**A numeric number, more commonly referred to as a numeral, is a symbol or name used to represent a number.** A numeral may be expressed in words, such as seventy-five, or by arranging digits in a place-value system, such as by writing 75.

A digit is a single symbol used to denote a numeral. The most commonly used digits are the Hindu-Arabic numerals 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Digits are arranged in a specific order to tell a reader the precise value being expressed. For example, in the numeral 123.45, 1 is in the hundreds place, 2 is in the tens place, 3 is in the ones place, 4 is in the tenths place, and 5 in the hundredths place.
