[texhax] series of mathematical expressions with textual remarks

[Krishnan E]

How about this?


\documentclass{article}
\usepackage{amsmath,amssymb}

\begin{document}

\begin{alignat*}{2}
  M:=\{& & &\qquad\qquad\text{($M$ is defined as)}\\
         & x\in\mathbb{R}\mid & &\qquad\qquad\text{(all elements of the set
           $\mathbb{R}$ for which)}\\
         & & \exp(x)>1\} &\qquad\qquad\text{($\exp(x)$ is greater than
1)}
\end{alignat*}

\end{document}
