Another play to try ..

Assume source data is in col A, from A1 down

Put in B1:
=IF(A1="","",IF(ISNA(MATCH(-A1,A:A,0)),ROW(),""))

Put in C1:
=IF(ISERROR(SMALL(B:B,ROWS($A$1:A1))),"",INDEX(A:A ,MATCH(SMALL(B:B,ROWS($A$1
:A1)),B:B,0)))

Select B1:C1, fill down until the last row of data in col A

Col C should return the required results, neatly bunched at the top

(above assumes the +/- number cancellations within the column
are exactly in pairs)

...
I have a total column that contains several positive and negative numbers
that offset one another. Example:
Total
123
523
153
-523
-123
Is there a way to write a formula so that excel will delete all the
numbers
that wash each other and leaves only numbers that are stand alone. From
the
example above it will be $153. Please help ASAP. I have a big worksheet
that
has well over 1,000 roles of mixed numbers that I need to delete. Thank
YOu,
