I know that
amsmath package provides extra math spacing commands, like the followings
\thickspace, there are corresponding negative space as well like
\negthickspace. But from the package documentation, it says:
For the greatest possible control over math spacing, use \mspace and ‘math units’.
Besides I tested out that anywhere the
\mspace command takes effect then the
\hspace command takes effect as well. I was wondering what's the difference between these two commands when used in math mode? If there's no difference between them why would I bother using
\hspace is more often used.
Any hints or help on this will be greatly appreciated!
