A or one with hundreds and thousands.

It is possible to say a hundred (100) or one hundred (100); a/one hundred and one (101); a thousand (1,000) or one thousand (1,000); a/one thousand and one (1,001) (up to 1,099).

However, we must say, one thousand (1,000) in front of the hundreds, eg. one thousand, two hundred (1,200); one thousand, two hundred and sixty (1,260); etc.

Also, with numbers over 1,000, we say one in front of the hundreds: two thousand, one hundred and three (2,103); and not, two thousand, a hundred and three.

See other uses of a and an with numbers...

We normally say and each time we "cross" the tens column:

A thousand and one (1,001) ...

One thousand, one hundred and one (1,101) ...

One thousand, one hundred and twenty-one (1,121) ...

(In US English, and is usually omitted.)

Hundreds and thousands.

Compare the above with:

A / one kilometre.   ...
One kilometre, four hundred metres.   ...

A / one pound   ...
One pound, fifty-five   ...

An / one hour   ...
An hour and twenty minutes.   ...
One hour and twenty minutes.   ...

There is another way to say the numbers over a thousand; especially with round numbers:

Eleven hundred (1,100)   ...
Twelve hundred (1,200)   ...
Fifteen hundred (1,500)   ...

Millions, billions and trillions.

A / one million (1,000,000) ... = a thousand thousand ...

We do not say "millions" as part of a number (the "s" is always omitted):

Three million, four hundred thousand, five hundred and thirty six.
(3,400,536) ...

But when making an estimate, we can say:

There are millions of dollars in the bank. ...
Tens of millions of people go hungry in the world. ...

But, be careful, with specific numbers we say:

Two million dollars (not, of dollars) ...
Three million sheep (not, of sheep) ...

The rules for millions are the same as for the higher numbers:

A / one billion (1,000,000,000) ... = a thousand million ...

A few years ago, a British billion was 1,000,000,000,000 but recently the British have adopted the US system.

Five billion, four hundred and fifty six million, three hundred thousand, eight hundred and twenty one. ...
(5,456,300,821)

A / one trillion (1,000,000,000,000) ... = a million million ...

Dozens, scores, etc.

Ten, a dozen = 12, a score = 20, a hundred, a thousand, a million, a billion, a trillion.

We can use these words to talk about convenient blocks of numbers followed by the preposition of. Using these words allows us to make a better estimate than a lot, very many, etc.

Tens of people came to the party (about 50 to 90).
There were dozens of letters on the doormat (probably less that a hundred)
There were hundreds of ants in the kitchen (300? 900?)
We saw thousands of ducks on the lake (3,000? 9,000)
You can see millions of stars with a good telescope (3 million? 9 million?)

The word score can be used in singular or plural:

Scores of chickens
A score of cars

The decimal point.

Remember that commas amd points are used in the following way:

8,800,504 = eight million, eight hundred thousand, five hundred and four. ...

9.807 = nine point eight 0 (zero) seven. ...
