Leo stared at the blank page of his homework notebook. Problem 7(c) in Discovering Mathematics 4A stared back, its unfamiliar sigma notation and tangled algebra a personal challenge. He’d solved 7(a) and 7(b) with a bit of grit, but this one—a proof involving a sum of square roots—felt like a locked door.

A link followed.

The PDF opened on his phone screen: crisp, scanned pages with neat blue ink showing exactly how to rationalize the denominator and simplify the nested radical in 7(c). Relief washed over him. He could copy it in two minutes and be done. His phone buzzed
Leo typed back: “Yeah. But not the way you think.”
