In your debit column (column B?) are you entering negative values, or positive?

If negative:
=A1+B1
and then next row copied down) is:
=A2+B2+C1

If positive:
=A1-B1
and then next row (copied down)
=A2-B2+C1

Variations for cleanliness:
=IF(COUNT(A2:B2)=0,"",A2-B2+C1)
This would display a blank cell if not entry has been made yet.

I would like to add 2 columns and display the results in a 3rd column and
keep a running balance. A "check" register is really what I would like to
set up.

Would I write the function in the "c" column for example?
=sum(A1+B1)

then for the next row that the info will go into cell C2
=sum(C1+A2+B2)

I was wondering how to write out the function so that I don't have to do it
for each cell. Something like a variable N?
