Duotrigintillion or Dotrigintillion?Date: 03/14/2002 at 02:05:28 From: Webster Clervis Subject: Duotrigintillion or Dotrigintillion? My dad and I looked at some of the biggest numbers here today. He said I could send this. What number is right? Duotrigintillion or Dotrigintillion? Thanks! Date: 03/14/2002 at 08:53:48 From: Doctor Peterson Subject: Re: Duotrigintillion or Dotrigintillion? Hi, Webster. Both forms are used, if you can actually say they are used! Since names like these are mostly just made up in order to complete the list, people have different opinions and there's no authority to refer to for a final decision. Several other number names (or polygon names, and so on) vary in this way. I presume you saw these, which use "duo-": Decillion, Vigintillion, Trigintillion... - Dr. Math archives http://mathforum.org/dr.math/problems/trichardt12.10.98.html Numbering Systems and Place Values - John Knoderer http://www.mazes.com/numberingsystems.html and these, which use "do-": Names for Big Numbers - Dr. Math archives http://mathforum.org/dr.math/problems/kesselheim2.11.97.html Names for Large Numbers - Russ Rowlett http://www.unc.edu/~rowlett/units/large.html You might be interested in this site I recently found, which illustrates some of the variation you can find in similar terms: Numbers and Numerical Prefixes - Forthright http://phrontistery.50megs.com/numbers.html The fact is, correct spelling is not always as clear as modern American schools want you to think! You can choose which form you think works best; I lean toward "duo-" myself, as you see here: Powers of 10 - Dr. Math archives http://mathforum.org/dr.math/problems/melanie.07.14.99.html - Doctor Peterson, The Math Forum http://mathforum.org/dr.math/ |
