It is a very bad idea to make numbers active and to define them in
this way. As an example try to uncomment one of the last lines:
\documentclass {article}
\usepackage {fontspec}
\setmainfont {Linux Libertine O}
\usepackage{tikz}
\begin {document}
Multiply 5 by 7: $7\times 5 = 35$
\catcode `\5 = \active
\catcode `\7 = \active
\def 5{\ifmmode \string 5 \else $5$\fi}
\def 7{\ifmmode \string 7 \else $7$\fi}
Multiply 5 by 7: $7\times 5 = 35$
%\tikz \draw (0,0)--(1,5);
%\section{5 and 7}
\end {document}
