Mathematically, there are different inequalities symbols to represent “greater than or equal to”. However, the ≥ symbol is used in 99 percent of cases. And there is a default `\geq`

command for this symbol.

Symbol | Greater than or equal to |

Type | Inequalities |

Package | asmmath, mathabx |

Command | `\geq` , `\geqslant` , …,etc |

Example | `\geq` → ≥ |

```
\documentclass{article}
\begin{document}
$$ a \geq b $$
$$ p \geq q $$
\end{document}
```

**Output :**

However, for other symbols, you need to use the `amsmath`

and `mathabx`

packages. For example

```
\documentclass{article}
\usepackage{amsmath,mathabx}
\begin{document}
$$ p \eqslantgtr q $$
$$ p \geqslant q $$
$$ p \geqq q $$
$$ p \gtreqless q $$
\end{document}
```

**Output :**

And you can use not symbol with each of the above symbols.

```
\documentclass{article}
\usepackage{amsmath,mathabx}
\begin{document}
$$ a \ngeq b $$
$$ a \ngeqslant b $$
$$ a \ngeqq b $$
$$ a \gneq b $$
$$ a \gneqq b $$
\end{document}
```

**Output :**

With the help of latex, the command of all the symbols related to greater than or equal to is explained in this tutorial. I hope, you have found the answer to your question.
