When you insert Slide Numbers on your slides, you may discover that the location of the Slide Number changes depending upon the active Theme of your presentation. Some Themes (or templates) may display the Slide Number at the bottom right — with other Themes, it may be located at the top right, or even the bottom center. As you can observe, the location of the Slide Number may seem to be influenced by the Theme or template — and that’s almost true. However it’s only the Slide Master within your Theme or template that’s influences the position of your Slide Numbers.
