I still have a problem with pronouncing big numbers in English. Aside from all other issues, I found one single problem that I still haven't figured out how to use properly or "if" I can use it in the first place.
I frequently hear people speak, say, 1300 like "thirteen hundred" rather than "one thousand and three hundred." My question is, can I do this with any number in the range between 1000 and 9999?
For example, can I speak 5000 like "fifty hundred" and 2600 like "twenty-six hundred"?
I'm mostly wondering if this style of number speaking is commonly only used for numbers below 2000, or if it's applicable whenever it's more convenient than speaking the mixture of "thousand" and "hundred".
