How do you type indices on mac?

To type indices on a Mac, you can use the superscript feature. For example, to type "x²," you can highlight the "2," then press "Command + Shift + +" to convert it to superscript. Alternatively, you can use the Character Viewer by pressing "Control + Command + Space," searching for "superscript," and selecting the desired index. For mathematical documents, apps like Pages or Word also have specific options in their formatting menus to insert superscripts.
