I want to subtract two numbers. The numbers are categorized, e.g. cell N2 (WAS) and N3 (IS). The cells populated are N1 thru N351. I want to calculate the difference between the two cells. If the N2 (WAS) cell is less than the N3 (IS) cell, e.g. N2 < N3, then it is a positive number. If N2 (WAS) cell is greater than the N3 (IS) cell, then it is a negative number. If the two cells are equal then the result would be 0.


(WAS) Row 2-----N2 = 346.18-----(IS) Row 3-----N3 = 347.00-----M3 = 0.82

(WAS) Row 4-----N4 = 484.00-----(IS) Row 5-----N5 = 483.50-----M5 = -0.50

(WAS) Row 6-----N6 = 22.75-----(IS) Row 7-----N7 = 22.75-----M7 = 0.00

Rows go from 2 thru 351.

In M2, insert the following formula and fill down ...


This will put nothing into every even numbered row. In every odd numbered row it will put the difference you need.

Enter =N3-N2 into cell M3.  Then select cells M2 and M3, and drag down:
