Functions Browser
In Numbers, you use the Functions Browser to learn about and insert functions to perform calculations in your spreadsheets.
To open the Functions Browser, select a table cell, then type the equal sign (=). The formula editor appears in the table cell and the Functions Browser opens on the right side of the window (if you don’t see it, tap in the toolbar).
