I don't understand the middle part.
Is that x an element of some set?
Like integers?
Like this maybe?
$\rm \{x|x\in\mathbb Z,~x\ge3\}$

zepdrix · Answer

Anyway :)
We're interested in numbers `greater than or equal to 3`.
That's what our set will consist of.

This is getting to be too much like math for me. I've seen math and it looks just like this. I'd listen to zepdirx, if it were me.

{x | x  I, x ≥ 3}  is difficult to read.  Are you certain you've copied the original problem down correctly?   What does that symbol after the 2nd 'x' represent?

mathmale · Answer

zepdrix' "We're interested in numbers greater than or equal to 3." is correct.  Now, how would you represent these numbers in set notation, beginning with {     and ending with }?
