| Hi Greg, This is a LaTeX question. The short answer is "use the vertical bar key on your keyboard." For a longer answer, this is what a Google search for "absolute value latex" found:
LaTeX provides parenthesis-like symbols that will expand vertically so that they are tall enough to look well-matched to the height of the formula that they enclose. As an example, take the source code: \[ left| frac{A+B}3 right| \] It produces a displayed version of the formula |(A+B)/3| in which the absolute value delimiters are expanded somewhat in length. NOTE: The symbol | is located above the backslash on most keyboards. It works properly only in math environments. You can also use \vert to get the same result.
