Re: Set-Builder Notation

Hi MathsisFun;

Near the bottom:

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

What do you think?

In mathematics, you don't understand things. You just get used to them.
I have the result, but I do not yet know how to get it.
All physicists, and a good many quite respectable mathematicians are contemptuous about proof.

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.
