write about Numerical nomenclature

If your question is about naming (large) numbers, you may find the following link helpful: www.numericana.com/answer/culture.htm#zillion.

The same page includes info about other naming schemes for things like polygons or simple organic chemicals.  Another page on the same site will tell you all you need to know about the official multiplicative prefixes to use with physical units.

Hope this helps.

I posted this response before. Only problem is that person got banned for having several different names so you probably didn't see it.

01_ uno / meth

PJ, the second answers you've given for each number I believe are only applicable to omganic (carbon-based) compounds, like methyl propane.

For 1, what about solo- and mono-?
2: di
3: tri
4: quadr
5: pent
6: hex/sex
7: hept/sept
8: oct
9: non/enne
10: dec
11: undec
12: d(u)odec
13: tredec/triskaidec
14: quattuordec
20: vigint
100: cent (also googol if you mean 10^100)
1000: mill
1000000: mega

n-plex means 10^n, which is why we say googolplex instead of centillionplex
(plex part from DrGerard's reference)
