Learn how to include the absolute value symbol in your LaTeX documents through several examples. Absolute Value SymbolMethod 2: Using left vertical and right vertical commandsMethod 3: Using mid commandBig absolute value latexConclusion 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 is Alt + 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): DescriptionLaTeX commandOutputAbsolute 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 | $ Big vertical line absolute value in LaTeX This has been considered in a previous post: "How do you make big parentheses in LaTeX?".
