Mathematically, the use of equals and not equal symbols is much more. Equal symbols are represented by attaching two horizontal bars.

Properties | Value |

Symbol | Equal |

Package | Default |

Command | = |

Argument | No |

Example | = |

You can easily identify equal symbols. Because Equal Symbol has this on your keyboard.

```
\documentclass{article}
\begin{document}
$$ p = q $$
\end{document}
```

**Output :**

So, notice this program above, the direct symbol is used here.

However, you can use both \neq and \ne commands in the case of not equal symbols.

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

**Output :**

Also, you have noticed that dot, triangle, and circle are used on equal symbol in different cases.

```
\documentclass{article}
\usepackage{amssymb}
\begin{document}
$$ p \doteq q $$
$$ p \doteqdot q $$
$$ p \circeq q $$
$$ p \triangleq q $$
\end{document}
```

**Output :**

And greater than, less than, subset, and super subset with equal and not equal symbols used.

```
\documentclass{article}
\usepackage{amsmath,amssymb}
\begin{document}
$$
\begin{matrix}
\leqq & \geqq & \subseteqq & \supseteqq \\
\lneqq & \gneqq & \subsetneqq & \subsetneqq \\
\nleqq & \ngeqq & \nsubseteqq & \nsubseteqq
\end{matrix}
$$
\end{document}
```

**Output :**
