This was a miracle that happened again. Ethan Su spoke out the answer to the question as soon as he opened his mouth.
Then he re-did the complicated calculations, and Miss Grey opened her eyes wide and watched every step of Ethan Su's algorithm with her own eyes.

It still took 10 minutes for the question to be perfectly presented on the blackboard, with almost no mistakes.
