At the same time, he was flipping through books and found relevant problem-solving cases.
The female teacher looked at Lin Beichen flipping through books as he walked and couldn't help but chuckle a few times.
"There are no answers in the books!"
"There are only cases, but even if there are cases, you can't understand them without explanations!"
"If you can't solve it, I will report to the principal, and you won't be allowed to miss any class in the future!"
"Also, you must complete... complete..."
Before the female teacher finished speaking, Lin Beichen had already walked up to the blackboard with the book in hand, without pausing or looking at her.
Instead, he grabbed a piece of chalk, and with a few swift moves, wrote down the answer!
Just like that, effortlessly!
Without even making a draft, he directly wrote down the answer next to the equal sign!
In the distance from his seat to the blackboard, Lin Beichen had already completed the calculation in his mind!
