Kapitel 108: Sylvana Knowledge

While the couple was still amazed by the test paper, Greed, who had placed all of the bags to the side, walked toward them with little Sylvana piggybacking on her back.

"Hm? What's this?" Greed picked up one of the test papers to examine it, with the little troublemaker still clinging onto her back like a koala.

"Is this Sylvana's test paper?" Greed asked, confusion evident on her face after seeing the results.

"Yes, she answered all of it in less than half an hour," Daniel replied.

A teasing smile appeared on Greed's face as she turned to the little troublemaker behind her. "Well? Little redhead, do you know what the derivative of f(x) = 3x^2 + 2x - 5 is?" Greed asked a question that would surely leave Koyuki's brain spinning.

"That's easy! It's f'(x) = 6x + 2," Sylvana answered confidently. However, instead of receiving a round of applause or even a word of praise from her parents, she was met with complete silence.
