I like to save the class slides and labs on a cis90 memory stick. I want page numbers on my slides so I checked the Power Point help and found that my version of power point will put a page number on the lower right-hand side of each page.
To do this, while viewing the slides, click [b]Header and Footer[/b] on the [b]View[/b] menu and select the [b]Slide number[/b] option. If you would like to save the page numbering, indicate this when you close the file.
