## Absolute Value Symbol

The general method to display an absolute value (or the modulus symbol) in LaTeX is by surrounding the number, variable, or expression with two vertical lines, `|`

.

|x + y| = 1

The keyboard shortcut for the this symbol isAlt + 124. To use this shortcut, press Down the [Alt] key whilst typing 124.

Check the following example:

% Abs symbol in LaTeX This is an example of an absolute value symbol $|x+y|$.

Compiling of this piece of code yields:

## Method 2: Using left vertical and right vertical commands

In this method, we can use the `\lvert`

and `\rvert`

command. These two commands require loading the `amsmath`

package. Check this example:

% Required package \usepackage{amsmath} %... Modulus symbol for inline equations, $\lvert x + y \rvert = 1$

which yields the following output:

## Method 3: Using mid command

Another similar command is ** \mid** command. This will have

**larger spaces between the modulus symbol and other characters**.

Modulus symbol for inline equations, $\mid x + y \mid = 1$

## Big absolute value latex

The following table highlights different LaTeX commands that can be used to get big vertical line for absolute value symbol (big modulus symbol):

Description | LaTeX command | Output |
---|---|---|

Absolute value symbol | | \frac{e^2}{2}x | | \( | \frac{e^2}{2}x | \) |

Using right and left commands | \left| \frac{e^2}{2}x \right| | \( \left | \frac{e^2}{2}x \right | \) |

Using big command | \big | \frac{e^2}{2}x \big | | \( \big | \frac{e^2}{2}x \big | \) |

Using bigg command | \bigg | \frac{e^2}{2}x \bigg | | \( \bigg | \frac{e^2}{2}x \bigg | \) |

Using Bigg command | \Bigg | \frac{e^2}{2}x \Bigg | | \( \Bigg | \frac{e^2}{2}x \Bigg | \) |
