How much can I use math after graduating from college?

Push back a few years, or after the "Medical Mathematics" exam in his freshman year, Li Yuanjia has hardly touched this thing again. At this time, when I really began to recall with my heart, I realized that it was so difficult to recall the most basic things.

Let's just talk about those basic mathematical concepts, integers or something, it's naturally no problem, but when Li Yuanjia suddenly remembered rational numbers and irrational numbers, he was suddenly stunned - these two things seem to be very basic concepts, right? But if you think about it, what do they really mean?

After frowning and thinking for a long time, Li Yuanjia could barely think of something, and quickly picked up a pen and wrote it down in the book.

After making a start, the thoughts slowly flowed back.

Anyway, he is also a man who has scored more than 600 points in the college entrance examination, and the sudden pondering at this time really reminded Li Yuanjia of a lot of things, for example, he suddenly remembered the number series, and then remembered the equal difference, equal ratio and equal sum, and quickly wrote it down; For another example, he suddenly remembered to hook three strands, four strings, five, and hurriedly wrote...... Oh, there is no need to write about this, because the ancestors have already figured it out.

But......

Soon raised his eyebrows, Li Yuanjia couldn't help but scratch his head, "The square of the hypotenuse of the right triangle is equal to the sum of the squares of the two right angles, did the ancestors come up with this thing?" Go back and check and don't make jokes......"

After thinking about it for a long time, and after writing down a lot of things, our king finally got irritable and threw the willow charcoal pen to the ground with a bang!

"Sister, I don't forget or something, I want you to have a hair?"

Thinking that the skill he brought through the time crossing did not include the memories of his previous life, and it could only take effect if he looked at it after the time crossing, Li Yuanjia couldn't help but feel the anger in his heart!

Co-authored finally had a golden finger, just to come to ancient times to read those ancient books?

Just preach to such a few students, in fact, Li Yuanjia also wants to get out the "three hundred thousand" and enjoy the taste of being worshiped by Chen Qian, Huang Licheng and others. The problem is that the three-character scripture is better, he can recite "broken machine", and some famous sentences in the back, such as "If you don't teach, your father's fault; If the teaching is not strict, the teacher is lazy" or something, he can also remember some of them every three or five times, but he remembered the surname of the hundred families "Jiang Shen Han Yang", and the thousand-character text only remembers the eight words "Heaven and Earth Xuanhuang, the universe is desolate......

Tell me, what's the use of this?!

"Alas, tragedy, ah......"

Looking up at the sky and sighing, Li Yuanjia's expression at this time was so gloomy.

In a sad mood, he was in no mood to recall any mathematical knowledge, so he simply closed the blank pages of the book where he had written more than a dozen pages, got up and walked out of the study with his hands in his hands.

Anyway, I just want to cultivate a few reliable and loyal account rooms, the requirements are not high, I can use Arabic numerals, know the four operations, and learn what decimal places, positive and negative numbers will learn in the future, and then I can solve a simple equation or something......

Math or something, let it die first!

After walking out of the study angrily, Li Yuanjia felt depressed for a while, so he thought about going to the backyard for a walk - after staying for half a year, after smashing into hundreds of thousands of people and hundreds of days of labor, the backyard of the Luzhou Government Office has changed greatly. According to Li Yuanjia's request, the land became leveled, hundreds of meters of paths were paved with gravel, and many fruit trees were planted in the courtyard in addition to the grape trellises.

Although the fruit trees are still too small, and there is no green at this time, Li Yuanjia will feel more comfortable just walking in the backyard.

"When the weather gets warmer, do you want them to dig a pool of water and come out?"

While secretly thinking about the cost of building a small pond, digging a small river, and building a few rockeries, Li Yuanjia walked to the backyard. It's just that he was halfway through, and he saw Han Shan hurriedly coming over, and after finishing the salute, he hurriedly said: "King, don't ask Chen Lin to see you in Luzhou!" ”

"Chen Lin? What is he doing again? ”

Stopping, Li Yuanjia looked at Han Shan with a puzzled expression.

Since taking up the position of Luzhou Assassin, it is definitely not right to say that Li Yuanjia completely ignores political affairs, after all, as a member of the Tang Dynasty, how can King Yu be a vegetarian? Therefore, every day in the Luzhou Bureau, our king will still go to work, and officials at all levels can just come to find it as long as they have something!

It's one thing to come and find it, and it's another thing to solve the problem.

Anyway, Li Yuanjia's reaction has always been to wave his hand and point out a clear way to those people, such as "go to Chen Beijia and let him help deal with it", or "Go to Wang Changshi and say that I will let him solve it" and the like. So slowly, unless Li Yuanjia has to come forward, or act as a humanoid seal, many officials basically don't come to him.

In fact, in Li Yuanjia's opinion, this is really good.

Everyone no longer has to deal with a fifteen-year-old assassin with an attitude that is respectful on the surface and secretly doesn't know what it is, and he doesn't have to deal with those extremely annoying government affairs that are often very different from his worldview.

However, among all the officials, Chen Lin is obviously an exception.

After other officials knew the attitude of King Yu, they always didn't come if they didn't come, but Chen Lin came to the government office twice in three days to report, and he couldn't wait to ask Li Yuanjia for instructions on everything. Although he stretched out his hand and didn't hit the smiling person, Chen Beijia was respectful every time he came, but after a long time, Li Yuanjia was really a little annoyed by him.

In comparison, his son Chen Zhi is much cuter.

At least half a year to get Li Yuanjia 600 catties of iron, and promised to hand over the remaining 400 catties before the end of March, which really solved the big problem of the palace. You must know that Li Yuanjia still has a lot of ideas to use that thing, and the inventory of the palace is really not much......

"Uh......"

Looking at Li Yuanjia's puzzled look, the corners of Han Shan's mouth twitched, and he replied helplessly: "King, Chen Beijia should have come for the arrangement of the day of the beginning of spring...... Do you want to meet him now? ”

For his own king, Han Shan was also quite helpless.

Even if he understands that sitting in Li Yuanjia's position, it is not necessarily a good thing if he is too diligent in political affairs, and before coming to Luzhou, both Yuwen Zhaoyi and Yuwen Shiji had specially advised, but seeing that the king who was only a teenager was so "decadent", Han Shan still felt quite uncomfortable.

"Lichun? Oh, it turns out that the beginning of spring is coming! ”

After listening to Han Shan's explanation, Li Yuanjia suddenly realized!

But after understanding, what followed was helplessness and troubles - in this festival that the Tang Dynasty attaches great importance to, as the highest local governor, Li Yuanjia, the history of Luzhou, will definitely not be able to escape......
