We would have no transportation, public or otherwise, without a numbering system that allows us to calculate precise locations? Decimal numbers, based on Arabic numerals, give us both precision and the ability, thanks to our positional numeral system, to express any number in fairly limited space (just try writing 10 billion in Roman Numerals!). Our numbers, or rather, the symbols that we use to represent numbers, come from India via the Arabs, during the Middle Ages (“… up to the end of the fifteenth century“). Any advocate for a democratic movement must both learn and share an understanding of number as system and statistic(s), for democracy to work well (there is also a need for good mass transit used by the middle classes, for a democracy to work well, but that is for another post, if you’d like):

1.) Find three different sources describing the source of our current numbering system/symbols,
2.) Share your findings with us, and, if you are more curious, tell us whether the Maya, the Aztec, or the Inca had a positional numeral system.
3.) Write a book, story, blog post or tweet that uses those findings, and then, please tell us about it! If you write a book, once it is published please consider donating a copy to your local public library.

includes two ‘imagination-rich’ walking tours, with songs, of Washington, DC. New interviews and research are woven into stories of old struggles shared by both the Jewish and African-American communities in the capital city.
Shared histories are explored from a new perspective of cultural parallels and parallel institution-building which brought the two communities together culturally and historically.
