LaTeX space commands

LaTeX ignores your typing spaces. It's common to use \ to fill a space in the texts or equations but the length of it may be wide or narrow in some contexts. The below commands will help you to make beautiful LaTeX documents.

$\begin{array}{|l|l|} \hline \verb|ab| & ab \\ \verb|a b| & a b \\ \verb|a\ b| & a\ b \\ \verb|a\ b| & a\ b \\ \verb|a\ \ b| & a\ \ b \\ \verb|a\quad b| & a\quad b \\ \verb|a\qquad b| & a\qquad b \\ \verb|a\ b| & a\ b \\ \verb|a\,b| & a\,b \\ \verb|a\:b| & a\:b \\ \verb|a\;b| & a\;b \\ \verb|a\!b| & a\!b \\ \hline \end{array}$
