I am sure that this has been answered here many times, but I can't find a duplicate.
My question is what to do with lines that are "too long", i.e. that overflow into the margin. I think the problem has to do with the way LaTeX handles splitting and I seem to remember that there is something that one can insert on a line that turns out too long so that it will be split only if needed. It is something like \allowsplitline.
\documentclass[oneside,oldfontcommands]{memoir} \usepackage[english]{babel} \usepackage[latin1]{inputenc} \usepackage{amsmath} \begin{document} \noindent That is we have that $F_A(\pi_A) = F_A(\pi_{A},B)$ is blablabla if and only if $F_A(\pi_{A, B})(7) = \lambda_{\pi_A}(\varpi_A) =\lambda_{\pi}(\varpi_A) = 11$.
