**Symbolic algebra**In

Islamic mathematics , al-Qalasadi made the first attempt at creating an algebraic notation sinceIbn al-Banna two centuries earlier, who was himself the first to make such an attempt sinceDiophantus andBrahmagupta in ancient times. The notations of his predecessors, however, lacked symbols for mathematical operations. [*Harv|Boyer|1991|loc="Revival and Decline of Greek Mathematics" p. 178 "The chief difference between Diophantine syncopation and the modern algebraic notation is the lack of special symbols for operations and relations, as well as of the exponential notation."*] Al-Qalasadi'salgebra ic notation was the first to have symbols for these functions and was thus "the first steps toward the introduction of algebraic symbolism." He represented mathematical symbols using characters from theArabic alphabet , where:*"wa" means "and" for

addition (+)

*"illa" means "less" forsubtraction (-)

*"fi" means "times" formultiplication (*)

*"ala" means "over" for division (/)

*"j" represents "jadah" meaning "root"

*"sh" represents "shay" meaning "thing" for avariable (x)

*"m" represents "mal" for a square (x^{2})

*"k" represents "kab" for a cube (x^{3})

*"l" represents "yadilu" for equality (=)**See also***
