Search by topic:   15797. The Number Zero. This paper traces the history of the number zero and outlines its purpose in both ancient and modern times. Notes that zero in its modern conception arose about 200 A.D., but has historical roots dating back 5,000 years to the Sumerian culture. Explains the two major uses of zero (first, as a place indicator; second, to indicate a quantity of nothing) and their related concepts. 5 pages, 12 footnotes, 5 bibliographic sources.   $35 Copyright 1998-2018 Berkeley Research
