At the very least, you're going to need to go into the math of equation-based damage calculation. It's pretty god damn simple still, so don't worry about needing to know programming math.

More importantly than all of this is, what class are you presenting this to?
  1. If I had to do a presentation for my Calculus class, I'd probably go into something more complex, probably not even something based in an RPG, something like projectile motion in Angry Birds and how using derivatives in programing assigns characteristics to the motion.
  2. If I was making a presentation to an Algebra class, than RPG's would do nicely, but I'd have to at least look up the equations that decide how stats base damage for attacks and how equations differ for different attacks.


If you don't want to go as deeply as number 2, then you better be in an arithmetic class!
