Symbols:R/Non-Negative Real Numbers

Real Numbers

 * $\R_{\ge 0}$

The set of non-negative real numbers:
 * $\R_{\ge 0} = \set {x \in \R: x \ge 0}$

$\LaTeX$ also allows, but  does not recognise that as a valid code.

Variants

 * $\R_+$

The set of non-negative real numbers:
 * $\R_+ = \set {x \in \R: x \ge 0}$

$\LaTeX$ also allows, but  does not recognise that as a valid code.
