Although I'm interested in math, I've heard and read that the only math left to discover is in the airy range at the top of a mountain of other numbers and number systems. When I was in high school, I didn't know that, so I made up seven math systems of my own. Later, in college, I was told that three were unnecessary, three were already known, and one might be new. I soon learned that it didn't even matter, because one has to be a research mathematician at a university in order for math journals to be interested in publishing an article.
