“Muslim scholars” contributed largely in the field of Mathematics in the golden age of Islamic civilization. “Arabic number system” is widely used even today.
The first great achievement was introduction of ‘’Arabic numerals’’. It explains the "place-value" theory, which allows numbers to be expressed by “nine figures” and zero.
