The History of the Number System

It was the first number system created in the Western Hemisphere in like 100 years. And every number is actually composed of strokes that represent that number. You strike on the top and that's five so five with nothing under it is five and then you five with one stroke beneath the six what the five stroke with two strokes beneath it is seven etc. When you get to the next five you do two strokes at the top that represents 10 and then you add more strokes to the bottom until you get up to 20 and then you start over at one and zero.
