Equation Library?

[Kewin Lund]

Hi Everyone
I just bought my Prime last week, and came from my old trusty 48GX, which has saved my butt several times during my studies as an engineer.
I'm also new to this forum, so bare with me.
Question:
Does the Prime have an Equation Library, similar to that of the 48GX model? I can't seem to find it anywhere?
If this is an app that needs to be downloaded, how do I do this and where to get this (and other) apps?
