An example is the equation x + 4 = 6. The latter enabled Middle Eastern scholars to calculate values for angles and sides of triangles and to advance studies in astronomy. It is usually rather difficult to tell whether a given Diophantine equation is solvable. This book included many word problems, especially dealing with inheritance. were Greek. Although The Porisms is lost, we know three lemmas contained there, since Diophantus refers to them in the Arithmetica. To give one specific example, he calls the equation 4 = 4x + 20 'absurd' because it would lead to a negative value for x. He also considered simultaneous quadratic equations. Muḥammad ibn Mūsā al-Khwārizmī (Persian: Muḥammad Khwārizmī محمد بن موسی خوارزمی ; c. 780 – c. 850), Arabized as al-Khwarizmi and formerly Latinized as Algorithmi, was a Persian polymath who produced vastly influential works in mathematics, astronomy, and geography. Diophantus wrote several other books besides Arithmetica, but very few of them have survived. The portion of the Greek Arithmetica that survived, however, was, like all ancient Greek texts transmitted to the early modern world, copied by, and thus known to, medieval Byzantine scholars. The father of algebra: Abu Jaafar Mohammad Ibn Mousa Al Khwarizmi. ], Manipulating algebra fractions by Mickb [Solved! The term al-jabr in its Arabic title, Kitab al-jabr wa’l-muqabala, is the source of the English word algebra. Latinized versions of his name and of his most famous book title live on in the terms algorithm and algebra. ^ par. given any a and b, with a > b, there exist c and d, all positive and rational, such that, Diophantus is also known to have written on polygonal numbers, a topic of great interest to Pythagoras and Pythagoreans. Al-Khwarizmi’s book Calculation With Indian Numerals promoted the decimal system. One lemma states that the difference of the cubes of two rational numbers is equal to the sum of the cubes of two other rational numbers, i.e. But research in papyri dating from the early centuries of the common era demonstrates that a significant amount of intermarriage took place between the Greek and Egyptian communities [...] And it is known that Greek marriage contracts increasingly came to resemble Egyptian ones. Al-Khwarizmi: The Father of Algebra We explore the origins of algebra and mathematics that underpin the science of flight and the transport of the future. Christianidis, J. One solution was all he looked for in a quadratic equation. ", Margin-writing by Fermat and Chortasmenos. This Islamic mathematician was also instrumental in encouraging the use of the number 0 as a place holder. Likely born in what is now Uzbekistan in about 780 C.E., al-Khwarizmi is called the “great hero of Arabic mathematics.” Why did he receive this acclaim? What is your favorite math activity? “Our author (Diophantos) not the slightest trace of a general, comprehensive method is discernible; each problem calls for some special method which refuses to work even for the most closely related problems. For this reason it is difficult for the modern scholar to solve the 101st problem even after having studied 100 of Diophantos’s solutions”.[9]. Diophantus is often called “the father of algebra" because he contributed greatly to number theory, mathematical notation, and because Arithmetica contains the earliest known use of syncopated notation.[13]. He also lacked a symbol for a general number n. Where we would write 12 + 6n/n2 − 3, Diophantus has to resort to constructions like: "... a sixfold number increased by twelve, which is divided by the difference by which the square of the number exceeds three". Al-Khwarizmi helped establish widespread use of Hindu-Arabic numbers: which replaced Roman numerals (common throughout Europe and the Middle East as a result of the spread of the Roman Empire), until then: The Hindu-Arabic system was much easier to use when performing mathematical operations, since it is a base-10 system. Abu Ja'far Muhammad ibn Musa al-Khwarizmi lived in Baghdad, around 780 to 850 CE (or AD). They later took the knowledge home, aided by educated Muslim captives and immigrants. Editions of Arithmetica exerted a profound influence on the development of algebra in Europe in the late sixteenth and through the 17th and 18th centuries.

Diophantus was the first Greek mathematician who recognized fractions as numbers; thus he allowed positive rational numbers for the coefficients and solutions.

Around 825 he wrote the book "Hisab Al-jabr w’al-muqabala", from which we get the word algebra (meaning 'restoration of broken parts').
