Symbols:Inequalities/Negation

Negation

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

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 $y$.

The $\LaTeX$ code for negation is \not followed by the code for whatever symbol you want to negate.

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

Note that some of the above relations also have their own $\LaTeX$ commands for their negations, for example \ne or \neq for \not =.
