If you want a particular ordering (etc) of terms for a document, I suggest you learn how to use the editor (for you, Word's equation editor, I guess), to move things around, change fonts, etc. You can try to thwart Mathematica's notions of evaluation, simplification, display, but it is like teaching a pig to sing. {=93Never try to teach a pig to sing; it wastes your time and it annoys the pig.=94 (Robert Heinlein)}
