Adding Page Numbers in Microsoft Word

• In general, unless otherwise instructed, page numbers should appear at the bottom-right of your page (in what's called the 'footer').
• Using the software's Page Number feature will put page numbers in the correct place.

Choose 'Insert' from the toolbar

From 'Insert,' choose 'Page Numbers'

The default will be to insert page numbers in the bottom-right of the page. Choose this, and your pages will be set.
