Aligning Mortality Two-sided Subscripts

Question

MWE:

\documentclass[11pt, twoside]{article}
\usepackage{amsmath}
\begin{document}
${}_{10}q^{1}_{30:40} = 0.17$
\end{document}

enter image description here

Is there any way I can align the subscripts on the left and right sides? The 1 should be on top of the 30, as displayed above.

Use \prescript{<sup>}{<sub>} from mathtools (which loads/extends amsmath):

\documentclass[11pt, twoside]{article}
\usepackage{mathtools}
\begin{document}
$\prescript{}{10}q^{1}_{30:40} = 0.17$
\end{document}

The problem with your code is that q has both a superscript and a subscript, so its subscript is placed differently than the subscript (with no superscript) on the empty atom {}.
