Andalusian schools had a great impact on the transfer of Islamic civilization to Europe in various fields of science, the most prominent of which was the mathematical sciences that flourished in Andalusia and from there moved to Europe and reached it the writings of Muslim mathematicians such as Thabit bin Qurra, Ibn Sinan and others, and one of the most important manifestations of this civilizational communication in the field of Mathematics: I introduced the decimal numbering to Europe, and the zero was the most prominent arithmetic symbol that Muslims were guided to. Andalusian schools helped spread the Arabic and Islamic sciences, which were translated in Andalusia as the book of the mathematical scientist Al-Khwarizmi, which was translated into Latin Spanish in the twelfth century AD.The translated book was transferred to Germany and called it (Alogorizmus). Thanks to these and others, algebra and geometry advanced and Europe helped advance in analytic geometry by calculus. As for the field of optics, we find that the Andalusian Mars contributed to the translation of Ibn Al-Haythams writings, such as his treatise The Mirrors Marked with Circles into Latin in Toledo in the twelfth century AD. The Latin translations taken by European students show that the original Arabic texts were transferred to these languages through schools in Andalusia. The bimaristans in Andalusia were like medical schools for students from all sides, especially the delegations of large numbers of European students to learn medical sciences at the hands of Andalusian physician scientists, before the Europeans established medical schools, which were joined by hospitals after that. Andalusian doctors had a prominent impact on the development of this science in Europe. As for the Andalusian libraries, we find that the rulers of Andalusia were interested in building them and bringing books of eastern scholars, such as the Prince Abdul Rahman II, who was interested in astronomy and is the first to introduce astronomical tables to Andalusia.
