I have been attempting to write a math book in Microsoft word. I have 2010 and the Mathematics add-on. When I try to print it off it prints just every math equation i added in is left out but there is space for them

does anyone know why this is happening. I would like to be able to go over this/write more at school but I would like to be able to see what I've done so far to do that. thank you for any help you might give
