Inline functions would require some rather sophisticated VBA coding to
ensure that parsing worked correctly, and there are very few
respondents in these newsgroups who have any experience writing
lexical analyzers or parsers who could provide support in
development.

Better to be more forthright: Excel can't do this without a lot of
agonizing programming, and even then the results will be less than
satisfactory. If the OP wants math software functionality, the OP
should use math software, not Excel. Perhaps siag (a linux/unix
spreadsheet implemented in Scheme, this the name - Scheme In A Grid)
would provide this, but it's the only one I can think of that might
be able to.
