Tips
1,000+ are also similar to English, but there are a few things to note
The separator is a period or space, rather than a comma
Mille does not finish with the letter S
When pronouncing a long number, one generally pauses after mille before pronouncing the rest of the figures. The word euro finishes with the letter S when used as a plural, but must be written in lower case.
