IF

IF(logical_test [,value_if_true] [,value_if_false])

Returns the value based on whether a condition is True or False.

logical_test	The value or expression that can be evaluated to True or False.
value_if_true	(Optional) The value that is returned if "logical_test" is True.
value_if_false	(Optional) The value that is returned if "logical_test" is False.

REMARKS

* For an overview of conditional formulas refer to this page
* This function is not case sensitive when matching text strings.
* This function does not support wildcards (? and *).
* This function does use short circuiting evaluation.
* If the "value_if_true" is left blank then, "value_if_false" must be provided.
* If the "value_if_false" is left blank then, "value_if_true" must be provided.
* If "logical_test" is true and "value_if_true" is blank, then zero is returned. Example 12.
* If "logical_test" is false and "value_if_false" is blank, then False is returned.
* You can have a maximum of 64 nested IF functions.
* You can use the IFERROR function to return the value or something else if it evaluates to an error.
* You can use the IFNA function to return the value or something else if it evaluates to #N/A.
* You can use the IFS function when you have multiple conditions and do not want to use nested IF functions.
* You can use the AND function to return the logical AND for any number of arguments.
* You can use the OR function to return the logical OR for any number of arguments.
* You can use the NOT function to return the opposite of a True or False value.
* You can use the SWITCH function to return a value based on a list of exact matches.

1 - What value is returned when the logical test returns True.
2 - What value is returned when the logical test returns False.
3 - What value is returned when the logical test "B2>20" is evaluated.
4 - What value is returned when the logical test "B2<30" is evaluated.
5 - What value is returned when the condition "text"="text" is evaluated.
6 - What value is returned when the condition "TEXT"="text" is evaluated. This function is not case sensitive.
7 - What value is returned when the cell "B6" is compared to an empty string.
8 - What value is returned when the cell "B6" is passed to the ISBLANK function.
9 - What value is returned when the AND function is evaluated.
10 - What value is returned when the OR function is evaluated.
11 - What value is returned when the logical test is True and the "value_if_false" is not provided.
12 - What value is returned when the logical test is True and the "value_if_false" is not provided. The default value is 0.
13 - What value is returned when the logical test is False and the "value_if_false" is not provided. The default value is False.
14 - What value is returned when the logical test is True but the "value_if_true" is blank. The default value is 0.
15 - What value is returned when the logical test is False but the "value_if_false" is blank. The default value is False.
16 - What value is returned when the logical test is True and both the other arguments are blank. The default value is 0.
17 - What value is returned when the logical test is False and both the other arguments are blank. The default value is 0.
18 - What value is returned when the cell "B2" is evaluated using multiple nested IF functions.
19 - What would the equivalent formula be using the IFS function.
20 - What value is returned when the cell "B4" is evaluated using multiple nested IF functions.
21 - What would the equivalent formula be using the IFS function and the ISTEXT function.
22 - What would the equivalent formula be using the SWITCH function.
