First approach:

x - 1 // TraditionalForm

4 (1 - q) // TraditionalForm

If you do math with the results, you may have to apply TraditionalForm  
again (and again) ((and again)).

(second) Use menu options Cell>Convert to>Traditional form or the key  
sequence Shift-Command-T to format a cell in traditional form.

(third) I believe you can also set the default output (and input) format  
to TraditionalForm, but I have no idea how... and I think you won't always  
like the result. Documentation doesn't make it easy to find this, so I  
haven't.

(fourth) You can use a style sheet that implements the third option.
