Symbols:Inequalities/Negation

Negation

 * $\ne, \not >, \not <, \not \ge, \not \le$

Negation.

The above symbols all mean the opposite of the non struck through version of the symbol.

For example, $x \ne y$ means that $x$ is not equal to of $y$.

The $\LaTeX$ code for negation is  followed by the code for whatever symbol you want to negate.

For example:  will render $\not \ge$.

Note that some of the above relations also have their own $\LaTeX$ commands for their negations, for example  or   for.
