Final answer:
The 6x6 rule for presentations suggests no more than six bullet points per slide and six words per bullet point to prevent information overload.
Step-by-step explanation:
The 6x6 rule is a guideline for creating PowerPoint presentations. This rule suggests that each slide should have no more than six bullet points, and each bullet point should have no more than six words.
This is meant to keep slides clean and information easily digestible, preventing information overload and helping the audience focus on the main points. It encourages presenters to be concise and to use their slides as cues for further elaboration, rather than cramming too much detail into a small space.
