Re: Replacing expressions with smaller atoms


one way would be to use a local rule like L:>(x^2+x+1). Your L then does not
have a global value, you use it in your expression until you want to
substitute it with x^2+x+1, then you just use (your

It would be easier to answer your question if you'd provide more information
about your problem/goals.
