Writing Numbers

Writing Numbers

Writing numbers as words means replacing the digits with words. Writing words as digits, or figures, means taking the words and turning them into a number.

1 to 9 Single-digit numbers are zero, one, two, three, four, five, six, seven, eight and nine.
10 to 19 The numbers from 10 to 19 are written as: ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen and nineteen.
20 to 99 The numbers from 20 to 99 are written using a multiple of ten, followed by the unit.  The multiples of 10 are: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety. 45 is forty five. If the number ends in zero, write the tens number only: 80 is eighty.
100 to 999 Write the number of hundreds, followed by the word hundred, then the rest of the number. 362 is three hundred and sixty two.  Zeroes are ignored: 405 is written as four hundred and five.
1000 to 9999 Four digit numbers are written by using thousand. 3476 is three thousand four hundred and seventy six. And 5008 is five thousand and eight.
10 000 and upwards The first part of a number with four, five or six digits is written in thousands. 56 785 is written as fifty six thousand, seven hundred and eight five. The number 406 090 is written as four hundred and six thousand and ninety.

Numbers with seven, eight or nine digits, are millions. 46 758 442 is forty six million, seven hundred and fifty eight thousand, four hundred and forty two.

Numbers may be shown as 45,895 (with a comma) or 45 895 (with a space) in groups of three digits).  The comma or space has no mathematical value.
