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 :**
