This is something that's confused me for a little while now. What exactly is Arithmancy? All the references I've seen to it are pretty vague, so I figured someone here might be able to help. Is it like Muggle math, but applied to magic (kind of like wizarding engineering)? Like Geometry, Trig, or Calc used to help make wards and such? And maybe even wand movements? That's my personal preference, but I wasn't sure whether there was an actual description of the class. And I'm basing my idea off almost nothing. Anyone know?
