Arabic numerals, also called
Hindu-Arabic or
Indo-Arabic numerals, are the ten
digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, based on the
Hindu–Arabic numeral system, the most common system for the symbolic representation of numbers in the world today. In this system, a sequence of digits such as "975" is read as a single
number, using the position of the digit in the sequence to interpret its value. The symbol for
zero is the key for the effectiveness of the system, which was developed by ancient
mathematicians in the Indian Subcontinent around AD 500.
