"And that is why the square root of four is two," Hermione finished with a flourish. She regarded the chalkboard for a moment, watching a large, emboldened 2 hop about ecstatically just after an equal sign. Then she turned, beaming, to face Draco.

"This makes absolutely no sense whatsoever!" he sputtered, much to Hermione's dismay. "I fail to see why a number can be transfigured into a square when, in fact, it has always been a four. Unless, of course, by putting that disfigured box around it—"

"But that's not how it works!" Hermione cried, interrupting.

"Furthermore," he said, pressing on with a scowl, "it is impossible even for magically enhanced numbers to spontaneously grow roots. I thought this was an Arithmancy lesson, Granger, not Herbology class."
