E (padded with zeros) is logically anded with A, bit by bit.

E (padded with zeros) is logically ored with A, bit by bit.

A is loaded with E (padded with zeros).

A is loaded with the one's complement of E (padded to 12 bits).

E (padded with zeros) is added to A. One's complement addition is used, that is, addition with end-around carry.

E (padded with zeros) is subtracted from A. That is, E is padded with zeros, complemented and then added to A with end around carry.
