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. The binary operator instead of the unary. I'm not asking Mathematica to read my mind about the way I want every possible expression to look, rather I am hoping to find out how to transform something I don't like into something I like, in a way that is guaranteed not to change the value of the expression.
