In earlier version of Microsoft Office (Word 2003), trying to write a subscript or superscript takes quite a time but with the new Word 2007 it’s so simple. For those who are writing technical articles face situation to use these subscripts and superscripts in almost every article like mathematical formulae or chemical equations.
What are Subscript and Superscript? A subscript appears smaller and below the baseline (Ex. H2O or X2) while a superscript appears smaller and above the baseline (Ex. X3)
