"Just!"

"You can explain the problem-solving process." Liang Feng said: "Let's talk about it before."

Xu Mang was rushed to the classroom podium and looked at a group of classmates with strange eyes below. Not to mention the feeling of being superior, he came out like this.

"System, I need a perfect way to explain this question."

[After the system identified, the perfect explanation of this question is redeemed: 200 (mathematical skills)]

I'll go!

So expensive!

Sorry, goodbye.

"What are you going to be slow?" Liang Feng urged: "Hurry up!"

"oh"

In desperation, Xu Mang had to copy the process on the blackboard. After writing it, he did not forget to use chalk to click three times.

“It’s like this here.”

"And then it's like this here."

"It's like this afterward."

“That’s how it comes here.”

“That’s what comes next.”

Xu Mang spoke very excitedly on the stage, but Liang Feng below was about to collapse.

Did he do it alone?
Chapter completed!
