Chapter 449 (1/2)

Liu Qingyi's eyes are a little confused. She already thinks Shen Lang is abnormal enough. Unexpectedly, Shen Lang's mathematical skills are strong enough.

Guan Jing also covers her mouth and looks at the waves in surprise.

The old professor also looked at Shen Lang and praised: ”those who can work out the result of 2.13 are generally only highly talented graduate students in the Department of mathematics, otherwise they are mathematical talents. Because this last mantissa is very difficult to calculate! ”

The whole class was shocked again!

”This fellow, you are very accomplished in mathematics.” The old professor thumbed up with a trace of excitement on his face.

Shen Lang smiles and says nothing. Liu Qingyi and Guan Jing look at him adoringly.

Zhou Guangwen was not satisfied and cried, ”he must have done this problem before! Even I can't work out the answer in such a short time. ”

”That's just you, don't compare your level with my boyfriend's level!” Liu Qing hummed coldly.

With that, Liu Qingyi's face was slightly hot, and she was too hot. At that moment, she even imagined Shen Lang as her boyfriend.

The old professor waved his hand and said, ”this question is one of my own. No one else can see it in the reference book.”

Zhou Guangwen still didn't believe it and said, ”let's talk about the idea of solving the problem.”

The old professor asked to Shen Lang, ”this classmate, can you tell me your solution?”

”Yes, I'll write it for you.”

Shen Lang said a word, then went to the platform, picked up the chalk to write.

The class was surprisingly quiet. A group of students were staring at the waves on the platform.

Most of the students in the class can't do this problem, but it doesn't mean they can't understand the process of solving the problem.

Shen Lang just wrote out a few steps in a few strokes, but each step hit the point and was quite clear.

Students with slightly better grades can see that Shen Lang's problem-solving process is absolutely correct!

Soon, Shen Lang figured out the answer to the question.

The whole room was silent, and everyone's eyes were on Shen Lang, including the old professor, with an unbelievable expression on his face.

Shen Lang's steps of solving problems are simple and concise, and his knowledge of advanced mathematics has been brought into full play. This way of solving problems even makes old professors have the feeling of enlightening!

”In fact, there is another way to solve this problem.”

The waves didn't stop, so we continued to solve it in another way.

The whole class can't help but take a cold breath.

Zhou Guangwen's forehead exuded a lot of sweat, and his jaw couldn't close in surprise. He has always been a good result to rely on open-minded, now in front of the waves, his face a hot pain, as if he was slapped in public, even the head can not lift up.

Liu Qingyi's heart beat a little faster. I thought that Shen Lang was not human. At least Liu Qingyi had never seen such an all-round boy. It was so dreamy!

Only five minutes later, Shen Lang wrote another way of thinking and calculation on the blackboard without any omission.

The old professor excitedly gave a thumbs up: ”the second way to solve the problem with the function formula is simply ingenious, good! This classmate, you are really talented. Oh no, you are a genius, a wizard, a ghost... ”

”Pa Pa Pa!” Liu Qingyi took the lead in clapping.

Guan Jing also joined in the excitement, and then the whole class burst into warm applause.

I have to! Shen Lang is really capable. No wonder he can be Liu Qingyi's boyfriend.

The performance of this scene, also let the white eyed boys less. Zhou Guangwen was disheartened and seemed to have been badly hit.
