![]() (To be manipulated by machine, these separators are usually omitted. When writing in numerals, to aid comprehension these groups of three digits are typically separated-for example, with a comma in countries where the decimal mark is the period.

For larger numbers, each additional numeral at the beginning of the string generally represents another power of ten.For example, "642" is "six hundred and forty two" and "919" is "nine hundred and nineteen". To name numbers 101 through 999 that are not multiples of 100, the name of a digit 1-9 is followed by "hundred" (the individual values are multiplied together) to express the first digit, and the rules for smaller numbers are used for the remainder (the values of the hundreds part and the remainder are summed)."Zero" never combines with other numbers in the naming system it is only pronounced in the name for 0. For example, "42" is "forty-two", which places a numeral " 4" before a numeral " 2" to indicate that the 4 represents "forty", or 4 times 10. To name numbers 21 through 99 that are not multiples of 10, a multiple of ten is followed by a single digit number 1-9, and the value is the sum.The names of the cardinal and ordinal numbers can be constructed from the below tables and a set of combining rules.Įach of the numbers specifically listed has a literal name that can be used on its own. 5 General rules for very large numbers (short and long scale)Įnglish generally uses a decimal counting system for natural numbers.
