The range for 6-bit ones' complement is -32 < x < 32 and
2^5-2 = 30 is represented by itself.

30 + 30 = 60 is not representable; i.e., the addition
overflows.

Correspondingly, when we add the representative of 30 to
itself and normalize, we get 29, the representative of
29, which is not the sum of 30 and 30.
