Jabarkan Al-Qalasadi dari Matematik pada zaman pertengahan Islam dalam bahasa melayu

Moorish mathematician Abu'l Hasan ibn Ali al Qalasadi (b. 1412) used symbols in algebra, though symbols were used by other Islamic mathematicians much earlier.

In the time of the Ottoman Empire (from 15th century onwards) the development of Islamic mathematics became stagnant. This parallels the stagnation of mathematics when the Romans conquerored the Hellenistic world.
