Arabic AR uh bihk, numerals, also called Hindu-Arabic numerals, are the most common symbols used to represent numbers. Every number can be expressed in Arabic numerals by using 10 basic symbols, alone or in combination. The basic symbols, called digits, are 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The position of a digit in an Arabic numeral determines its value. For example, the Arabic numeral for the number two hundred thirty-seven is the sequence of digits 237. In this numeral, the digit 2 has a value of two hundred, the digit 3 has a value of thirty, and the digit 7 has a value of seven. The Arabic numeral for the number seven thousand three is 7,003. In this case, the digit 7 has a value of seven thousand, and the digit 3 has a value of three. The digit 0 (zero) fills empty positions so that the other digits have their proper values.
