To see all the slides on one screen in Microsoft PowerPoint, you should use the Slide Sorter view.

Explanation:

1. Slide Sorter view allows you to see thumbnail previews of all slides in the presentation at once, enabling easy navigation and organization of slides.
2. In contrast, Reading view is designed for presentation mode, Notes Page view shows one slide along with its associated notes, and Outlines view displays the text content of slides in a hierarchical format, which doesn't show the slides themselves.

Using Slide Sorter view is beneficial for arranging slides, making bulk edits, or reviewing the overall flow of your presentation efficiently.
