1. The Function

2. Functions are prewritten formulas. Functions differ from regular formulas in that you supply the value but not the operators, such as +, -, *, or /. For example, you can use the SUM function to add. When using a function, remember the following: Use an equal sign to begin a formula. Specify the function name. Enclose arguments within parentheses. Arguments are values on which you want to perform the calculation. For example, arguments specify the numbers or cells you want to add. Use a comma to separate arguments. Here is an example of a function: =SUM(2,13,A1,B2:C7)

3. The equal sign begins the function. SUM is the name of the function. 2, 13, A1, and B2:C7 are the arguments. Parentheses enclose the arguments. Commas separate the arguments.

10. The IF Function in Excel 2007 The IF function can be quite useful in a spreadsheet. It is used when you want to test for more than one value Syntax: IF(logical_test, value_if_true, value_if_false,) Example: =IF(A1 > 5, "Greater than Five", "Less than Five")

11. Example: =IF(A1 > 5, "Greater than Five", "Less than Five")

12. List of Conditional Operator = Greater than Or Equal To <= Less than Or Equal To <> Not Equal To Another Example: =IF(A1 >= 5, "Greater than or Equal to Five", "Less than Five")

14. The CHOOSE Function in Excel 2007 The Choose function returns a value from a list of values based on a given position. The syntax for the Choose function is: Choose( position, value1, value2,... value29 ) A example of using Choose would be =Choose(1,"Cars","Boats","Planes") - would return Cars =Choose(2,"Cars","Boats","Planes") - would return Boats =Choose(3,"Cars","Boats","Planes") - would return Planes

16. The syntax for the CONCATENATE function is:syntax = CONCATENATE ( text1, text2,... text255 )
