Ooops. Fingers slipped. Corrected formula: =A3-SUM(C1:C39) Use colon,
not minus sign for range.

I have a number in a cell A3 and about 40 numbers in 40 other cells that I
want to subtract from the number in A3. I tried = A3-C1:C39 but that did not
work.

What is the easiest and correct way to perform this calculation?

Thanks
