I'm making a spreadsheet of a tabletop game character sheet and I don't want to use multiple cells for the Attack bonus to save space.
Essentially I'm trying to make it end up looking like
I need to input the
=SUM(I21:O21) then take that total and -5, then take that total and -5, then do it once more.
I just need to show each step.
=SUM(i21:021) is 30 it should come out as
How would I do this in a cell?
