The wheels of history are rolling, pushing all the big and small people forward, and if anyone is ready to resist, then congratulations, it will soon turn into meat scraps. Pen "Fun" Pavilion www.biquge.info

The big people have the way the big people influence history, and the little people have the ways the little people participate in history.

On February 1, the 65th year of the scientific calendar, a lot of things happened, among which the most far-reaching event for later generations was the opening ceremony of the University of Science, when more than 1,000 people attended the opening ceremony, and all the others were students except for a teacher in Tianfang, but these people finally formed several systems, and these systems have influenced all generations.

As the initiator, Tianfang, as a butterfly coming from the outside world, is no longer hiding in the corner and secretly flapping its wings, but showing its hideous fangs and slapping the wheel of history fiercely.

And then there is another far-reaching thing, the shadow of the subordinate of the Immortal Palace, stole a tube of things from the Huang family, which can be regarded as cracking a huge conspiracy that can affect the entire human civilization, of course, stealing this thing is only the first step in cracking it, and there are too many things behind it to develop around this small incident.

Third, Lei Zhen, the marshal of the Asgard Legion, signed a cooperation agreement on the procurement of firearms and bullet OEM with the other four legions on behalf of the Asgard Legion, and of course there is a full range of military cooperation agreements, except for the Bai Family Legion, the other legions all felt that the benefits were far higher than the price paid after weighing the pros and cons, so they signed the agreement very happily and got the firearms suitable for their respective legions' shares, as well as the two million war bullets and 10 million training bullets paid by the Chaos Asgard in advance, and of course, the Chaos Legion also sent people to be responsible for training each spear battalion。

Since then, the defense line of the Terrans on the battlefield of the Ancestral Star has been extremely strengthened, and various tactics have been evolved on this basis, and the demons have been temporarily beaten and complained, and the pressure on the Terran defense line has been greatly reduced.

Of course, there are also insignificant little things, there is a lack of records in history, only in a certain biography of a character is better than nothing, a few words mentioned a stroke, Li Yuanba challenged Mo Chou, in the case of Li Yuanba's hole cards, failed miserably in Mo Chou's hands, could not turn up any wind and waves at all, once became a laughing stock that was not as good as the girl, mainly Li Yuanba was too arrogant, and he could only ridicule before the opening, and the result was a failure in the challenge and became a laughing stock.

At the beginning of the challenge, he boasted about Haikou, and wanted to beat everyone down in the second grade, but he didn't even do Mo Chou, Mo Chou said directly on the stage: "Even I can't beat it, and I still challenge Fang Wen, the first in the second grade, it's purely looking for! Also, I didn't bother to say it, but you're really not as good as a girl!"

Mo Chou put away his sword, regardless of Li Yuanba, who was spread out in the ring, Shi Shiran left, this time it was a willful hand, otherwise he would not have bothered to take care of such a mentally handicapped at all, but he just ignored him and kicked his nose in the face, so he had to teach him a good lesson.

When Li Yuanba was lying in the ring and reflecting on his life, Tianfang was planting the seedlings of the World Tree, which was known as the Tree of Science and Technology by later generations, on a vacant lot outside the University of Science.

The World Tree seedlings grew at a visible rate, growing from less than a knee to more than a person's height, with luxuriant, lush and thriving foliage. Planting the World Tree, the entire opening ceremony is completed, but the entire opening ceremony is only two things, the other is Tianfang's speech, a total of only three sentences: "First, the purpose of our school is to change the world with science, science is the primary productive force, and science is combat effectiveness." Second, our school is all about teaching science. Thirdly, today, the University of Science is officially established, and the enrollment of students is started, and the first batch of students is invited to register and go down in history forever!"

And the facts have proved that all these three sentences of Tianfang have been realized, and they are not empty words.

After the opening ceremony, Tianfang held a big pen and wrote the four big characters of the University of Science on the blank stone wall at the school gate, while the hard-pressed Gao De sat at the gate, registering the roster of the first batch of students, and of course, distributing teaching materials.

Gao De happily took advantage of his position to change his student number to No. 1, and the fat man and Yang Xiao were No. 2 and No. 3 respectively under the signal of Tianfang.

Gao De didn't have time to register alone, and in the end, the fat man and Yang Xiao were pulled out because of the queue registration, and they also helped Gao De register and distribute teaching materials, and these things alone were busy for a whole day.

In the evening, the front of the entire large classroom was full of people, and the seats in the back were all vacant.

It was the first time for everyone to have close contact with such an advanced projection teaching device, and of course, the most important thing was that they were completely confused about the ghost drawings on the textbook, and they were all discussing one by one.

Finally, when Gao De, Li Xiuyuan, Yang Xiao and another student with student number 1533 entered the big classroom and took their seats, they sat on the podium and looked like they were closing their minds, but Tianfang, who was actually planning to prepare for class, finally opened his eyes.

Tianfang stood in front of the big blackboard, took the microphone, and began the first lesson that affected the entire history of the universe: "As I said earlier, what we learn is science, of course, the meaning of science in my understanding is the abbreviation of learning by subject!"

Tian put it on the blackboard and wrote a big word science: "Why do you want everyone to learn these things, in fact, we hope that our cultivation system, alchemy system, and refining system will have a better development, and after careful consideration, I have temporarily divided it into three major categories, and the sub-categories are not counted! Of course, all these sciences have a common basic knowledge, that is, arithmetic, I call him mathematics, which belongs to a branch of science!"

"I believe you have already read this set of textbooks in your hands, many people don't understand what the ghost drawing on it is, I will explain the most basic things now!" Tian put on the blackboard and wrote the Arabic numerals from zero to nine, and then wrote the corresponding number text below.

"Look, these are the new numbers I invented for the convenience of arithmetic, you see, this is to represent one, this is to represent two, this circle is to represent zero!" Tianfang said: "Let's check the original number to see, is it easier to write such a symbol, more convenient!"

Tianfang wrote down the five symbols of addition, subtraction, multiplication, division and equal sign: "These numbers represent addition, subtraction, multiplication and division respectively, and this symbol is an equal sign!"

Then Tian put it on the blackboard and wrote the Arabic writing of 1*2+6/3=4, as well as the writing of the original text.

Everyone below understands, a few strokes can write out a set of calculations, and the original way of writing, one times two plus six divided by three equals four, a full thirteen words, not counting strokes, which is good and bad, everyone at a glance, everyone admires the genius idea of Tianfang.

Mathematics is the foundation of the scientific knowledge system that I am going to teach you, and the basis of mathematics is addition, subtraction, multiplication and division, so what I am going to talk about today is the basic rules of addition, subtraction, multiplication and division.

"First of all, I position addition, subtraction, multiplication and division as a two-level operation, addition and subtraction is the first-level operation, multiplication and division is the second-level operation, in an equation, if there is a first-level operation and a second-level operation at the same time, the second-level operation is calculated first, and then the first-level operation, such as the above problem!" Tianfang pointed to the things written in front of him: "1*2 and 6/3 belong to the second-level operation, and the addition in the middle is the first-level operation, then we will first carry out the second-level operation, and the resulting equivalence is 2+2=4 This is the truth!" ”

"Of course, there are simpler ones, for example, all of them are first-level calculations, or all of them are second-level calculations, so you can follow the method of calculating from left to right!" Tianfang wrote another question on the blackboard: "Of course, there are slightly more complicated ones, such as the combination of first-level and second-level operations in the first-level and second-level operations, such as this problem, (1*2+7)/3=3, there is a parenthesis in this question, which are these two semicircles, I call him parentheses!"

"If you encounter such a problem, first calculate the formula in the parentheses according to the rules of the first-level and second-level formulas, calculate the answer, and then calculate the formula outside the parentheses!"

"This is the foundation of the foundation, so please take a closer look at the description in the textbook, yes, that is, find this book with the number 1, open it and look at the description of the first two pages, and, give me all the questions on the third page of the textbook, just use an ordinary pen, don't use spiritual power!"

There was a writing voice from the stage, everyone admired the mathematics of this system, when I used to learn arithmetic, it would give you so many rules, it was completely taught by the old gentleman casually, knowing addition, subtraction, multiplication and division, and now the teaching method of Tianfang seems to have opened a door, and everyone is easier to learn, more systematic.

Tianfang waited for three minutes, and then wrote the answers to the twenty questions on the third page on the blackboard, these twenty questions are the basis of addition, subtraction, multiplication and division of integers, Tianfang believes that as long as he learns, there will be no problems with the addition, subtraction, multiplication and division of this integer.

The answers were written on the blackboard one by one, and the people below also began to look at their answers against the blackboard, the people here are definitely smart, Tianfang has not done too much research, but the utilization rate of the brain is definitely higher than that of the earthlings, especially those who have reached the stage of cultivation and devotion, Tianfang estimates that the utilization rate of this brain has definitely reached more than half, although due to the problem of functional areas, there is no geometric multiple increase in IQ, but it is definitely a lot of growth.

Of course,When accepting a brand new thing,Everyone's ability to accept,And the speed of acceptance is different,Tianfang simply explained for a few minutes,All at once everyone has to learn completely,Tianfang didn't think so,But overall,Tianfang is more satisfied。

Because when Tianfang asked the person who had the wrong answer in the primary election to raise his hand, the entire 1,533 people, more than a dozen people raised their hands.

"Very good, one hundred and twenty-two, what are you doing wrong?" Tianfang asked, everyone was assigned a student number when they registered on the roster, and the seats were seated according to the student number, so Tianfang didn't need to remember the name, just report the student number.

"This young master, I was careless and wrote it wrong, I was right in my calculations!"

"Mathematics is a rigorous science, as it is said, the difference is a thousand miles, and when dealing with mathematics in the future, we must have a pious mentality, and we must not be careless!"

The fat man poked Yang Xiao on the side: "This third child is really a gentleman's material, and he is easy to understand!"

Yang Xiao nodded, however, he also admired Tianfang, an addition, subtraction, multiplication and division can tell so many doors, and so many rules, I believe that the future study career will be fun, as the knowledge becomes deeper and deeper, it will definitely become more and more rigorous.

"So, this one hundred and ninety-seven, what are you doing wrong?" Tianfang said.

"I was wrong in the fifth question!" No. 197 said embarrassedly: "Please explain it again, young master!"

"(15*3+5)/(10/2-3)-25 This question is actually what I just talked about, you can first take the equation in the two parentheses as an independent equation, 15*3+5 calculate, it should be 50, 10/2-3 should be 2, then the operation outside the parentheses, also have to comply with the first two level calculations, and then the first level of calculation, that is, 50/2 should be equal to 25, and finally you calculate step by step, in fact, it is 25-25 = 0," the day is written below, (45+5)/ (5-3)-25=(50)/(2)-25=25-25=0 calculation steps: "If you encounter something unclear, you are like me, calculate it for him step by step, don't write the answer all at once, so that there will be no mistakes!"

"Understood, young master, I have no problem!" said one hundred and ninety-seven loudly.

At least half of the next day was due to careless miscalculation, and the other half was similar to the problem of No. 197, which was a bit vague about the order of multi-level operations, as long as it was explained, it had been corrected.

The first step of this mathematics is to be explained, everyone can achieve a very high accuracy rate in the addition, subtraction, multiplication and division of integers, the most basic of the most basic, even if it is laid, it will be a long-term learning process in the future.
