Re: Set-Builder Notation

Does between include the endpoints ? As you have written here:

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

Hmmm ... I was extending the concept of {2, 3, 4, 5, 6} so I may just reword it.

Re: Set-Builder Notation

Hi Maths;

Maybe saying, between 2 and 6 inclusive, might clear any ambiguity. Just a thought.
