Re: Set-Builder Notation

Hi MathsisFun;

Near the bottom:

But how would you list all the Real Numbers between 2 and 6 ?

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

maybe this is correct:

What do you think?

In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Set-Builder Notation

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.
