When editing chemistry and mathematics data, we often use superscript or subscript to represent special symbols. Take this document as an example, m2 represents the square in the unit area. How can we set the number 2 as a superscript? Select the number 2. In the amp;quot;Homeamp;quot; tab, click the amp;quot;Superscriptamp;quot; button. Or we can use the shortcut key amp;quot;Ctrl+Shift+=amp;quot; to set the number as a superscript. Numbers in some chemical symbols need to be set as subscripts, such as O2, N2. Select the number 2 in O2. In the amp;quot;Homeamp;quot; tab, click the amp;quot;Subscriptamp;quot; button, or use the shortcut key amp;quot;Ctrl+=amp;quot; to set the number as a subscript display. In addition, after clicking the right mouse button, click amp;quot;Fontamp;quot; in the shortcut menu bar, and a dialog box will pop up. You can also set amp;quot;Superscriptamp;quot; or amp;quot;Subscriptamp;quot; in amp;quot;Effectsamp;quot;.
