Each PowerPoint presentation contains several slides. Let’s compare each slide to a blank canvas or an empty sheet of paper! You can thereafter add content to the slides in much the same way as you use brushes to create strokes of paint, or a pen to write. For example, do you want some text? Then you must add a text box. Want a picture? Just insert a picture and place it anywhere on your slide! Wait, this is not really the proper way to work in PowerPoint! Unlike a new canvas or a blank sheet of paper, PowerPoint does not like to provide you so unstructured freedom, and this can be good in many ways. Primarily, PowerPoint structures each slide you create into one of its prescribed layouts.
