Ahmad ibn Ibrahim ibn Ali ibn Munim al-Abdari (ar|أحمد بن ابراهيم بن علي بن منعم الأبداري; died 1228), often referred to as ibn Munim, was a mathematician, originally from Dénia in Andalusia. He lived and taught in Marrakesh where he was known as one of the best scholars in geometry and number theory.[1] [2] He is often confused with Muhammad ibn 'Abd al Mun'im, a different mathematician who worked in the court of Roger II of Sicily.[2]
