"Professor Shen, you should just think that there are only sixty, don't worry too much." Someone from below was already shouting.

"Mathematics, this is a mathematics class, I am a mathematics professor, you are a mathematics student, you actually made me blind, cover my ears and steal the bell?" Shen Yin teased: "However, seeing that you love mathematics so much, I suddenly feel a little excited, and sure enough, I am still too young." ”

"Haha." Everyone laughed.

Shen Yin walked up to the podium, put his books on the podium, and then said with a smile: "Welcome to my elective course, I just said, I am talking about mathematics, so we will start with the word mathematics." ”

Although Shen Yin brought textbooks with his lectures, he never spoke according to the textbooks, but relied on his own experience.

Theory plus experience, plus Shen Yin's lectures are interesting.

That's right, it's fun, for example, at this moment, Shen Yin said: "Those of us who do mathematics know that mental arithmetic is very important.

Many parents actually see this, so in many families, they begin to train their children to learn mental arithmetic at a young age, even if they don't use it in the future, they have multiple skills, they just think about it, they haven't thought about it, mental arithmetic is inseparable from our mathematical deduction.

In fact, before we write down each step of mathematical deduction, we must mentally calculate countless times in our hearts, and deduce countless times, but now many people, I find that the sadness can't keep up, and more people are using pen arithmetic instead of mental arithmetic. ”

Shen Yin smiled and said: "The mental algorithm is actually very simple, elementary school students can learn it, I will tell you the mantra now, you can try it." ”

Next, Shen Yin shared with you what is real mental arithmetic, which is mainly a mental arithmetic formula for primary school students in the future, but there is no one yet.

Since there can be a future, it is not enough to take it out sooner.

What tail is the same method, what head is the same method, what butterfly method, what overlapping method, etc., it can be said that Shen Yin gave them all with a grunt.

There are college students in front of them, and this kind of elementary school student stuff is just not available now, but it's all very simple, so it's very easy to tell them.

The people present listened with relish, and they found that these rules are really very useful, at least these rules are really very useful for them who are not good at mental arithmetic.

Shen Yin's class was ninety minutes, and this was a big class, so after ninety minutes, Shen Yin left some topics and left.

However, Shen Yin's class became famous because of this, and many people were annoyed, why didn't they grab Professor Shen Yin's elective course.

Shen Yin doesn't name them in class, learning this kind of thing is self-taught, and she doesn't think it's interesting to force these people.

Like herself, when she was a student, she learned everything she should have learned, so sometimes she would skip class, so the roll call was not within the scope of her teaching.

As for the number of people listening, she doesn't mind, as a professor and a teacher, all she can do is teach everything she can teach.

After Shen Yin finished class, she left, as for the reaction, the principal later called her to tell her, and she was very recognized for Shen Yin's new teaching methods, especially those mental arithmetic methods provided by Shen Yin, although they were a bit tricky, but it was undeniable that they saved a lot of time in mental arithmetic.

Back in the lab, Shen Yin continued her research on the phone.

"I always feel like there's one missing piece of data." Shen Yin frowned slightly after the experiment.

Shen Yin always felt that something was missing from the mobile phone he made now.

"Doctor, I actually think we're doing a good job." Zhang Zhang looked at the simulated data: "I don't see any flaws. ”

Shen Yin shook his head: "No, it's defective, the mobile phone I want is not only able to talk, but also needs to have other functions, such as it's a radio, it's a TV, it's a camera, it's a video recorder, not only that, it can also record, it can also participate in work, and it can also process files, I just thought about what kind of data is missing." ”

Shen Yin began to slowly record the data he wanted to record, checking it by the way.

Shen Yin checked carefully, and others didn't dare to disturb Shen Yin, and finally on the third day, Shen Yin found out: "I know, the mobile phone code I made is missing a 0 here, no wonder the simulation has not been able to achieve the effect I want, it turned out to be here." ”

Shen Yin quickly ran through the program, and then started the simulation again, waiting for the simulated mobile phone was really what she needed.

"It worked, we succeeded." The others cheered.

Shen Yin also had a smile on his face: "Prepare the materials, prepare for production." ”

The materials have been prepared for a long time, and now it's time to start making them.

I have to say that after Shen Yin and his research came out, they made the first batch of mobile phones.

Only ten mobile phones were made in the first batch, and when the mobile phones were put in front of Mr. Xia.

Mr. Xia was a little speechless, and directly asked Shen Yin to come over, looking at Shen Yin, Mr. Xia was dumbfounded: "You girl, why did you give me such a big surprise." ”

Shen Yin tilted his head and smiled, with a strange expression: "Don't you like it, sir?" ”

"How can you not like it, but you kid is also bold, you can complete such an important experiment by yourself, tell us earlier, and I can send someone to protect your laboratory." Mr. Xia had further insight into Shen Yin's boldness.

Shen Yin smiled and said: "Actually, it's good for me to be like this, no one doubts me every day, if you send too many people, it will make people wonder what is in that place." ”

Mr. Xia thought about it, and the practice of covering his ears and stealing the bell was indeed not feasible.

"Your phone came out this time, what are your requirements?" Mr. Xia continued to ask.

"The first cooperation is Zhou Shengluo, and I want to give the other mobile phones to my family, so I will give me twenty." Shen Yin said casually.

"You can say yes." Mr. Xia nodded.

Zhou Shengluo is an economic genius, and none of the factories he opened are low-profit, of course, this is inseparable from Shen Yin, the most important thing is that the equipment in Zhou Shengluo's company's factories is the most advanced.

"I heard that Zhou Shengluo has developed a high-tech production line by himself?" Zhou Shengluo is a genius economist, but it does not hinder his other developments.

As Zhou Shengluo said, when necessary, he will develop some things himself, such as the production line.

Shen Yin said on the side: "I heard that the factory is his, and the assembly line is not enough, so it is normal to develop it yourself." ”

Mr. Xia looked at Shen Yin for a while before he smiled and said, "You two are both treasures." But the rewards are not less. ”

Shen Yin didn't ask for any rewards, and she wouldn't be missing anyway.
