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 $\Vert e_k\Vert$
