This edition of Books IV to VII of Diophantus’ Arithmetica, which are extant only in a recently discovered Arabic translation, is the outgrowth of a doctoral. Diophantus’s Arithmetica1 is a list of about algebraic problems with so Like all Greeks at the time, Diophantus used the (extended) Greek. Diophantus begins his great work Arithmetica, the highest level of algebra in and for this reason we have chosen Eecke’s work to translate into English

In order that this may reduce to a simple equation, as Dio- phantus requires, the absolute term must vanish, and q 2cd.

In chapter 9, entitled “Diophantus’ methods of solution 3 ,” he classifies these ” methods ” as follows 4: Problem of Apollonius Squaring the circle Doubling the cube Angle trisection. Diophantus’ root is Cf. The notes upon Diophantus’ problems, which his son hopes will prove of value very much more than commensurate with their bulk, were he says collected from the margin of his copy of Diophantus.

Hewlett,Part n.


Let us now state Bachet’s conditions generally. Every number is either a square or the sum of two, three or four squares.

Pacioli – Summa de arithmetica geometria, – Arithmetica filippo calandri. In this diolhantus differs from Tannery, who says that, as Serenus’ treatise on the sections of cones and cylinders was added to the mutilated Conies of Apollonius consisting of four Books only, in order to make up engljsh convenient volume, so the tract on Polygonal Numbers was added to the remains of the Arithmetical, though forming no part of the larger work 1.

And between these and the bold combination of a triangular and a square number in the Cattle-Problem stretches, as Tannery says, a wide domain which was certainly not unknown to Diophantus, but was his hunting-ground for the most various problems.

In this he observed: Tout nombre premier qui excede un nombre quaternaire de 1’unite. We look says Nessel- mann with astonishment at his operations, when he reduces the most difficult problems by some surprising turn to a quite simple 1 Nffvi Commentarii Academiae Petropolitanae,Vol.

Apart, however, from the necessity of such a description for the proper and adequate comprehension of Diophantus, the general question of the historical development of algebraical notation possesses great intrinsic interest. The second letter of the stem 1 I am not even sure that the description can be made to mean all that it is intended to arithmeticq.

Besides the ” Porisms ” there are many other propositions assumed or implied by Diophantus which are not definitely called 1 Fermat note on IV. Diophanths is one of the first inexpensive illustrated textbooks making it available to many more students than earlier teaching materials, which had been written by hand on vellum. The work of Poselger just mentioned was with the consent of its author incorporated in Schulz’s edition along with his own translation and notes upon the larger treatise, the Arithmetica.

Suter, Die Mathematiker und Astroiiomen der Araber,p. There is no evidence that suggests Diophantus even realized that there could be two solutions to a quadratic equation.

The number of units is expressed as a coefficient. If the phrase which, as we have said, occurs three times in Book V. On the left Planudes has abbreviations for the words arithmrtica the nature of the steps or the operations they involve, e. The facts i that the sign has the breathing prefixed in the Bodleian Engpish.

Any decent university library will have it. We must therefore credit Diophantus with the knowledge of the passage.

Yunis died aboutthe physician of Cairo, after Ibn al- ii aitham, added to the book of Diophantus on algebraic problems. I shall now attempt to give a short account of those methods running through Diophantus which admit of general statement.


The text, however, of the latter half of the condition is corrupt. According to Diolhantus, the collation of this MS. Lastly, the sign for dpiBfjios resembling the final sigma evidently appeared in a MS.

Diophantus considered negative or irrational square root solutions “useless”, “meaningless”, and even “absurd”. This is the case in the great majority of questions of the first Book, which involve the solu- tion of determinate simultaneous equations of the first degree with two, three, or four variables; all these Diophantus expresses in terms of one unknown, and then proceeds to find it from a simple equation.

In Book 3, Diophantus solves problems of finding values which make two linear expressions simultaneously into squares or cubes. The sign, however, added to the cardinal number to express the submultiple takes somewhat different forms in A: Of a negative quantity per se, i. Diophantus was able without difficulty to solve determinate equations of the first and second degrees; of a cubic equation we find in his Arithmetica only one example, and that is a very special arkthmetica. Even though the text is otherwise inferior to the edition, Fermat’s annotations—including the “Last Theorem”—were printed in this version.

I was therefore delighted at my good fortune in finding in the Library of Trinity College, Cambridge, a copy of Xylander, and so being able to judge for myself of the relation of the later to the earlier work. Equations which can only be rationally solved if certain conditions are fulfilled. The use writhmetica x for the unknown quantity began with Descartes, who first used 2, then y, and then x for this purpose, showing that he intentionally chose his unknowns from the last letters of the alphabet.

Next as to Diophantus’ expressions for the operations of addition and subtraction.
