You need to use the \pm command to get the** latex plus-minus symbol**. And you** do not need to pass any argument in this command.** So, take a look at this syntax below

Properties | Value |

Symbol | Plus Minus |

Argument | No |

Command | \pm |

Example |
\pm → |

For example, when you determine the square root of a number, you have to use the plus-minus sign.

```
\documentclass{article}
\begin{document}
$p=\sqrt{a^{2}}=\pm a$
\end{document}
```

**Output :**

If you look at the program above, you can see that the\sqrt{} command is used for the square root and **a² is passed as an argument.**

## Minus-Plus symbol in latex

Mathematically, when a character with a plus-minus sign(±) is multiplied by a minus sign(-), the plus-minus sign before that character becomes a minus-plus sign.

Properties | Value |

Symbol | Minus Plus |

Argument | No |

Command | \mp |

Example |
\mp → |

In the same way, to get the minus-plus symbol, you need to use the\mp command instead of the \pm command.

For example, you notice that when a plus-minus character is moved to the opposite side of a mathematically equal, it becomes a minus-plus symbol. So, look at this LaTeX program below

```
\documentclass{article}
\begin{document}
$a\pm b=0$
$\therefore a=\mp b$
\end{document}
```

**Output :**

Hopefully, you understand how to use the plus-minus or minus plus symbol with the help of latex. And no document has been created in this tutorial, only the equation is presented in front of you with a dollar sign on both sides. Thanks.
