His story is quite logical from the Arab point of view. Some point to the brilliance of Arabs inventing algebra, but that was before 700 years of cousins marrying cousins. This guy’s explanation will seem perfectly logical to many today.
Think Nicole Simpson.
‘Arabs’ inventing algebra gives them too much credit. It was like the invention of the wheel- it was bound to happen.
Some would be silly then. The Arabs never understood anything other than pillaging and raping. During their raids they took the various royals smart persons as slaves. These early mathematicians, none of them arab, invented the zero and algebra just as the other oft attributed developments were invented by the captured thinkers of other cultures.
The Arabs did not invent algebra. The origins were in Babylon, the Greeks and Indians added to that, and Descartes gave us modern algebraic notation. Yes, some Arabs were involved, but it was very far from being all their creation. https://en.wikipedia.org/wiki/Algebra
They didn’t invent algebra, they stole it from the Greeks.
Algebra and “Arabic” numerals were in Sanskirt texts long before mohammed was born.
