An evil form of magic that only the
best of sorcerers can master. Not only does it involve numbers, but letters (mostly
x and y). They somehow rearrange themselves into supposedly simpler forms of themselves. I don't know how because I have not mastered the dark magic of algebra yet, nor do I intend to. Teachers
try to teach you formulas to learn the magic, but half the time it would only take a
true sorcerer to know what's going on.
