I'm curious to see how others have handled the number systems of their worlds. Do your people do math like ours? Decimal system like Arabic numerals, or 20-based system like the Mayans? How do you write the numbers anyway? That is the main question, but it entails the others.
For me, every numeral is drawn as a part or whole of a circle. Attached is a document explaining there names and use and stuff, as well as what they look like. If there is HTML script leftover even after editing, my apologies. I made this first as a webpage when I was practicing HTML and so I might not be able to phase all that out.

	 The number system hasn't changed much. Just recently I realized the power of allowing the concentric inscriptions which the document says are not to be done, like a two around an eight. After all, how much easier would simplifying a fraction be if a number like 98 could be written as 7 x 7 x 2 just as easily? 98 divided by 7 no longer would be so difficult to figure if you could just see the sevens sitting there to be canceled. Some complicated maneuvers could be simplified with easy pen strokes, reducing error. So the way mathematicians use the numerals is still being worked out.
P.S., does anyone else have trouble seeing the pictures in the document? If so, try just clicking on one and adjusting its size, or adding spaces between them. Those tricks sometimes make them appear.
