You know, I never realized Roman numerals were a real way of counting, or doing math. I blame my half-assed education or my short adolescent attention span. Ahh, I blame both. Anyway I just never thought of them as real numbers, I thought of them more as a fancy, more old school proper way of writing numbers only when it was for show, like at the end of a tv show, or above the entrance to a school or something of that nature. The fact that it was how people counted a long time ago is crazy to me. The example of multiplying Roman numerals in this video drove it home, and now I get it. If you watch the video you’ll also learn where the decimal point came from, and how our current 0 through 9 symbols came to be. Pretty interesting.
