The numbers used in the current arabic language were invented by indians, yes. They're now known as eastern arabic numerals.
Arabic numerals, however, the original ones, were 0 1 2 3 4 5 6 7 8 9. They were originally used in North Africa by arabs, and then the west caught on and started using them too. Check out wiki about them:
