For instance, we can write instead of without ambiguity. Also, I defined an \abs command for the absolute value with the \DeclarePairedDelimiter command from mathtools to have the vertical lines adjusted to their contents. Use the split environment to break an equation and to align it in columns, just as if the parts of the equation were in a table. LaTeX assumes that each equation consists of two parts separated by a &; also that each equation is separated from the one before by an &. For an example check the introduction of this document.
