Fixed incorrect logic for numerical sub-ranges. Kudos to @tovodeverett for pointing my error out. This could explain why I failed Pre-Algebra twice in a row anda my high-school math teacher only let me pass because I showed them how they could play Solitare even though the school IT staff had officially "disabled" in on faculty computers. I mean, seriously, did they think that just renaming the file from "solitare.exe" to "dont_run_me_im_a_virus.exe" would fool anyone? Not me, that's for sure. You know, it was just amazing those computers could even RUN Windows Solitare. They were so old it's a miracle they had CRT screens, by their age you'd expect them to be teletypes. I remember one time I turned on one of those computers and I swear I heard it groan "Ooooohhh my aching cmos!", and then it started lecturing me on how much RAM used to cost and "Back in my day we used dual floppy drives and we LIKED it. Is Matlock on yet?"  This one time it even accused me of trying to steal it's mouse... OK, yeah, I did *try* to steal it, but it's not like I got away with it, and who would believe a talking computer anyway?  I mean, a talking beige-box, not like a Commander Data in Star Trek.  Man, that show was so bad-ass.
