Abstract: The paper gives a necessary and sufficient condition for the norm equality $\parallel S-T\parallel =\parallel S\parallel +\parallel T\parallel$ of bounded linear operators and . The invertibility of an operator which is related to the norm equality is discussed. Some new results about the unilateral shift are given.
