The PRAGMA Advanced Document Engineering site has a lot of documentation and examples on the finer details of how to use ConTeXt for particular applications and effects. I discovered it during a search for documentation on how to use Layers for cover layouts, which lead me to the excellent PDF It's in the details.
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{align}
\sqrt{|a_{11} + b_{11} + \dots a_{nn} + a_{nn}|} & \leq \sqrt{|a_{11} + \dots + a_{nn}|} + \sqrt{|b_{11} + \dots + b_{nn}|}\\
x &= \sqrt{|a_{11} + b_{11} + \dots a_{nn} + a_{nn}|} \notag\\
y &= \sqrt{|a_{11} + \dots + a_{nn}|} \notag\\
z &= \sqrt{|b_{11} + \dots + b_{nn}|}\notag\\
x & \leq y + z \notag\\
&= Square~{} each~{} element ~{}x, ~{}y ~{}and~{} z~{}and ~{} compute
