Two sparrows, as if they were in love.

The male sparrow spoke, "Shall we continue to kiss?" ”

The she-sparrow said, "No...... It's too easy to be blocked by kissing descriptions......"

The male sparrow said, "Yes, you can't describe it from the neck down." ”

The female sparrow continued: "Dead~"

The male sparrow spoke, "Shall we continue to talk?" ”

The female sparrow continued: "Don't, after the founding of the country, it is not allowed to become a sperm. ”

The male sparrow spoke: "Then the stupid × is still looking at us?" ”

The she-sparrow continued: "Don't mind the fools, let's fly away......"

"Chirp~"

"Chirp ~ Chirp"

"Chirp~"

……

It is not clear what the two sparrows are doing, but in his eyes, the existence of the two sparrows is like two special points, of which the one on the left can be regarded as a movable x1 point, and the one on the right can be regarded as a movable y1 point.

Set up two movable x1 and y1 points in the original range.

Set up a binary quadratic equation, so that two completely different answers will be obtained, and the question mentioned is to obtain the maximum area of the interval, so the two answers take the maximum value, so as to obtain the value of x1 and y1, and substitute it into the formula to get the answer.

Perfect~

That's great!

What a genius to yourself.

Consumes time.

Fang Chao glanced at the time.

Duration: 56 minutes.

Compared to the previous test paper, although it took ten minutes more, but Fang Chao didn't think it was anything, the difficulty of this test paper was definitely higher than the previous one.

"Mr. Lin is terrible, he must have prepared the easiest test papers for me to answer first, and then the more the exam papers were given to me later, the more difficult the test papers became, this is to slowly destroy my willpower and make me lose confidence in mathematics......"

"But Mr. Lin, you underestimate me too much, don't you? I love to learn, I have an unprecedented passion for mathematics, and in my heart, there is nothing else but to learn mathematics well. ”

"Hmph, let's start the next one, Hubei test paper, let me see what you are, it can be called hell mode, Hubei, I'm coming!"

Fang Chao took a sip of water and put his pen into the test paper.

Lin Haifeng glanced at Fang Chao and was stunned for a moment, fifty-six minutes, this is already a completed one?

Although it is only a test paper, but with the previous test paper as the basis, it is equivalent to two test papers added up to less than two hours, and mental power, the more you use it, the more it consumes, this is not easier than physical work, and a long-term math high-intensity test is easy to make people have mental problems, especially the serious point is that the amount of hair will be less and less.

I don't have much hair on my head.

Fang Chao is not very old, but he can't be bald at this time.

Therefore, in order to take into account the improvement of Fang Chao's mathematical ability, and not to let Fang Chao's spirit be too consumed, he controlled the time to about six hours, such a point in time, which was just enough for people to play freely without excessive mental consumption.

And he expects to have a maximum of four test papers, usually three to the sky.

However, now, before noon, Fang Chao had already completed two test papers.

At this pace, six hours, is this the rhythm of completing six test papers against the sky? Myself...... I don't think I brought that many test papers.

Although there are them in the office, they are all regular test papers, and they are too trivial to deal with Fang Chao, maybe it only takes twenty minutes to solve a test paper, which is too insulting.

"Let me see if the test papers in Hubei can help me trap you for a while!" Lin Haifeng's heart thought viciously, and pinned his hopes on the Hubei test questions.

Twenty minutes later, Fang Chao was still stuck on top of the penultimate multiple-choice question.

"It's so strong! It's hell mode, and it nearly doubles my answering time, but do you think this will stop me? Hahaha, you don't take me seriously too much, I'll kill and kill!! ”

Fang Chao held the decimal system in his left hand and the quadratic function in his right hand, making a bold move, killing this multiple-choice question to the point that blood was splashing, his eyes were full of hideousness, and on top of the entire multiple-choice question were the numbers and English letters that belonged to it after decomposition, and there were some additions, subtractions, multiplication and divisions.

In the end, Fang Chao got this multiple-choice question done.

"No matter how powerful the prey is, it can't escape the cunning hunter after all, hum!"

Fang Chao's face was full of pride, it was not easy to solve this multiple-choice question, he actually delayed it for about ten minutes, but it was still useless, he was killed after ten minutes, he lost his armor and lost his armor, he didn't have any power to parry at all, Fang Chao successfully got the scores of all the multiple-choice questions.

"Hmm, the test papers in Hubei are really a bit perverted...... Are these teachers still human? ”

"Well, there is also Jiangsu's purgatory mode, I haven't been exposed to it yet, but those who make the question must be the Great Demon King......"

"Sprouting and shivering......"

Although he has a system, Fang Chao still knows that there are people outside the world, and there are heavens outside the sky, and these people should not be underestimated.

Some people are born with amazing talents, they can export chapters at the age of three, memorize the teacher's watch at the age of five, do functions at the age of seven, and may be exposed to some quantum mechanics and so on at the age of ten.

Those are the pride of the sky, Fang Chao is of course systematic, but starting from scratch, it is difficult to compare with those great powers, the future learning path is still very long, he needs to continue to sharpen, and finally enter the ranks of geniuses, keep pace with those pride of the sky, and even catch up with them.

This is a long way to go......

But Fang Chao was full of enthusiasm and eager to try.

Immediately after the fill-in-the-blank question, Fang Chao seems to be incarnated as Nezha, with three heads and six arms, one hand can hold a one-dimensional quadratic equation, a binary quadratic equation, and a covariance theorem at the same time, and the other hand holds a quadratic function, a radical identity deformation, a simple enumeration method, and a logical, thinking, and example jumping in his eyes.

Three-headed and six-armed attack.

Combo Skills!

Triple Combo Skills!

Alternate hands! Hot Wheels!

These special skills were controlled by Fang Chao, and they completely showed their abilities beyond their original abilities, and the charm of mathematics lies here.

It's not singular, there can be an infinite number of radicals, algorithms, formulas, etc., in a problem, and these formulas need to be split, decomposed, and finally combined.

The question is dead, but man is alive.

The process of solving problems is also the most attractive part of mathematics, and its charm attracts these people all the time.

Twenty minutes later, Fang Chao killed all of these fill-in-the-blank questions!
