                               Logical_test is any value or expression that can be evaluated to true or  Notes
                               alse.
                               Value_if_true is the value that is returned if iogical_test is true.
                                 Value_if_false is the value: that is returned if logical_text is false.

                               Up to seven IF functions can be nested as value_if_true and value_if_false
                               arguments to construct rnore elaborate tests. The  result values can display
                               text with an argument such as “Hello”,  calculate a formula such as B12*6
                               or display the contents of a cell such as D35. Consider the following
                               formula
                               lF(834>5O, 834*2, “Entry tool low!”)
                               ln this example, the IF( )funcion prociucesthe answer 110 if B34 is 55.
                               lf B34 is 12, however, the celi that contains the function display the text
                               given below.
                               Entry too low!

                 AND           The AND function joins test conditions. Returns TRUE if all its logical
                               arguments are TRUE; returns FALSE if one or more logical  arguments is
                               FALSE.

                               Syntax:  AND(logical’1, logical2...)
                               AND(TRUE, TRUE) returns TRUE.
                               AND(TRUE, FALSE) returns FALSE.
                               AND(2+2=4 ,2+3:5) returns TRUE.

                 OR            Returns TRUE if any argument is TRUE.
                               Syntax: OR(logical1 ,logical2, ...)

                               Logical1 , logical2, ... are 1 to 30 conditions you want to test that can be either
                               TRUE or FALSE.
                               OR(1 +1:1, 2*2:5) returns FALSE.

                               lf A1:A3 contains the values TRUE, FALSE and TRUE, then
                               OR(A1:A3) returns TRUE.
                 NOT           Reverses the logic of its argument.

                               Syntax:  NOT(logical)
                               NOT(FALSE) returns TRUE.
                               NOT(1 +1=2) returns FALSE.

                 10.8.4 Mathematical and Trigonometric Function
                 Mathematical and trigonometric functions provide the foundation for the majority of
                 worksheet calculations. Most scientific and engineering functions are found under
                 mathematical functions.
                 ABS:          The ABS function returns the absolute value of a number.
                               Syntax:  ABS(number) Number is the real number for which you want the
                               absolute value.
