It’s a very common mistake to write 2.000. You have to know that in English this is not correct, it’s 2,000 instead, with a comma (,).
So 5.000 is not correct!
When we write decimals, however, we need a point (.), for example: 4.35.
Pay attention because in Spanish it’s just the opposite, point for thousands and comma or point for decimals.
