If you are using Mathematica through the notebook front end, the default input format type is StandardForm. You can change the the default input format type to InputForm by selecting InputForm in the Default Input Format Type submenu of the Cell menu, or you could introduce your own typesetting rules to get the analogous behavior in StandardForm.
