`@math': Inserting Mathematical Expressions
===========================================

  You can write a short mathematical expression with the `@math'
command.  Write the mathematical expression between braces, like this:

     @math{(a + b)(a + b) = a^2 + 2ab + b^2}

This produces the following in Info:

     (a + b)(a + b) = a^2 + 2ab + b^2

  The `@math' command has no effect on the Info output.  Currently, it
has limited effect on typeset output.  However, this may change since
TeX itself is designed for mathematical typesetting and does a splendid
job.

  Certainly, for complex mathematical expressions, you could use TeX
directly.  See Using Ordinary TeX Commands: Using Ordinary TeX Commands.  When you use TeX directly, remember to write the
mathematical expression between one or two `$' (dollar-signs) as
appropriate.
