## Main Question or Discussion Point

I was wondering how to express "x is a real number and not 1". What's the best way to express this? Right now I'm using...

[tex] x \epsilon \mathbb{R} \wedge x \neq 1[/tex]

But I'm sure there's a better way.

[tex] x \epsilon \mathbb{R} \wedge x \neq 1[/tex]

But I'm sure there's a better way.
