The new deskmate looked like an ant on a hot pan, flustered as she stared at question nine.
"Oh no, I'm doomed! I can't do question nine..."
Too busy with the arts festival, she completely forgot to check the papers in advance. Watching as the students in front stood up one by one, her deskmate was desperate and grabbed Jiang Lai's sleeve.
"Do... do you know how to do question nine?"
Jiang Lai glanced at it, then took out a pen and drew an auxiliary line on her paper, followed by writing down a formula.
As soon as she saw the auxiliary line and formula, her mind immediately became clear and open.
The new deskmate kept praying that no one in front would get stuck. Fortunately, she was lucky. Everyone proceeded smoothly.
When it was her turn, she stood up, went to the platform, drew the figure and the auxiliary line, then listed the formula for inference and transformation, and worked out the answer.
The homeroom teacher looked at her with a stern gaze.
