Algebra. Joy.

Given me Arabic teacher's still flat on his back in medlab, and my Hindi teacher's just done a bunk, and my science teacher seems to have forgotten to give us any homework this week (which is weird - McCoy's been away with the fairies this week, must be all the work in medlab), and music appreciation is all up to date... it looks like it's me and the algebra book.

Fuck.

Numbers brains? A little help?
