There are various wrappers that you can use to control the way Mathematica
expressions are formatted which you can find one the Cell | Display As...
menu item. The one you want is TraditionalForm which you can use in-line
thus:
Sum[a^k, {k, 0, M}]//TraditionalForm
If you want to wrap all of your outputs in TraditionalForm then you can do
the following:
$PrePrint=TraditionalForm[#]&;
in which case Sum[a^k, {k, 0, M}] (and everything else) will be
traditionally formatted.
