  The auxiliary rules of quantum mechanics can be written without the Born rule
by using what are called the nRules. The nRules are understood in part by
making certain modifications in the Hamiltonian. In this paper, those
modifications are written directly into the nRules, reducing their number from
four to three. It is shown that the nRules in either form provide for a
definite direction in time, guaranteeing that a statistically irreversible
interaction is absolutely irreversible.
