f

#### (x - 1) or (-1 + x)

```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)

-4 (-1 + q)  ?

In brief, given the choice, I prefer to look at subtraction rather than
negation. The binary operator instead of the unary.

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.

The general problem of forcing expressions to appear in a required form
can be quite tricky, but using TraditionalForm will solve this case:

In[105]:= x - 1 // TraditionalForm
