tains zero as an interior point, then the result AB and A=B is expressed by only three
of the four bounds of A and B. In all these cases (3, 6, 7, 8, 9) in Table 4.1, the bound
which is missing in the expression for the result can be shifted towards zero without
changing the result of the operation A B. Similarly, in cases 5 and 6 in Table 4.2,
the bound of B, which ...
