Thus, Islamic mathematicians may have learned the number zero from India but “failed to make use of it in algebra.” Hundreds of years later, Fibonacci did not consider zero a number like other numerals, either instead, he referred to it as a symbol in his book Liber Abaci (Levy 93). 956 CE) of Baghdad traveled to the China Sea on the east, as far south as Zanzibar, and to the Atlantic on the west he speaks of the nine figures with which the Hindus reckoned (Smith and Karpinski). Suleimān the Merchant, a well-known Arab trader of the ninth century, may have introduced the Hindu-Arabic symbols (including the numeral zero) to European markets, and “Abū ‘l-Ḥasan ‛Alī al-Mas‛ūdī (d. Such incremental advancement may not have been revolutionary, but it was necessary for the preparation of later mathematicians (like Fibonacci) to push forward the next major math breakthrough (Livio 91). 930 CE), produced important but “only incremental progress” in the development of algebra, particularly of the use of the Golden Ratio (Sesiano). Islamic mathematicians in Egypt, such as Abu Kamil (c. Thus, zero was used in India for addition, subtraction, and multiplication but not division the concept of dividing something by “nothing” was too difficult for even the brilliant Brahmagupta (Levy 93). Because the idea of nothing was important in early Indian religion and philosophy, it was much more natural for them to adopt a symbol for it than it was for the Latin (Roman) and Greek systems (Knott, “Brief”). The concept of “nothing” in math may have been represented first by a dot to indicate an empty placeholder, but zero was first used as a number in the seventh century (rather than as a mere concept) by the Indian mathematician and astronomer Brahmagupta, who also devised rules for its use as a number (Levy 93). One of the earliest proofs of math skills practice is a papyrus written by an Egyptian scribe named Ahmes (∼1650 BCE), who recorded a “series of 87 exercises and problems, presumably for students to try with the assistance and guidance of a teacher” (Levy 21). Mathematics has evolved greatly since then today, math equations are so inconspicuously calculated by computers that most people tend to think about mathematics “only in the day-to-day context in which they themselves are immersed” (Radford). Long before Pythagoras or Euclid, man recorded counting by “scratching tally marks on a stick or bone” (Devlin, Man 13). “Even today a large part of mathematical and geometrical elementary education is based on the Euclidean tradition” (“Euclid”). Elements is considered by many the most scientifically significant mathematical work until the 20th century (“Euclid”). 300 BCE) provided definitions, postulates and axioms of geometry which Fibonacci knew well. Greek mathematician Euclid also greatly influenced Fibonacci as highlighted previously, his thirteen books (chapters) on geometry in Elements (c. Pythagoras was primarily interested in number theories and their application to music rather than the use of numbers for everyday computation (O’Shea). 569 – 475 BCE), who coined the term ‘mathematics’ (Μάθημα, ατος, τo, that which is learned) to represent that abstract science which studies shape, quantity, and space (Donnegan 26). Leonardo Pisano, or ‘Fibonacci,’ was a self-professed student of the arts of Greek theologian and mathematician Pythagoras (c.
