Big Numbers
I'm going to join MUN(Model United Nations) but I've forgotten the numbers in English. Because, I'm taking japanese courses.
I am confused about numbers.
1965 - We read it like "nineteen sixty five"
2016- We read it like "two thousand and sixteen"
6852- But how do we read it?

360 - it can be read like "three sixty" and "three hundred and sixty". What's the difference between them? Is "three sixty" informal?

360 - it can be read like "three sixty" and "three hundred and sixty". What's the difference between them?  Is "three sixty" informal?

Answer

6852 - six thousand, eight hundred and fifty two.
360 -  best as three hundred and sixty.  Three sixty can also refer to $3.60 (three dollars and sixty cents).

Answer

6852 would be read as six thousand eight hundred fifty two.

360 is actually three hundred sixty. However, three sixty became a popular slang term for this number. There is even a company whose name is 360 (three sixty) as a result of this slang use. Because a full circle contains 360 degrees, a popular expression in the U.S. emerged for spinning in a circle. It is "to do a three sixty." I think that this may be its origin.
