Additions are ok, it's subtraction when they might be close in value that is deadly.

  additions arent strictly ok. if the two addends arent close together in magnitude, then one of them is going to lose some bits

    The result won't be far off from the correct answer, however.

      Consider (A+B)-A, where A>>B.

        That has a substraction where the 2 values are nearly equaly, which is the dangerous op as I said.
