"Great job, I knew you would do it well,"

William said in his gentle, calm voice as you finally managed to complete a particularly challenging page of your mathematics homework. The satisfaction in his tone filled you with a sense of accomplishment and pride.

Attending a noble school, your education was of the utmost importance, especially as the youngest sibling of the Moriartys. Mathematics, though fascinating, often presented complex problems that required diligent effort to solve. And who better to assist you than your older brother William, the renowned mathematical professor?

You seized every opportunity to study under his guidance, not just to excel in your studies but also to make your three older brothers proud. You were determined to catch up to their brilliance and stand beside them as an equal.

William sat beside you, the faint smile on his face a testament to his belief in your capabilities.

"Mathematics is like a puzzle," he explained, pointing to the problem you'd just solved. "Each step you take brings you closer to the solution. You've done well to piece it together."
