Excel provides no way of adding two cells together directly. The way I usually do it is to convert the numbers to binary (on a paper notepad), add them using twos compliment arithmetic and then convert the answer back to decimal. I then type the sum of the two cells somewhere on the worksheet. I also include a comment saying something like 'Sum of cells A1 and B1' so people will update the cell if A1 or B1 change. :wink:
