How to write all real numbers in set notation?

laila [671]

Hi, this is the notation for inclusion of all real numbers.

$x \in \mathbb{R}$

We can also state numbers which are positive or negative with a sign on top of the R notation like so:

$x \in \mathbb{R}^{+} \text{ or } x \in \mathbb{R}^{-}$
