‘Arabs’ inventing algebra gives them too much credit. It was like the invention of the wheel- it was bound to happen.
**Arabs inventing algebra**
I’ve read that algebra, like so many other things, was stolen from India during the moslem invasions there.
Per my comment above:
Algebra and “Arabic” numerals were in Sanskrit texts long before Islam, along with many other mathematical methods as well as other advancements. Islam invented nothing of any use to humanity, it stole and claimed as its own.
