# Symbols:R/Strictly Positive Real Numbers

## Real Numbers

$\R_{> 0}$
$\R_{> 0} = \set {x \in \R: x > 0}$

The $\LaTeX$ code for $\R_{> 0}$ is \R_{> 0}  or \mathbb R_{> 0} or \Bbb R_{> 0}.

MediaWiki $\LaTeX$ also allows \reals_{> 0}, but MathJax does not recognise that as a valid code.

## Variants

$\R_+^*$
$\R_+^* = \set {x \in \R: x > 0}$

The $\LaTeX$ code for $\R_+^*$ is \R_+^*  or \mathbb R_+^* or \Bbb R_+^*.

MediaWiki $\LaTeX$ also allows \reals_+^*, but MathJax does not recognise that as a valid code.
