One method, due to Jean-Marc Gulliet (see link 1 below), uses the undocumented Polynomial Form 4 (1 - q) // PolynomialForm[#, TraditionalOrder -> True] & The reply of Jens-Peer Kuska given in the second link below may also be of interest. http : // forums.wolfram.com/mathgroup/archive/2008/Oct/msg00016.html http://forums.wolfram.com/mathgroup/archive/2008/Oct/msg00019.html On Sun, Sep 18, 2011 at 9:11 AM, Ralph Dratman <ralph.dratman at gmail.com>wrote: > > I feel like a small child asking this, but how can I get Mathematica to say > (x - 1) instead of (-1 + x), or to give me > > 4 (1 - q) > > instead of the doubly annoying > > -4 (-1 + q) ? > > In brief, given the choice, I prefer to look at subtraction rather than > negation.
