Expressing Numbers in English
:: If a number is in the range 21 to 99, and the second digit is not zero, we should write the number as two words separated by a hyphen:
25   twenty-five
57   fifty-seven
89   eighty-nine

:: Numbers over 100 are generally written in figures. However if you want to say them aloud or want to write them in words rather than figures you put 'and' in front of the number expressed by the last two figures. For example:
203      two hundred and three            
622      six hundred and twenty-two

:: Numbers between 1000 and 1,000,000 is usually said or written in words as:
1,803    one thousand, eight hundred and three
1,963    one thousand, nine hundred and sixty-three
2,840    two thousand, eight hundred and forty

:: Saying years. We normally say a year in two parts. In the case of years ending in "00", we say the second part in "hundred":
1058   ten fifty-eight
1706   seventeen hundred and six (or 'seventeen oh six')
1865   eighteen sixty-five
1900   nineteen hundred

There are two ways of saying years ending in "01" to "09" before 2000. For example: "1901" can be said as "nineteen oh one" or "nineteen hundred and one". The year 2000 is read "two thousand", 2006 "two thousand and six". Post-2010 dates are often said as normal (2010 would be "twenty ten").

:: Expressing millions    
1,412,605     one million four hundred and twelve thousand six hundred and five  2,760,300     two million seven hundred and sixty thousand three hundred



 

There is / There are

An explanation video about There is and There are: 




THIS IS THE EXPLANATION: 
We use there is and there are to say that something exists.


Positive Sentences

We use there is for singular and there are for plural.
  • There is one table in the classroom.
  • There are three chairs in the classroom.
  • There is a spider in the bath.
  • There are many people at the bus stop.


Contractions

The contraction of there is is there's.
  • There's a good song on the radio.
  • There's only one chocolate left in the box.
You cannot contract there are.
  • There are nine cats on the roof.
  • There are only five weeks until Christmas.


Negative Form

The negative is formed by putting not after is or are:
  • There is not a horse in the field.
  • There are not eight children in the school.
  • There is not a tree in the garden.
  • There are not two elephants in the zoo.
The Negative contractions are:
There's not = There isn't
There are not = There aren't


There Are with ANY

When we want to indicate that a zero quantity of something exists we use there aren't any.
  • There aren't any people at the party.
  • There aren't any trees in my street.
We also use this structure with uncountable nouns:
  • There isn't any water in the swimming pool.
  • There isn't any sugar in my coffee.


Questions

To form a question we place is / are in front of there.
Again we use any with plural questions or those which use uncountable nouns.
We also use there is / are in short answers.
  • Is there a dog in the supermarket? - No, there isn't.
  • Are there any dogs in the park? - Yes, there are.
  • Is there a security guard in the shop? - Yes, there is.
  • Are there any polar bears in Antarctica? - No, there aren't.
  • Is there any ice-cream in the freezer? - Yes, there is.


How Many with Are There

If we want to find out the number of objects that exist we use How many in the following form:
How many + plural noun + are there (+ complement).
  • How many dogs are there in the park?
  • How many students are there in your class?
  • How many countries are there in South America?
  • How many Star Wars films are there
