I am not sure if evaluate( )-mathod will do non-numeric evaluations. I see that your mathml is non-numeric in nature (I mean symbolic).

This is the output I get if I use Mathematica to interpret your mathml. I am also trying to use JSci to convert mathml to Jsci objects. Can you send me an example code if you have any?? I couldn't understand how to use MathMLDOMimpl library.

You have to send this information to a solver to get the calculation made.But a MathML equation just with <times/>, <plus/>, <minus/>, ... can be computed with the evaluate()-method. Am I wrong or is the computation of <sum/> missing?
