Equal to                        =        = A1 = B1    The formula returns TRUE if a value in cell A1 is equal to the values in cell B1; FALSE otherwise.
Not equal to                    <>        = A1 <> B1    The formula returns TRUE if a value in cell A1 is not equal to the value in cell B1; FALSE otherwise.
Greater than                    >        = A1 > B1    The formula returns TRUE if a value in cell A1 is greater than a value in cell B1; otherwise it returns FALSE.
Less than                        <        = A1 < B1    The formula returns TRUE if a value in cell A1 is less than in cell B1; FALSE otherwise.
Greater than or equal to       >=        = A1 >= B1    The formula returns TRUE if a value in cell A1 is greater than or equal to the values in cell B1; FALSE otherwise.
Less than or equal to           <=        = A1 <= B1    The formula returns TRUE if a value in cell A1 is less than or equal to the values in cell B1; FALSE otherwise.
