In fact, if this had happened in the past, Bai Zhun wouldn't have said anything even if he found out that his teacher had made a mistake.
After all, he had always kept a low profile. What he secretly read in the classroom was usually something he could only learn in high school.
Other than waiting to pick up his sister after school, he basically didn't think about anything else.
No one knew what was going on today.
Bai Zhun changed his usual behavior. Not only did he correct the wrong ones, he even wrote down three methods to solve the problem. The third method was actually easier to understand than the math teacher's.
The math teacher was a little embarrassed. After class, he pulled Master Li over. "What's going on with Bai Zhun? !"
Master Li waved his hand. "I'm not sure."
"If you're not sure, who knows? If you don't say it, then I'll call the parents!" The mathematics teacher took the textbook and left.
