Numerals are called Hindu Arabic, because they were invented by the Ancient Hindus during the 9th century, and then later adopted by the Arabic Persians in a book titled On the Use of Indian Numerals, which was brought to Western culture during the Middle Ages.
The concept of zero
Arabic numerals were invented in India (and later brought to Europe by Arabs).
But no facts have been given to decided which is true about Arabic numerals and so therefore an answer is not possible although it is true that Arabic numerals contain a zero symbol which makes arithmetic a lot easier.
Arabic numerals are called that because the European interpretation of those numbers comes from the Arabs. The numerals are called Arabic numerals (even though they do not resemble modern Arabic numerals in the slightest) to distinguish them from Roman numerals.
