Question: Express results using symbolic summation

Hi all,

I've searched all over, and I can't figure this out: I'm hoping to have a result expressed in symbolic notation.  For example, if my result is x_1+x_2+...+x_n, how can I have maple express this answer as summation of x_i i=1 to n.

I actually have a matrix, each element of which is a ratio of summations.  In order to more easily comprehend it, I'm hoping to view it in summation notation.

 

Thanks,
