Dynamic Subtraction formula in excel sheet

Question

I need to write a formula in excel for dynamic subtraction which subtracts a cell(of a specified column) from the cell just above it.

For example, A2 = A1 - G

Answer 1

Excel is smart enough to use a dynamic reference and relative reference to the current cell. For example if you put =A1-G1 in cell A2 and use the square to drag this cell down, you will automatically get the similar formula in all others in column A.
