to its owner, and a share to the other, a share remains for the sons that equals its third, so the entire estate is seven. By algebra, you take an estate and remove a share from it, a remainder of an estate minus a share remains, and you pay half of the remainder to the other legatee, half an estate minus half a share remains, which equals three shares; so compensate it by half a share, and add it to the three, a complete half remains, which equals three and a half, so the entire estate is seven.

Section: If the second bequest is of half of what remains of the third, you take the divisor of the half and the third, which is six, subtract one from it, and five remain, which is the share. Then you add one to the shares of the sons and multiply them by the divisor, which becomes twenty-four, subtract three from it, twenty-one remain, which is the estate. You pay five to the owner of the share, two remain from the third, you pay one share from them to the other legatee, fifteen remain, five for each son. By the second method, you add a half to the shares of the sons and multiply them by the divisor, becoming twenty-one. By the third, you act as you did in the first, so when it reaches seven, you multiply it by three because the second bequest is of half of the third. By the fourth, you make the third two shares and a share, pay the share to its owner and a share to the other; five shares and two shares remain from the estate, pay two shares to two sons, five remain for the third, which is the share, so when you expand it, it is twenty-one. By algebra, you take an estate and cast from it its third as a share, and pay to the other half of the remainder of the third, there remains from the estate five-sixths minus half a share, compensate it with half a share, and add it to the shares of the sons, it becomes three and a half, equal to five-sixths, invert and convert, the share becomes five, and every share six, totaling twenty-one.

Section: If he bequeaths to a third a fourth of the estate, take the divisors, which are two, three, and four, and multiply some of them by others, becoming twenty-four, and add one to the number of the sons, becoming four, and multiply it by twenty-four, becoming ninety-six, subtract from it the multiplication of half a share by twenty-four, which is twelve, eighty-four remains, which is the estate. Then look at the twenty-four, subtract its sixth from it for the second bequest, and its fourth for the sake of the
