How did the arab empire affect learning, culture, and the arts in europe

Alot of people in Europe were not educated because you had to have money to go to school and learn for example math the hard types so, the Europeans heard that there was people that were down south in the Arab region learning together the Europeans didn't even know where the number 0 came from they found out that it was first brought by the very intelligent scholars that were influenced by Isalm and the roots of the arab culure. 
hopefully that helps
