REMARKS

* For an illustrated example refer to the page under Advanced Functions
* This function includes hidden cells.
* Arguments that are just numbers are included.
* Arguments that are just numbers passed as text ("3") are included. See Example 15.
* Arguments that are just logical values are included. True evaluates to 1. False evaluates to 0. See Example 18.
* Arguments that are just text will generate a #VALUE! error. See Example 16.
* Arguments that are references to empty cells are excluded. See Example 8.
* Arguments that are references to cells containing zeros are included. See Example 9.
* Arguments that are references to cells containing dates are included and the date serial number is used. See Example 12.
* Arguments that are references to cells containing logical values are excluded. See Example 11.
* Arguments that are references to cells containing text are excluded. See Example 10.
* Arguments that are arrays containing logical values are excluded. See Example 20.
* Arguments that are arrays containing text are excluded. See Example 17.
* If any cell references contain an error, then that error is returned. See Example 14.
* You can have a maximum of 255 arguments.
* To sum all the values in column "C" use: "=SUM(C:C)". This function automatically finds the last used row in a column reference.
* There is also an AutoSum button to help you enter this function quickly.
* You can use the SUMIFS function to satisfy multiple conditions.
* You can use the SUMPRODUCT function to return the sum of the product of one or more arrays of values.
* You can use the SUMSQ function to return the sum of the squares of all the values in a list, table or cell range.
* You can use the AGGREGATE function to exclude hidden cells.
* You can use the SUMFORMAT to return the sum of all the values that have been formatted with multiple attributes.
* You can use the SUMVISIBLE - User Defined Function to exclude hidden cells.
* This is similar to the AVERAGE, COUNT, MAX and MIN functions.

1 - What is the sum of 2 and 4.
2 - What is the sum of 5, 10 and 15.
3 - What is the sum of 5, 10, 15 and 0. Zeros are always included.
4 - What is the sum of -2, -3, 4, 5 and 6.
5 - What is the sum of the values in the array (-2, -3, 4, 5, 6).
6 - What is the sum of the values in range "B1:B3".
7 - What is the sum of the values in range "B1", "B2" and "B3".
8 - What is the sum of the values in range "B1", "B2", "B3" and "B4". B4 is empty. Empty cells are always excluded.
9 - What is the sum of the values in range "B1", "B2", "B3" and "B5". B5 is zero so this gets included.
10 - What is the sum of the values in range "B1", "B2", "B3" and "B6". B6 is text so this gets excluded.
11 - What is the sum of the values in range "B1", "B2", "B3" and "B7". B7 is a logical value so this gets excluded.
12 - What is the sum of the values in range "B1", "B2", "B3" and "B8". B8 is a date so this gets included as a date serial number.
13 - What is the sum of the values in the named range that refers to the range "B1:B3".
14 - What is the sum of the values in range "B5", "B6" and "B9". B9 contains an error so that gets returned.
15 - What is the sum of 2 and "2". Text values that are actually numbers are included.
16 - What is the sum of 2 and "some text". Text values passed as arguments are excluded.
17 - What is the sum of the values in the array (2, "some text"). Text values inside arrays are excluded.
18 - What is the sum of 2 and TRUE. Logical values passed as arguments are included.
19 - What is the sum of 2 and FALSE. Logical values passed as arguments are excluded.
20 - What is the sum of the values in the array (2, TRUE). Logical values inside arrays are excluded.
