You can add Slide Numbers and Date and Time to your PowerPoint presentation to make it more impressive, and this post shows how to do that.

Whether you're formatting or changing existing page numbers or adding them and then formatting them, PowerPoint 2007 gives you full control over how they appear.

In PowerPoint 2010, page numbers are called "slide numbers." To remove slide numbers from an entire PowerPoint 2010 presentation or from a single slide, you must use the Slide Number tool.
