Fifteen hundred

[ookami]

"A total of probably more than fifteen hundred engineers have passed through my classes."

fifteen hundred = 15 x 100 ? Wouldn't it be: one thousand and five hundred?

Fifteen hundred is a very common way of saying one thousand five hundred. It's faster and more streamlined.

Oxford gives this example,
in (the year) fifteen hundred = en el (año) mil quinientos;

In English both "fifteen hundred" and "one thousand five hundred" are correct ways to say the number 1500. Which one is the preferred way sometimes depends on what the number represents.

For the number of a year, we almost always say the four digits as 2 sets of 2-digit numbers, except for when both of the middle digits are '0'. A few year numbers may be said differently: for the years 2000-2009 it was more common to say "two thousand, two thousand one, ..., two thousand nine", although sometimes someone would say "twenty oh one". Starting with 2010 it is more common to say "twenty ten, twenty eleven, twenty twelve, twenty thirteen, ...".

The situation is different when a 4-digit number respresent a general number. For exact multiples of 1000 and the next 99 numbers it is normal to use "thousand": 1000 = "one thousand", 2017 = "two thousand seventeen", 9099 = "nine thousand ninety nine". However, for all other 4 digit numbers it is probably more common to avoid saying "thousand" except, perhaps, in formal or official contexts: 1234 = "twelve hundred thirty four", 2500 = "twenty five hundred", and so on.
