Marcus simply nodded and returned to his work. His chalk danced across the board, creating elegant mathematical proofs that seemed to build upon each other like a carefully constructed tower. He worked through the first transformation, showing each step with the kind of clarity that would make a textbook author envious.
Sarah pulled out her phone under her desk, secretly recording what was happening. Something told her this moment needed to be preserved. She wasn't the only one; Tommy had the same idea, his phone barely visible as he captured the growing equation on the board.
"Five minutes gone," Mr. Wittmann announced loudly, checking his watch with theatrical precision. "Only 15 more minutes of this charade. I hope you're all learning something from this—namely, the importance of knowing your limitations."
But as the minutes ticked by, Mr. Wittmann's smugness began to waver. Marcus had filled nearly half the board now, and even to someone trying not to look too closely, it was becoming clear that this wasn't random scribbling. There was a logic to it, a flow that even the most mathematically challenged student could sense.
"Mr. Wittmann," Sarah finally spoke up, unable to contain herself any longer. "I think—I think he's actually solving it."
"Nonsense!" Mr. Wittmann snapped, but his voice cracked slightly. "Miss Chen, I expected better from you than to be taken in by this—this performance. Just because someone can copy formulas from the internet doesn't mean they understand them."
"But he's not copying," Tommy interjected, finding courage in Sarah's support. "He's deriving them. Look at step seven. That's not in any textbook I've seen."
Mr. Wittmann strode to the board, his face now a dangerous shade of purple. He studied Marcus's work, looking for errors, for any sign that this was some kind of trick or cheat. But the mathematics was flawless. More than flawless, it was elegant—the kind of solution that mathematicians call beautiful.
"Where did you get this?" Mr. Wittmann demanded, his voice low and threatening. "Who gave you the answer? There's no way—absolutely no way—that a 12-year-old could solve this problem. Especially not..."
He caught himself, but everyone knew what he'd been about to say.
Marcus set down the chalk and turned to face his teacher for the first time since beginning the problem. His young face was calm, but there was something in his eyes: not defiance, exactly, but a kind of quiet strength that seemed beyond his years.
"Mr. Wittmann," Marcus said evenly, "you said if I solved this equation, your salary would be mine. Did you mean that, or were you just trying to humiliate me in front of everyone?"
The question hung in the air like a challenge of its own. Mr. Wittmann's face cycled through several emotions: disbelief, anger, fear, and something that might have been the first stirrings of panic.
