Both versions are correct, it is just to personal choice.
I myself say 'twenty ten'
Either twenty ten or two thousand and ten.
It is correct to say the year either way, but it is more customary to say twenty ten, just as 1995 was said to be nineteen ninety-five, 1776 was said to be seventeen seventy-six, etc.
Twenty ten to twenty eleven
two thousand and twenty.... if you are talking about the numbertwenty twenty if you are talking about the yearIf you disagree heres a example of why it is twenty ten ( year )eg. do you think people called it one thousand nine hundred ninedy eight when it was 1998, no they called it ninteen nindy eight. So when the year is over 2010 people will be saying twenty ten, twenty eleven and so one
"Ten thousand to twenty thousand"
Twenty-ten or two thousand and ten are both acceptable. ____________________________ The consensus seems to be "Twenty-Ten". I suspect that this will be a matter of discussion for another 12 months.
two thousand, ten
Nine thousand, twenty-five ten-thousandths.
23,000 or 20,000+3,000 or twenty three thousand
Twenty million, ten thousand, three hundred sixty-seven.
The number 2010 is "two thousand and ten."The year 2010 has likewise been pronounced "two thousand ten" as a carryover from 2000 (a milennial number). However, the traditional form for years is the hundreds name, so the standard form (historically) will likely become "twenty ten" (and twenty-oh-nine for 2009). This has an advantage in speech to indicate that it is a year, not a number.
Ten thousand from 20 000 or twenty thousand minus ten thousand equals 10 000
