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.
Plus... Was Algebra the LAST thing they claim to have invented?
That was only hundreds of years ago... What have you done lately?
Or was that the pinnacle of their claims to successes?
