Try the following example:

\documentclass{article}
\begin{document}
\begin{displaymath}
  \begin{array}{r@{\,\pm\,}r}
    48.0 &  3.2 \\
   153.5 &  0.1 \\
     3.0 & 10.0 \\
  \end{array}
\end{displaymath}
\end{document}

If you understand the structure, it's easy to see how to align on decimal
points.
