Those numbers are just sums from other records in my table that I calculate with a counting field. I didn’t include much more information, because I’m trying to learn how to do something generic…that I would like to do in various circumstances:
To subtract two values in the same Field.
i.e. if I have a blank table with only two values (say 21 and 1) in the same number Field, how could I subtract them?
It sounds like you need a spreadsheet. if so, you can always use a tool like Make.com to send your data from Airtable to Google Sheets or Microsoft Excel, and then you can do your spreadsheet functions there.
