Jelaskan Al-Samawal dari Matematik pada zaman pertengahan Islam dalam bahasa melayu

Moroccan mathematician Al-Samawal (b. 1130) was an important member of al-Karaji's school of algebra. Al-Samawal was the first to give the new topic of algebra a precise description when he wrote that it was concerned "with operating on unknowns using all the arithmetical tools, in the same way as the arithmetician operates on the known."
