Roster Method
If we use the symbol D to denote the set of NYC boroughs, then we can write D = {Brookkyn, Queens, Manhattan, Bronx, Staten Island}. This method of denoting a set is called the Roster Method.
Use the Roster Method to denote the first 4 books in the New Testament.
Let N = the set of the first 4 books in the New Testament.
N = {Matthew, Mark, Luke, John}
I think this is correct.

Re: Roster Method
Yes that's right. I've never heard it called the roster method though. Always good to learn something new.

Roster Method is the term used by Michael Sullivan in his College Algebra Edition 9 textbook. He is a famous mathematician and professor. I think he is retired by now.

Re: Roster Method
Roster method is a common term for just listing the elements.
While we're talking, note that order does not matter; an element is either in or not in a set.
So {a,b,c} = {b,a,c} and any other permutaion.

You are right. This is exactly stated in the textbook.
