Where did the scholars who worked in the house of wisdom come from?

The House of Wisdom was made possible by the consistent flow of Arab, Persian, and other scholars of the Islamicate world to Baghdad, owing to the city's position as capital of the Abbasid Caliphate.

Explanation:At the House of Wisdom, in Baghdad, scholars pored over Indian books on mathematics. These works used a set of ten symbols to represent numbers-not letters of the alphabet, as in Baghdad and Rome. In the early 800s, mathematician Muhammad ibn Musa al-Khwarizmi wrote a book on how to do math using the Indian system.
