|Really BIG numbers are normally referred to as an
exponential number such as 1.2x10 to the power of 60, but
there are names for such numbers as well. These names are
based on the latin prefixes for numbers with the body
'illion' tacked on afterwards. So, a decillion is the
tenth in line from a million, because dec was the latin
prefix for 10. (December was originally the tenth month,
until calendar makers decided it made more sense to have
twelve months and added two more.) By counting convention
the break points occurred every third power of ten, so a
million was 10 to the sixth, billion was ten to the ninth
and so on. Undec- is the prefix for eleven and so forth.
In Britain and Germany prior to this century, their system had break points every ten to the sixth power, so their billion was actually ten to the twelfth power. They used the Milliard for what we know as a billion. Now, however, all countries use ten to the third as the break points in counting.
The googol was a term created by mathematicians to
represent ten to the hundredth power. Here is a googol
