Chapter 243 (2/2)

My special I'm still a kid!

”Foundation student, here comes the car!” Cheng Nuo waved to Wang Ji.

At this time, Wang Jian no longer tangled with the issue of health and health. While taking money from his pocket, he asked, ”boss, how much is it altogether?”

”It's eighteen in all. You can give me 20 directly. Don't change it.”

”Good. Here you are. ” With that, Wang Ji handed a 20 yuan bill to the gluten brother. Then he hurried to the car and opened the door to get on.

A few minutes later, a wail came out of a car far away from here.

”Sister, I bought two pieces of dough

…………

Because of the ”two yuan” incident, Wang Ji, who has always regarded himself as a mathematical genius, was depressed all the way. Even a little suspicious of life.

Back at school, because Cheng Nuo didn't know where the other two students' dormitories were, Wang Ji's eyes were empty. It was almost impossible for him to recover from the blow just now, so he had to put all the books and stationery he had sold back to his dormitory.

”Sleeping trough! Cheng Nuo, you just came back from robbing the bookstore? Why do you buy so many things? ” Seeing a lot of things that Cheng Nuo brought back, Yuan Hua couldn't avoid making a fuss.

Cheng Nuo wiped the sweat on his forehead and smilingly said, ”of course it's learning! I don't want you to be addicted to the chicken eating world. I am a good student who loves learning. If I don't study for a day, I feel sick all over! ”Yuan Hua:

Ha ha

Also do not know, a few days ago when eating chicken, play the most Hi, appeal to everyone to play all night who is that person?

”Come on, I'd like to ask my brothers. There's still something left to move up. Do me a favor.” Cheng Nuo will get off the bus when Wang Jixue long throw some of his own baking gluten as a reward.

”No problem.” The three of them are happily eating the baked gluten, and they go downstairs together with Cheng Nuo.

…………

The sixth day of national day.

When most of the students are still enjoying the wonderful National Day holiday, Cheng Nuo has to devote himself to the research of the project.

In the first part, the linear system of two-dimensional Helmholtz equation is derived by combining one-dimensional Helmholtz equation with compact difference scheme.

In the five parts of the project framework, this is the simplest part. So Jiang Shuobo assigned the task to Cheng Nuo, the youngest in grade.

At the same time, the first part is also the most basic part of the whole project.

If the linear system obtained by the two-dimensional Helmholtz equation discretized by CCD (joint compact difference) scheme has not been worked out by Cheng Nuo, the work of the latter four parts will not be carried out at all.

After all, the title of this project is to study the CCD format of two-dimensional Helmholtz equation!

Great pressure!

This is the first time that Cheng Nuo has received such a high challenge.

However, as the king of the three virtues in the new era, Cheng Nuo feels that it is incumbent on him to perfect the task of preventing him from being handed over.

So today, Cheng Nuo got up early. Ready to start his day of scientific research.

In order to pretend to be forced, Cheng Nuo will try his best.

The dormitory environment is too noisy, the library is too far, and there are too many loving dogs. Cheng Nuo is worried that he will not accept the psychological gap.

So Cheng Nuo came to a family near the school alone Internet Bar. A machine was turned on.

Then eat chicken in the Internet bar, under the confused eyes, slowly take out a treasure from the schoolbag.
