Is it possible to have numbers added to the same cell and have excel continue
to calculate the addition for me in that same cell......ex: I have the number
8 in cell d2 and I want to add the number 8 to that cell and have excel add
the 8 to the previous 8 for a total of 16 in the same cell.....the next time
I would add 5, and the total would be 21? Can this be done in a single cell?
