[Staffan Ringbom]

Try the following simple thing

Insert:

in the latex preamble


then in the matheditor type:
 \mathbb{R}   or
\mathbb{N}   or
\mathbb{C}   or
\mathbb{Q}   or
\mathbb{Z}


best,

Staffan


P.S. I've found "The (not so) short quide to LaTeX - or LaTeX in 89 minutes"
useful
It can be found from several places e.g. via www.tug.org.
