It depends what kind of practical questions you want to post on MS word. I can tell you about some of MS Word diagramming features. MS Word has the ability to create diagrams which you can bring in use to post a practical question. This feature can help you create Cycles, Pyramids, Radial, Venn or even Target diagrams. To use all these, you need to select the option "diagram gallery". There you will find several options available for your layout with previews as to how the diagram will look. If you want to post numeric equations on MS word, the best way to go about it is by using equation editor. With equation editor, you can create numbering and cross referencing equation and later post them on ms word.
