During the learning process, we often need to write chemical formulas or equations such as linear and quadratic equations. So how can we write them in Microsoft Word software?
Tutorial on Inserting Exponents, Superscripts, and Subscripts in Word

Below, Mytour will guide you through 3 methods (applicable to Microsoft 2007, Microsoft 2010, and Microsoft 2013):
Method 1: Using Keyboard Shortcuts
-- To write superscripts, simultaneously press: Ctrl+ Shift+ =
For example, to write X3, do the following: Type X, then simultaneously press Ctrl+ Shift+ =, and then type the number 3. To finish writing the superscript, simultaneously press Ctrl+ Shift+ = again.
- To write subscripts, simultaneously press: Ctrl+ =
For example, to write the formula for water, you do the following: Type H, then press Ctrl+ =, type the number 2, and then press Ctrl+ = again (to finish writing the subscript), and finally type O --> you will get the formula as follows: H2O
Method 2:
- Click to select the number you want to create a subscript for
- For subscripts, do the following: Select the number, go to the Home tab, choose Font, in the Fonts window, check the Subscript option

And the obtained result is:

- To create superscripts, select the number, go to the Home tab, choose Font, in the Fonts window, check the Superscript option

And the obtained result is:

Method 3:
- To create superscripts, select X2 as shown:

- If you want to create subscripts, select X2 as shown below:

Note: To select multiple subscripts at once, select the first number, then hold down the Ctrl key and highlight the subsequent numbers you want to subscript.
