А. Cardinal numbers. Количественные числительные

379 – three hundred and seventy nine, 5,084 – five thousand and eighty-four

2,000 000 – two million, 2,567 – two thousand five hundred and sixty seven,

450,000 – four hundred and fifty thousand, 5,000,000 – five billion

There is no plural after hundred, thousand, million and billion when they are part of a number. When we are talking more generally, they can be plural, e.g. thousands of people; millions of insects.

E.g.: There are thousands of books in the library (B библиотеке тысячи книг).

В. Ordinal numbers and dates. Порядковые числительные и даты

Порядковые числительные в английском языке образуются при помощи добавления определенного артикля -the – и окончания -th – к количественному числительному:

e.g.: six – the sixth, seven – the seventh

Но следует запомнить следующие порядковые числительные:

One – the first, two – the second, three – the third, five – the fifth

One problem with dates is that we write them and say them in a different way.

Запомните, как произносятся даты в английском языке!

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 2003 = two thousand and three

REMEMBER HOW TO PRONOUNCE THE DATES!

1993 – Nineteen ninety three

1903 – Nineteen oh three

2000 – The year of 2 thousand

2008 – The year of 2 thousand and eight

Fractions and decimals. Дроби

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

Percentages. Проценты

26 % is spoken as twenty-six per cent.

More than 50 % of something is the majority of it; less than 50 % is the minority.

Больше 50 % чего-либо – это большинство, менее 50 % чего-либо – это меньшинство.

Arithmetic. Арифметические действия

There are four basic processes. Notice how they are said when we are working out (= calculating) the answer.

+ = addition сложение	e.g.	6 + 4 = 10 (six plus/and four equals/is ten)
- = subtraction вычитание	e.g.	6-4 = 2 (six minus four equals/is two)
x = multiplication умножение	e.g.	6 x 4 = 24 (six times/multiplied by four equals/is twenty-four)
: = division деление	e.g.	8 : 2 = 4 (eight divided by two equals/is four)

Some people are not very good at mental arithmetic (= arithmetic in your mind without paper) and often get stuck (= have a problem) if they have to work something out. The easiest way is to use a calculator (= small electronic machine for working out numbers).

Некоторые люди не умеют считать в уме и часто испытывают в этом трудности. Самый легкий способ – воспользоваться калькулятором.

Saying '0'. Как произносить ‘0’

Telephone numbers: 567 23 03 – five six seven two three oh three.

Mathematics: 0.3 – nought point three;

5.03 – five oh three = five point nought three.

Temperature: -5 degrees = five degrees below zero = minus five degrees;

+5 degrees = five degrees above zero = plus five degree.
