OMG! Number Munchers FTW!! Seriously, though the prime numbers level in that game was my favourite past time for a whole year at least. I played a remake which had prime numbers up to 4 digits, which was killer. Can't find it any more though
. On my ti-84+SE I have a game similar to number munchers called exponent test. All the questions are like 84^-2 or 37^3. It is almost impossible unless you cheat (use another calculator) but I got a score around 35... Where is this going? Oh yeah, NOWHERE. At least I'm getting there fairly quickly. Blah, blah, blah (chokes and dies).
