Gw mau tau Abu Bakr al-Karaji dari Matematik pada zaman pertengahan Islam. Jelasin dalam bahasa melayu

Algebra was further developed by Persian mathematician Abu Bakr al-Karaji (953-1029) in his treatise al-Fakhri, where he extends the methodology to incorporate integral powers and integral roots of unknown quantities.

Al-Karaji is seen by many as the first person to completely free algebra from geometrical operations and to replace them with the arithmetical type of operations which are at the core of algebra today. He was first to define the monomials  and  and to give rules for products of any two of these. He started a school of algebra which flourished for several hundreds of years.

The discovery of the binomial theorem for integer exponents by al-Karaji was a major factor in the development of numerical analysis based on the decimal system.
