I have a WORD2003 table -- with 4 columns (A, B, C, and D) and 500 rows --
with numbers in each cell in Columns A and B. How can I show the SUMs (An +
Bn) in Coulmn 3 and the DIFFERENCEs (An - Bn) in Column 4?

Is there a way to do all the 500 sums (or differences) with just a few
keystrokes or do I have to repeat the basic calculation 500 times?

Thanks. ...wdc
