Answer:
During your presentation, the speaker notes are visible on your monitor, but aren't visible to the audience. So the Notes pane is the place to store talking points that you want to mention when you give your presentation.
Add notes while creating your presentation
The Notes pane is a box that appears below each slide. (It is outlined in magenta in the picture below.) An empty Notes pane will prompt you with text that says, Click to add notes. Type your speaker notes there. If you don’t see the Notes pane or it is completely minimized, click Notes on the task bar across the bottom of the PowerPoint window (also marked in magenta in the picture below).
Shows the speaker Notes pane in PowerPoint
If your notes exceed the allotted length of the Notes pane, a vertical scroll bar appears on the side of the pane. You can also enlarge the Notes pane by pointing your mouse at the top line of the pane and then dragging upward after the pointer turns into a double-headed arrow.
