I was worried the wording was a little unclear - but, as I said, it's just
how I personally do it. I'll elaborate..
When one crosses from 100's to 10's (but not from, say, 100,000 to 10,000) -
with any number of zeros on either side - insert an "and". This creates,
usually, a kind of ending to otherwise drawn out numbers. E.g., "1,234,567"
becomes "One million, two hundred and thirty-four thousand, five hundred and
sixty-seven" - the last "and" gives a feeling that the number is about the
The other time I include an and is when, within one group of three digits, I
cross from the hundreds place to a tens place or a ones place. For instance,
"One million, one hundred and thirty-four thousand". To me, the "one hundred
and thirty-four" is one number being placed in the thousands grouping, and
so you have the same usage of "and" there.
"One million, three hundred thousand and four" had the "and" by the first
rule. You go cross the 100-10 boundary, so you include the and.
"One million, three hundred thousand one hundred" would not have any "and"s,
as I would speak it.
As for the other question, if you want to cite me, that's fine, but like I
said I'm not any authority - just one person giving their take. ^_^
~6 out of 5 statisticians say that the
number of statistics that either make
no sense or use ridiculous timescales
at all has dropped over 164% in the
last 5.62474396842 years.
