math spaces

List of predefined spaces:

Math Spaces
Command	Example	Result
\, (smallest predefined)	$$$a\,b$$$	$$a\,b$$
\: (second smallest predefined)	$$$a\:b$$$	$$a\:b$$
\; (third smallest predefined)	$$$a\;b$$$	$$a\;b$$
\/ (avoiding ligatures)	$$$V\/A$$$ instead of $$$VA$$$	$$V\/A$$ instead of $$VA$$
\quad (space of current character set size)	$$$a\quad~b$$$	$$a\quad~b$$
\qquad (double space of current character set size)	$$$a\qquad~b$$$	$$a\qquad~b$$
\_ (where _ is blank!)	$$$a\ b$$$ (whereas $$$a\b$$$ is not a valid filter expression since the blank space is missing; it is recommended to use the tilde ~ instead of the simple whitespace)	$$a\ b$$
\hspace{n} ,where n positive integer (= n Pixels)	$$$a~\hspace{30}~b$$$ $$$a~\hspace{15}~b$$$ $$$a~\hspace{2}~b$$$ $$$a~\hspace{1}~b$$$	$$a~\hspace{30}~b$$ $$a~\hspace{15}~b$$ $$a~\hspace{2}~b$$ $$a~\hspace{1}~b$$
\unitlength{m}\hspace{n}, changes the default unit length (m=1px) to be applied	$$$a~\hspace{2}~b\unitlength{10}~\hspace{2}~c$$$ (second space is 10x2=20px)	$$a~\hspace{2}~b\unitlength{10}~\hspace{2}~c$$

Note: Simple blank spaces and tildes (~) are ignored by the TeX filter and don't produce any space. You must use one of the defined math spaces to get a visible (extra) space.
