    summation problem.

    Every time I try to write a sum or prod. in latex I get something like this: http://data.artofproblemsolving.com/...c0e633e009.png

    any help on how to make the notation correct?

    If this is in a LaTeX document try $$ .. $$ as the mathmode delimiters (makes what is enclosed a display equation), if on MHF (and in a LaTeX document for that mater) start the math string:

    [tex]\displaystyle ... [/tex]
