Excel formula for editor and tutorial

Show All Testing whether conditions are true or false and making logical comparisons between expressions are common to many tasks. You can use the AND, OR, NOT, and IF function to create conditional formulas.
The IF function uses the following arguments.
Formula with the IF function
 logical_test: The condition that you want to check.
 value_if_true: The value to return if the condition is true.
 value_if_false: The value to return if the condition is false.
What do you want to do?
Create a conditional formula that results in a logical value (TRUE or FALSE)
Create a conditional formula that results in another calculation or in values other than TRUE or FALSE
Create a conditional formula that results in a logical value (TRUE or FALSE)
To do this task, use the AND, OR, and NOT functions, and operators .
Example

Formula Description (Result)
=IF(A2=15, "OK", "Not OK") If the value in cell A2 equals 15, then return "OK". (OK) =IF(A2<>15, "OK", "Not OK") If the value in cell A2 is not equal to 15, then return "OK". (Not OK) =IF(NOT(A2<=15), "OK", "Not OK") If the value in cell A2 is not less than or equal to 15, then return "OK". (Not OK)
=IF(A5<>"SPROCKETS", "OK", "Not
OK")
If the value in cell A5 is not equal to "SPROCKETS", then return "OK". (Not OK)
=IF(AND(A2>A3, A2
OK")
If 15 is greater than 9 and less than 8, then return "OK". (Not OK) =IF(AND(A2<>A3, A2<>A4), "OK", "Not
OK")
If 15 is not equal to 9 and 15 is not equal to 8, then return "OK". (OK) =IF(OR(A2>A3, A2
OK")
If 15 is greater than 9 or less than 8, then return "OK". (OK) =IF(OR(A5<>"Sprockets",
A6<>"Widgets"), "OK", "Not OK")
If the value in cell A5 is not equal to "Sprockets" or the value in cell A6 is not equal to "Widgets", then return "OK". (Not OK) =IF(OR(A2<>A3, A2<>A4), "OK", "Not
OK")
