Adding superscript or subscript text isn't just for mathematicians or physicists. Referenced notes, footnotes and symbols are often in a superscript format. Whenever you need text to fly a bit above ordinary words, you can change it to superscript in the Font dialog box. If you're adding a footnote or a trademark symbol, Word 2013 presents the number or symbol in superscript automatically.
Adding Superscript or Subscript
Highlight any word, letter or even an entire paragraph that you want formatted in superscript.
Click the "Home" menu, then click the small "Dialog Box Launcher" in the bottom right corner of the Font group to open the Font dialog box.

Click the "Superscript" check box to change the highlighted text. If you want to format the text in subscript, check the "Subscript" check box. You can also change the font style or font size for the highlighted text, if desired.
Click "OK" to close the Font dialog box. Continue working on your document.
Adding Symbols, Equations or Footnotes
Place the cursor where you want to enter a symbol or equation. Click the "Insert" menu and then the "Symbol" icon. To add a symbol such as a copyright or trademark, click the "Symbol" icon in the drop-down menu. If you click the "Equation" icon, you can enter an equation manually. Clicking the "Arrow" beneath the Equation menu gives you a variety of common equations that are already formatted with superscript or subscript where required.
Add a footnote at the bottom of the document by clicking the "Reference" menu and then selecting "Insert Footnote." A numbered footnote is added to the page's footer, with a corresponding number in superscript where the cursor was placed.
Type your footnote. The cursor is automatically placed in the footer when you click the "Insert Footnote" icon. If you add additional footnotes, they are numbered sequentially in the document section. For example, if you have two footnotes on page one, the footnotes on page two will begin with footnote "3."
