"Ding~~"

"Congratulations to the host, the math level has been improved by one level, the comprehensive evaluation is S, and an additional random lottery opportunity will be awarded!"

On Friday, at noon, in the library, when Liu Yichen finished the fourth set of Huanggang Secret Papers on Compulsory Course 1, the mechanical metal sound of the system suddenly sounded in his mind.

"What the hell~~ What's going on? Why was it upgraded inexplicably?" Liu Yichen was startled, and then he immersed himself in the system, and then saw the interface display:

a:Mathematics:lv2(0/50)

b:Physics:lv1(2/20)

c: Biology: lv1 (2/20)

d:Chemistry:lv1(2/20)

e: Chinese: lv0 (4/10)

f:English:lv0(4/10)

Points:31

Lifespan in the upper left corner: 366 days

According to the system's determination rules, if you reach lv2 in mathematics, it means that you have basically mastered the knowledge of high school mathematics.

Liu Yichen was a little confused as to how the system made this determination. Could it be because he had made 4 sets of Crown Secret Volumes?

If this is the case, if he is willing to study Huanggang Secret Papers every day, wouldn't he be able to become a master of mathematics in a month?

"System, lottery!" Liu Yichen thought to himself, and then saw the familiar lottery roulette appear on the system interface.

"Stop!" Liu Yichen shouted secretly.

"Congratulations to the host, I got an ASUS a8tm notebook. The market price of this notebook is 14,300 yuan." The system's voice sounded.

Liu Yichen almost spewed blood, this... Damn it, the math level has been upgraded to lv2, the comprehensive evaluation is S level, and the random lottery opportunity obtained is such a notebook?

So disappointing!

Liu Yichen was so depressed that he vomited blood, but something was better than nothing. He went back to the dormitory, but none of his roommates were there. Liu Yichen took out the lottery reward, a backpack, which contained an a8tm notebook, a mouse, a mouse pad, and a charger.

, LCD screen cleaning fluid, brushes, etc., a complete set is provided, even invoices and warranty cards are included.

"This notebook is so ugly!" Liu Yichen looked at the notebook and complained. Looking at it from the perspective of more than ten years later, the appearance of this notebook is almost disgusting.

I opened the laptop and took a look at the configuration. The configuration is pretty good. The LCD screen is a 14.1-inch mirror widescreen, equipped with ASUS's unique splendid bright color engine. The camera is the standard configuration of the a8 series. The pixels of the camera are only a measly 35.

Megapixel, which is a relatively high configuration in this era.

Looking at other configurations, a8tm uses amd turion64 x2 processor, clocked at 2.0ghz, nvidia nforce 410 mcp chipset, nvidia geforce go 7600 independent graphics card, 2x1gb ddr2 667mhz memory, 120g 54 00rpm sata hard drive, built-in dvd burner. As for the interface

In terms of aspects, it is equipped with 4in1 card reader, DVD burner, express card slot, usb2.0 interface, ieee 1394 interface and audio interface, 4 usb2.0 interfaces and infrared port, s-video, vga, dvi, network card,

The modem interface and keyhole are both configured.

"The market price of this thing is actually 14,300 yuan. If 10 years later, no one will want 3,000 yuan." Liu Yichen complained endlessly: "It seems that I have to find time to go outside to get wireless Internet access."

It's not enough to have a laptop, you have to be able to access the Internet, and since there are no Internet cables in the dormitory, it's obviously not possible. What you can do is wireless Internet access, which depends on the traffic.

Turning off the notebook and putting it back into his backpack, Liu Yichen put the backpack in his cabinet and locked it up. This thing cannot appear in front of the teacher, nor can it appear in front of his family in a short period of time, otherwise it will be difficult to explain.

In the afternoon class, Liu Yichen was still 5 minutes late, but he shamelessly entered through the back door. The teacher saw it. Liu Yichen did not panic and sat firmly in his seat. The teacher did not say anything and continued to teach.

"Liu Yichen, come up and answer this question!" Suddenly, Lu Jun's voice sounded.

When Liu Yichen saw a question Lu Jun had just written, it was about the operation of logarithms, but it was obvious that he had not yet been taught this.

"Teacher Lu is really naughty. I thought he would pretend he didn't see it, but in less than 10 minutes, his revenge came." Liu Yichen muttered to himself. He knew that if he failed to solve this problem, then

Lu Jun would use the topic to his advantage, and then make himself stand at the door, kill chickens and scare monkeys, and establish prestige.

Liu Yichen's face was very calm. He walked up to the podium, picked up the chalk, and wrote below: log2(4^7×2^5)=log2(4^7)log2(2^5)=7log2(4)5log2(2)

=7×25×1=19.

Sample, with such a simple logarithmic operation, how can it be so difficult to find yourself? I really think that I have done Huanggang Secret Volume in vain.

A flash of surprise flashed in Lu Jun's eyes. He didn't expect that Liu Yichen could already do the knowledge he hadn't learned yet.

As for the solution process written by Liu Yichen on the blackboard, others were confused when they saw it, and they had no idea what it was.

Lu Jun did not explain, but erased the blackboard with a blackboard eraser, and continued to talk about exponential functions. He expressed the exponential functions in two different situations using a rectangular coordinate system, and then expanded them through graphics and properties.

The exponential function is an important part of the function. It involves the image, domain, value range, and properties of the exponential function. It lays the foundation for the functions learned later. If you don’t understand even the basic functions, the more complicated ones will follow.

Function, you don’t need to think too much about it.

Liu Yichen did not get distracted because he had finished studying, but listened carefully to Teacher Lu's explanation. After all, it was inevitable that there were some things that he did not understand in place, otherwise there would be no Huanggang Secret Volume that he could not do or

Questions that were done incorrectly.

There was only one math class in the afternoon, followed by physical education class. In this physical education class, Liu Yichen rarely took the initiative and proposed to form a class basketball team. As the first year of high school entered the second month of the first semester, the actual situation

Many classes in the first grade of high school have already formed basketball teams. Now they only form basketball teams in the eighth grade of high school, which is relatively late.

As a result, the class basketball team was formed relatively smoothly, with 10 people recruited, and Lin Ningwei volunteered to be a support staff member, so the class basketball team was formed.

"Dear teammates, as the saying goes, a snake cannot survive without a head. A basketball team also needs a captain to lead it. I volunteered to be the captain of our class basketball team. What do you think? I welcome everyone's challenge. Basketball relies on strength. As long as you use

If you beat me with the basketball in your hand, you can become the captain." Liu Yichen said to his 10 teammates.

As a result, no one took the initiative to challenge Liu Yichen, because they had all seen Liu Yichen play as the main player of the school team, and no one thought they could beat Liu Yichen.
Chapter completed!
