  Kinda. The Arabians changed them a little bit. It’s more correct to say the system was developed by both people exchanging ideas, but the vast majority of it in India.

    That’s why I learned them as Hindu-Arabic numerals growing up

    yeah they changed the appearance of the number symbols a little bit, but i would say the real genius in the system is that it’s a place-value system and that each digit is valued 10 times more than the one after it. that’s the core of the system, the rest is just a make-up appearance.

      Yes, technically putting a “0” instead of letting the place empty is included in “changing the appearance a little bit”, but your comment pre-edit undersells the innovation.

        i thought the indians already put a dot in place to denote zero?

        From the wikipedia page: en.wikipedia.org/wiki/Numeral_system

        Indian mathematicians, such as Brahmagupta in the 7th century, played a crucial role in formalizing arithmetic rules and the concept of zero, which was later refined by scholars like Al-Khwarizmi in the Islamic world.
