I always thought there was at least SOMETHING that came from the arabs: Turkish towels. Then I learned that the Turks aren’t arabs. Of course, there is that arabic numerals idea. Oh well.
They actually came from India.
Yeah. And doing long division with the hexadecimal number system is not so easy, either.
Arabic numerals (and the concept of zero) were derived from a system invented by Hindus in India. Muslims did capture, translate, preserve, and carry back to Europe for retranslation from Arabic quite a lot of classical writings that were otherwise lost after the fall of the western Roman Empire. But besides some unique architectural styles and decorative arts they have invented almost nothing.
I found it! I found it!
What?! What?!
Nothing! Nothing!
