 Formula Description =NOT(A2>100) A2 is NOT greater than 100 =IF(AND(NOT(A2>1),NOT(A2<100)),A2,”The value is out of range”) 50 is greater than 1 (TRUE), AND 50 is less than 100 (TRUE), so NOT reverses both arguments to FALSE. ANDrequires both arguments to be TRUE, so it returns the result if FALSE. =IF(OR(NOT(A3<0),NOT(A3>50)),A3,”The value is out of range”) 100 is not less than 0 (FALSE), and 100 is greater than 50 (TRUE), so NOT reverses the arguments to TRUE/FALSE. ORonly requires one argument to be TRUE, so it returns the result if TRUE.
