## Cardinal numbers

• 379 = three hundred and seventy nine
• 2,860 = two thousand eight hundred and sixty
• 5,084 = five thousand and eighty-four
• 470,000 = four hundred and seventy thousand
• 2,550,000 = two million, five hundred and fifty thousand

Note: There is no plural’s’ after hundred, thousand, million and billion when they are part of a number.

On their own, they can be plural, e.g. thousands of people; millions of insects.

## Ordinal numbers and dates

One of the problems with dates is that we write them and say them in a different way:

• We write 4 January (or 4th January), but say the fourth of January or January the fourth.
• We write 21 May (or 21st May), but say the twenty-first of May or May the twenty-first.
• 1997 = nineteen ninety seven
• 1905 = nineteen hundred and five or nineteen oh five

## Fractions and decimals

• 1 1/4 = one and a quarter
• 1 1/2 = one and a half
• 1 3/4 = one and three quarters
• 1 1/3 = one and a third
• 1.25 = one point two five
• 1.5 = one point five
• 1.75 = one point seven five
• 1.33 = one point three three

## Percentages

• 26% = twenty-six per cent
• More than 50% is the majority; less than 50% is the minority.

Arithmetic

There are four basic processes for working out (= calculating) a problem:

+ = addition e.g. 6 + 4 = 10 (six plus/and four equals/is ten)

= subtraction e.g. 6-4 = 2 (six minus four equals/is two)

X = multiplication e.g. 6 X 4= 24 (six times / multiplied by four equals/is twenty-four)

/ = division e.g. 4/2 = 2 (four divided by two equals/is two)

## Saying ‘0’

This can be spoken in different ways in different contexts.

• telephone number: 603 724 = six oh three, seven two four (AmEng = six zero three)
• mathematics: 0.7 = nought point seven, 6.02 = six point oh two
• temperature: -10 degrees = ten degrees below zero / minus ten degrees
• football: 2-0 = two nil
