# How to rotate text by 180° and or mirror it in Math.SE?

I'd like to rotate and mirror text left-right in Math.SE, as plain text or inside formulae. What I tried is from a TeX post or this one like:

$\require{rotating}$
$\require{graphicx}$
$\rotatebox{180}{Text}$


but all I get is

$$\require{rotating}$$ $$\require{graphicx}$$ $$\rotatebox{180}{Text}$$

If possible, I'd prefer a solution that does not use special charactes like $$\forall$$ ($\forall$) for an unside-down $$A$$.

Combinations of rotations of 180° and mirror about vertical axis will do for me.

• It has some shortcomings, but take a look as this previous Question to see if it gives a satisfactory result. May 15 at 16:04

Horizontal mirror: F\mapsto\;\style{display: inline-block; transform: scale(-1,1)}{F} gives $$F\mapsto\;\style{display: inline-block; transform: scale(-1,1)}{F}$$ Vertical mirror:F\mapsto\;\style{display: inline-block; transform: scale(1,-1)}{F} gives $$F\mapsto\;\style{display: inline-block; transform: scale(1,-1)}{F}$$ Rotation by 180º:F\mapsto\;\style{display: inline-block; transform: rotate(180deg)}{F} gives $$F\mapsto\;\style{display: inline-block; transform: rotate(180deg)}{F}$$ (or alternatively scale(-1,-1))
