G Guest May 24, 2006 #1 Can't find formula to add or subtract two or three entire columns in a spread sheet Thank you
G Guest May 24, 2006 #2 Let's say we have numbers in two columns, column A and column B from rows 1 thru 100. In C1, enter: =A1+B1 and copy down thru C100 Column C will be the sum of columns A & B. To get the grand sum of columns A & B in a single cell, enter in an un-used cell: =SUM(A1:B100)
