A series of lines marked up by \[...\\...\]
may be divided into
2 or 3 left-aligned columns by inserting &
characters in each
line. The result is as if one had used an explicit tabular
or
array
environment (according to the current mode) with the
argument @{}l@{}l@{}l@{}
. Note that no space at all is
inserted between the columns. In text mode, one may use e.g.
~&~
to get space between columns; in math mode, the correct
spacing around binary operations and relations can be obtained by
inserting {}
for arguments that have been separated by
&
s.
