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}
\usepackage{xcolor}
\begin{document}
$$ p=\sqrt{a^{2}}={\color{red}\pm}\,a $$
$$ x= \frac{-b\,{\color{red}\pm}\sqrt{b^2 -4ac}}{2a} $$
$$ \frac{\partial y}{y}= {\color{red}\pm}\left( n\frac{\partial u}{u} + m\frac{\partial v}{v} \right) $$
\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.**

## Plus minus symbol in text mode

You cannot use the default `\pm`

command in direct text mode. However, with the `textcomp`

package, you can represent plus and minus symbols in text. And the most important command for this is `\textpm`

.

```
\documentclass{article}
\usepackage{textcomp}
\begin{document}
Use plus-minus symbol in text mode : \textpm
\end{document}
```

**Output :**

Use plus-minus symbol in text mode: ±

As you may know, single `$`

or double `$$`

dollar symbols are not used on both sides of the command in text mode.

And when you use a math mode command in text mode, you use single dollars on both sides of the command. For example

```
\documentclass{article}
\begin{document}
Use plus-minus symbol in text mode: $\pm$
\end{document}
```

**Output :**

Use plus-minus symbol in text mode : ±

## 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 | `\pm` → ∓ |

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 :**

## Use MnSymbol, fdsymbol, boisik, and stix packages for this symbol

Also, latex has multiple packages to represent this symbol. However, the interesting thing is that the same command `\pm`

is present in each package.

```
\documentclass{article}
\usepackage{MnSymbol,fdsymbol,boisik,stix}
\begin{document}
$$ a \pm b = c $$
$$ p \pm q = r $$
\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.
