    Modulus

    Good Morning world.

    How does one get the modulus sign for an equation like this |x-2|
    |x-2|


    I copied and pasted that as an example, where do you get the vertical slashes?
    Thanks in advance.

    It depends on the keyboard you're using... To get "|" I type Alt + Shift + l. (the last symbol is the letter L)

    If there is no key on your keyboard with the symbol "|" you can use \vert and \Vert :

    • \vert x-2 \vert gives \vert x-2\vert
    • \Vert e_k \Vert gives \Vert e_k\Vert
