"...from this, we can conclude that the answer is s60°, which is one-half."
"So which option should we choose for this question?"
The homeroom teacher swept a sharp gaze across the class, then paused to wait for an answer.
Everyone looked up at the blackboard. Even though the answer was practically on the tips of their tongues, only a scattered few called out B.
Zhou You was the loudest among them.
"That's right, B."
"All right, let's move on to the next question..."
Riiiiing-
The bell the students had long awaited finally rang, and delight appeared on their faces.
"Finally, it's over!" The Jade Seal let out a long breath. It had been forced to sit through an entire math lesson. What torture.
If the Jade Seal had grown a pair of arms, it would have been stretching them by now.
Its grounding in math was even weaker than Nuomi's. Nuomi had attended several more math lessons than it had.
The Jade Seal had been sealed away for a thousand years, and its mathematical knowledge had remained stuck in the Tang dynasty.
Functions, derivatives, analytic geometry, ellipses, hyperbolas, f()-to it, they were no different from an inscrutable heavenly script.
The students closed their test papers out of habit. The forty-five-minute lesson, which had felt as long as a century, was finally over.
"What are you doing? Did I dismiss you? I'll finish explaining this question before we end class!"
The authority in the homeroom teacher's voice made the Jade Seal tense up.
"You don't pay attention in class, but the moment it's over, you're all full of energy!"
Then the Jade Seal came to its senses. Wait, why am I getting nervous? I'm not a student.
Another five minutes passed before the homeroom teacher finished explaining the last math problem
