# Prime: some pictures off an emulator

I am now trying the new Prime calculator. As I am not a teacher or a student (not that I miss when I was one), my review will verse above all on the areas I master. At this point in time, they are mainly finance, though as an engineer I remember most of the basic scientific areas.

More tomorrow!
