Hi Alsaeh,
in C1 enter

=A1+B1

then copy formulas down

If you want to have a total of column C at the bottom enter

=sum(C1:C1000)

change range to fit your needs

Ed,
I want to sum cells in Col A + cells in Col B, then store the result
in cells of Col C, respectively.
So, A1+B1=C1
A2+B2=C2

The way I wish to do it is to store a single formula in any place (May
be in C1) then have it automatically sum any numbers in A2, add it to
B2, store the result in C2.
