Can someone please explain to me how roster notation works?

Question

anonymous · Answer

Roster notation is used when you want to include single numbers in a set, and not a range. You will use { and } to mark a set, with commas between your solutions. Example: {1,3,6,6.3} for the four numbers given.

Food for thought, the last time I talked about roster notation was in 8th grade algebra class. I'm in college now and I have not talked about it since. :D
