Word has had both these features for 10 years now. > Is Microsoft Word able to break the line automatically in a long sum? Yes. It can automatically infer alignments for broken equations too, something TeX cannot do. > Is Microsoft Word able to stretch the spaces around the + sign in the math formula to better suit the justified alignment of the paragraph? Yes. It can also stretch within nested math items, such as \left\right brackets, which TeX cannot do.
