'
becomes '
and spacing is changed (less around `/', more around `+').
Many of the usual LATEX
constructions can still be used in maths environments but their effect may be
slightly different; eg \textbf{ }
only affects letters and numbers.
`{
' and `}
' are still special characters; they're used
to group characters.
As usual in LATEX you can override
the defaults, but think before doing it: maths support in
LATEX has been carefully thought out
and is quite logical though the LATEX
source text may not be very readable. It's a good idea to write out the formulae
on paper before you start LATEXing, and
try not to overdo the use of the `\frac
' construction; use
`/
' instead.
