Adding and Sustracting

[Guest]

I need a double formula if that's possible.
1 Worksheet A,B,C,D from 1 to 100 all columns.
For explanatories purposes I ll use just the first row ( formula will be
copied down to 100)
D1=A1+B1
but if there is not value in B1, then it will be a value in C1 and the
formula instead of adding will sustract.>> D1=A1-C1
A1 will always has a value
B1 and C1 will alternate ( one of the 2 is empty while the other has a value)
D1 will be the total, either from adding B1 or sustracting C1( depending who
has the value) from A1.

You need an IF function, like

=IF(B1="",A1+B1,A1-C1)

Thanks for the formula, but it did not meet the requirements. I know is
almost that one but can not make it up!!!
Thanks for repling.

Either of these

=IF(B1<>"",A1+B1,A1-C1)

=IF(B1="",A1-C1,A1+B1)

B1 and C1 will alternate ( one of the 2 is empty while the other has a
value)

If that is the case then and the cells are truely empty not just showing an
empty string then:

=A1+B1-C1

will work because the empty cells will be treated as zero values.
