

"With such a simple topic, are you insulting my IQ? Let alone me, even the readers of this book can understand it!"

Zhang Fan quickly stepped forward, picked up the white chalk brush in the chalk box and started to write.

[The train passing through the tunnel refers to the time when the train enters the tunnel from the front of the train to the end of the train leaves the tunnel. Therefore, the distance traveled by the train in this process is equal to the length of the train plus the length of the tunnel.

First of all, we can first find the speed of the train (250-210)÷(25-23)=20 (msec), since we already know that the distance is equal to the length of the train plus the length of the tunnel,

Then the length of this train is 20×25-250=250 (meters), here we have a unit conversion, 72 kilometers into meters: 72000÷3600=20 (meters)

So the wrong time for the two cars is (210+250)÷(20+20)=400÷40=10(sec)]

"So the missed time of the two cars is 10 seconds!"

Zhang Fan threw the chalk casually, turned around, and looked at the four-eyed frog in front of him with a disdainful face, as if mocking his question for being so simple.

"What, it's impossible!"

Seeing that Zhang Fan really solved his problem, the four-eyed frog in front of him made an incredulous voice.

Even the students around him were shocked.

"My God, Young Master Zhang actually solved the problem of the four-eyed frog, it's over!"

"Damn it, why does Zhang Dashao actually know the Olympiad? It doesn't make sense at all. Isn't he a family member? There is no reason to need to learn this kind of thing!"

"You said it's you, I don't even think about it. Shouldn't this kind of rich second-generation young man start learning how to run a family business early? Why did you learn this kind of learning without social practice help, seemingly meaningless? Where's the Olympiad?"

…

All of a sudden, the whole classroom was wailing.

Obviously they were completely shocked by Zhang Fan's operation.

Their small brains are so small that they can't think of why they want to break their heads.

The four-eyed frog on the podium, although trembling slightly at the moment, he quickly calmed down because he has not completely lost the duel yet.

Yes, now it's just sister Zhang Fan who has his problem. If she can solve Zhang Fan's problem by herself, then this round will be considered a tie!

I haven't lost yet, it's not the time to despair!

Sure enough, the four-eyed frog boy who had regained his composure regained his self-confidence. He looked at Zhang Fan calmly and said slowly.

"Come on, Master Zhang's turn is yours!"

Looking at the confident and indifferent four-eyed frog boy, Zhang Fan picked up the blackboard eraser and silently erased the scribbled problem in front of him, and then began to write a math problem that he had prepared for him.

[There are 3 people going to stay, 30 yuan a night.

Each of the three paid 10 yuan to make up to 30 yuan and gave it to the boss. Later, the boss said that today's discount is only 25 yuan.

He took out 5 yuan and ordered the waiter to return it to them, and the waiter secretly hid the 2 yuan.

Then.

The remaining 3 yuan was divided among the three people, each of which was allocated 1 yuan.

In this way, each person paid 10 yuan at the beginning, and now returns 1 yuan, which is 10-1=9.

Each person only spent 9 yuan, 3 people 9 yuan each, 3X9 = 27 yuan + 2 yuan hidden by the waiter = 29 yuan.

Where did the other dollar go? ? ? 】

After writing the question, Zhang Fan also learned the appearance of a four-eyed frog, throwing the chalk casually, and said to him.

In the meantime, Zhang Fan did not forget to show a mocking look in his condescending manner.

"Come on, it's time for you to solve the problem!"
