• \; (backslash semicolon) inserts the third smallest predefined space in a formula
• Equivalent: \hspace{6}
• Ex.: $$a\;b$$ gives $a\;b$
• Ex.: $$a~\hspace{6}~b$$ gives also $a~\hspace{6}~b$

• \: inserts the second smallest predefined space in a formula
• Equivalent: \hspace{4}
• Ex.: $$a\:b$$ gives $a\:b$
• Ex.: $$a~\hspace{4}~b$$ gives also $a~\hspace{4}~b$

• \/ (backslash slash) avoids ligatures
• Ex.: $$V\/A$$ gives $V\/A$ in contrast to $$VA$$ which gives $VA$

• In order to prevent some browser specific problems with whitespaces, it is advisable to use ~ (tilde) as the whitespace instead of the normal blank key (in places where whitespaces are mandatory, e.g. after commands).
• Ex.: $$\frac~xy$$ to produce $\frac~xy$
• Ex.: $$\sqrt~n$$ to produce $\sqrt~n$

• inserts a space of n pixels
• Ex.: $$f(x)\hspace{6}=\hspace{6}0$$ gives $f(x)\hspace{6}=\hspace{6}0$
• can be combined with the preceding command \unitlength{m}(default: m=1px) , which defines the applied unit
• Ex.: $$\unitlength{20}a\hspace{2}b$$ gives $\unitlength{20}a\hspace{2}b$ , i.e. a space of 20x2=40px

• inserts a double space of current character set size
• Ex.: $$a\qquad~b$$ gives $a\qquad~b$

• inserts a space of current character set size
• Ex.: $$a\quad~b$$ gives $a\quad~b$

List of predefined spaces:

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.
