9.4.12 Mathematical Spacing
LaTeX deals with mathematical spacing fairly well, but sometimes you may find you want to adjust the spacing yourself. Available spacing commands are listed in Table 9.15.
Command  Example Input  Example Output 

$AB$ 

\thinspace or \, 
$A\,B$ 

\medspace ^{†} or \: 
$A\:B$ 

\thickspace ^{†} or \; 
$A\;B$ 

\quad 
$A\quad B$ 

\qquad 
$A\qquad B$ 

\negthinspace or \! 
$A\!B$ 

\negmedspace ^{†} 
$A\negmedspace B$ 

\negthickspace ^{†} 
$A\negthickspace B$ 

Exercise 24: More MathematicsThis exercise uses the spacing command
\qquad

and ellipses symbols. It also redefines the\vec
command, as was done in the previous section, uses the bmatrix environment (see §9.4.10. Arrays), and has subscripts and superscripts.Try to reproduce the following output:
