**Summing Formulas**

Summing all cells in a range

It doesn’t get much simpler than this. The following formula returns the sum of all values in a

range named
Data:

=SUM(Data)

The SUM function can take up to 255 arguments. The following formula, for example, returns the

sum of the values in five noncontiguous ranges:

=SUM(A1:A9,C1:C9,E1:E9,G1:G9,I1:I9)

You can use complete rows or columns as an argument for the SUM function. The formula that

follows, for example, returns the sum of all values in column A. If this formula appears in a cell in

column A, it generates a circular reference error.

=SUM(A:A)

The following formula returns the sum of all values on Sheet1. To avoid a circular reference error,

this formula must appear on a sheet other than Sheet1.

=SUM(Sheet1!1:1048576)

The SUM function is very versatile. The arguments can be numerical values, cells, ranges, text

representations of numbers (which are interpreted as values), logical values, array constants, and

even embedded functions. For example, consider the following formula:

=SUM(B1,5,”6”,,SQRT(4),{1,2,3},A1:A5,TRUE)

This formula, which is a perfectly valid formula, contains all the following types of arguments,

listed here in the order of their presentation:

h
A single cell reference

h
A literal value

h
A string that looks like a value

h
A missing argument

h
An expression that uses another function

h
An array constant
