them who belong to one class, such as daughters, allocate the surplus among them equally⦗1⦘. If they belong to different classes, take the number of their shares from the constant base of six⦗2⦘.

Thus, a grandmother and a uterine brother are reckoned on a denominator of two; a mother and a uterine brother on three; a mother and one daughter on four; and a mother with two daughters on five—and it never exceeds five, for if another sixth were added the statutory shares would consume the entire estate.

When one of the spouses is present, first work out the radd calculation, then the spousal calculation. Whatever remains after the spouse’s fixed share is apportioned to the radd calculation⦗3⦘; if it divides evenly⦗4⦘, the radd calculation stands vis-à-vis the spousal calculation, otherwise multiply the radd denominator by the spousal denominator.

Next, anyone entitled through the spousal calculation takes his portion multiplied by the radd denominator⦗5⦘, and anyone entitled through the radd calculation takes his portion multiplied by the surplus that remains after assigning the spousal share⦗6⦘. For example, with a husband, a grandmother, and a uterine brother, multiply the radd denominator—two—by the spousal denominator—also two; the problem is thereby resolved on a denominator of four, and so on.
