Let's say that I have two cells A1 (time needed) and B1 (time spent). I want that when I enter a value in B1 the value of A1 will be reduced automatically. I want that in some way I could enter in A1 the following formula: =A1-B1Is it possible in Google Spreadsheets?
Can I subtract a cell value in another cell that already have one in Google Spreadsheets?
