@engineer,
Engineer, what you have "always heard" is, the (US) American way of expressing numbers in words. Canadians* and those using British English (Mainly used in Great Britain, Australia, South Africa, India and the rest of the British Commonwealth) use the word "and" as I have indicated.

Quote:The proper form for large numbers that must be written in full is as illustrated:
one hundred and fifty-two thousand three hundred and five.
(This is standard British English usage as well, although sometimes commas are inserted after powers of ten greater than one hundred e.g. "million", "thousand" etc.
Engineer and Setanta, you should
beware of making sweeping statements that such-and-such a thing is worldwide standard English usage based on "what you have heard", or what you may, no doubt, sincerely believe to be the truth, without doing a little checking first! This is especially important when purporting to give definitive advice to non-native English learners seeking advice.
