-0

Invented by Benoit Pye in a fit of rage, in order to anger the entirety of Mathematics, and possibly also Economics. Once Benoit left CD Annex, -0 was left in a storage locker for years, until Percy stumbled across it while trying to find himself. -0 was cast as the replacement mathemagician reluctantly, but has since made the role their own, even taking the brave decision before season 5 to ditch the traditional mathemagician’s hat, a choice that further enraged the concept of Economics, ruining the budget for season 5.
