## Math Notation Help

This glossary will help you build complex mathematical equations using the Tex markup language. This will involve using @@ or $$before and after the expression to display the desired results.

${\rm~det}\left|\begin{array}{cc}a&b\\c&d \end{array}\right|$

("\rm~something" renders "something" in roman style)

 Keyword(s): absolute value symbol, determinant symbol
