"Unknown conditions are conditions that we do not know, that is, conditions that the questioner asks us to find. We need to deduce unknown conditions through known conditions!"

"So, after knowing these two points!"

"We're about to start solving problems!"

"When solving problems, there are many different methods, the two simplest methods, the first one, the hypothesis method!"

"The second type is the method of counter-proof!"

...

Fang Bai explained these two simplest mathematical methods in an easy-to-understand manner. Based on his initial contact with this young man, he could roughly determine that this young man's mathematical level should be around the fifth grade of elementary school!

"Assumption method...the method of inverse evidence? Why didn't I expect that there is such a great method in mathematics?"

"This... is simply a milestone theory in the mathematics world, and it is simply a master-level theory!"

Just after Fang Bai finished talking about these two methods.

A very marvelous praise suddenly appeared behind him.

When the two turned around, they saw an old Mediterranean man with a look of exclamation, as if he was crazy, and he was muttering something.

In the eyes of young people, assumption method and counter-proof method may be just two methods used to solve problems.

But for this Mediterranean old man who has been immersed in mathematics for many years, his understanding of mathematics has reached...u...at least the level of the second grade of junior high school!

In the eyes of the old Mediterranean, these two methods are no different from the "Yi Jin Jing" and "Eighteen Palms of the Dragon Subduing" in martial arts novels!

Countless problems left in mathematics and unsolved problems seem to have thoughts at this moment.

"That's great, it's simply amazing. Which master's research is this? No, the master definitely doesn't know anything about it. This must be the god of mathematics!" The old Mediterranean man's eyes lit up and his breathing was rapid with excitement.

"Teacher, tutor?!"

Seeing his mentor's appearance, the young man hurried over and patted his mentor's back in a hurry.

"Young man, young man, can you tell me in detail about the two methods you just now? I... that... I still haven't understood some of them!" The old Mediterranean man looked up to Fang Bai's side with a thick face.

"this……"

Faced with an old man who is almost the same age as his grandfather, Fang Bai is really embarrassed. This feeling is like when you are playing a game, an old man suddenly stands behind you and then concentrates on watching you operate...

The atmosphere was a bit awkward.

Are you showing off or not?

If you are a girl, let’s not say much, Tianxiu will start to show off! Even if the record is already 0-22-0, it will not stop my heart that wants to show off.

But it's an old man...

This is a ghost, show it to the old man?

After the show, this old man will say to you: "Young man, you know how to play!"

I feel my scalp numb after thinking about it!

Looking at Fang Bai with a difficult face, the old Mediterranean man might also know that he was too presumptuous and that theoretical knowledge like this is basically the secret of various schools of thought.

And I was so arrogant that I wanted others to say everything in my school...

"I'm really sorry, the old man... took the liberty!"

The old Mediterranean man raised his hand apologetically.

"I dare ask, this little brother, which master has your theory passed down? The old man might be lucky enough to visit the master?"

"Ah? Me?"

Fang Bai was a little confused when he woke up.

"My theory... is passed on, inherited from...that, this..."

Fang Bai suddenly narrowed his eyes. There was no Newton Einstein in this world... Since there was no Newton Einstein, it could have Fang Dun, Fang Yinstein!

Fang Bai suddenly sneered in his heart. I was really embarrassed. Big brothers, who told me Fang to travel through time!

Fang Bai suddenly became serious and looked at the old Mediterranean man seriously.

“I have studied these.”

Looking at Fang, who was so shameless, the wicked Miao widened his cat's eyes in shock... Are all the people on earth so shameless?

It sounds like this that you didn’t study it!

"Is it... it's you?"

The old Mediterranean man looked at Fang Bai in disbelief.

The mental activity is a little frequent.

Later, he seemed to have made up some decision, gritted his teeth, and looked at Fang Bai in front of him, perhaps a little difficult to speak, but after thinking for a long time, he spoke: "Little brother, I don't know if you are a disciple, but you still accept disciples?"

"If you don't dislike me, the old man may not worship you and obey your teachings..."

"tutor!"

The young man beside him heard his teacher say this.

I was suddenly at a loss.

And the old Mediterranean man's words also made Fang Bai a little confused.

Brother, someone on our side just wants to pretend to be a pussy, don’t play this for me!

"It cannot be used!"

Fang Bai quickly refused and accepted an old man as his apprentice. Fang Bai felt that he could not accept it, sometimes appropriately pretending to be appropriate, but like this, you would consider accepting someone who can be your grandfather as his apprentice...

Fang Bai felt that he could not accept it.

"Old man, if you want to learn, I can teach you. There is no need to use this method. It's just some mathematical tips, and there is nothing that cannot be passed on."

Fang Bai didn't think that some of the math tips would be so precious. If you just want a student who has received nine years of compulsory education on the earth, they will have nothing to keep secret.

"How did this make..." The old Mediterranean man suddenly felt a little sad.

Fang Bai glanced at the useless cat on his shoulder, then at the old Mediterranean man and the young man beside him.

The old Mediterranean man wore a magic robe unique to the great magician, and the young man also wore a magic robe of the magician, that is to say...

Fang Bai suddenly had an idea.

If you want to survive in this magical world, what do you need first?

All you need is connections, to put it bluntly, it is background.

What is the background? It is your relationship network.

"Old sir, do you think this is OK? You and I become brothers... In this way, you will not feel dissatisfied. That... I... cough cough... what do you think?" Fang Bai said shamelessly.

"So... very good!" Fang Bai's proposal made the old Mediterranean man very moved. In the face of knowledge, the old Mediterranean man originally wanted to give up his face. As long as he could learn knowledge, these were nothing to him.

And now Fang Bai’s current proposal not only retains his face, but also gives him the opportunity to learn knowledge...

Looking at the old Mediterranean man who nodded, Fang Bai knew that he had already embraced a very thick thigh in this world. If nothing unexpected happens, there should be no problem in survival.

And all this has to be thanked to the motherland. If there were no nine years of compulsory education from the motherland... what kind of virtue is someone on our side?!
