How do i add the sum of a column in excel?

Excel has a built in sum function to calculate the sum of elements. The syntax of this function is:

=sum (argument)

This formula is written in the destination cell where we need our sum to show up.

The argument is the cells, columns or range of cells and columns for which we need to find the sum. If we need to find the sum of elements in a column, the formula will be like:

= sum (A:A)

This formula will find the sum of all elements that are present in the column A. The argument in the above formula is A:A which represents that entire column A is selected.

This formula can be modified according to the needs. For example, if we need to find the sum of two columns A and B, the formula will be:

=sum (A:B)

This formula calculates the sum of all elements in columns A and B.
