** 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**3,000,000,000**= three**billion**

*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**= one and_{ }1/4**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** - tennis:
**40-0**= forty**love**
