Trevor,

Thanks for the quick response. I tried both your suggestions but
unfortunately the results are not

The first example =SUM(C8,F8) returns the value of 0.00

The second example =C8+F8 returns the #VALUE syntax.

Just to clarify, the values I'm working with are -4424.80 (for C8) and
-4,419.28. So the correct answer should be -5.52. (-4424.80 - -4,419.28).
Somehow I can't get Excel to recognize the negative values even though I
formatted the cells as "Numbers" and selected the negative number format.

I appreciate the help.

or just:

The SUM is actually redundant here. You're just trying to *add* two
negative numbers, not taking one away from the other.

Hi~
I'm using Excel 2007 and ran into a problem when creating a formula that
references two cells (C8 and F8) where users will enter a negative number
in
each cell. So for example, the user would enter the following numbers:

Cell C8 ------ -4424.872
Cell F8 ------- -4278.982

To subtract both numbers I created the formula: SUM(C8-F8). But the
problem is that instead of returning a negative number, the result is
shown
as a positive number. I'm not sure why this happening. Could someone
point
me in the right direction?

Thanks for the time and expertise!
