Hello everyone Welcome to a new video from X3English
We can find numbers everywhere in our life
as they are connected to everything we do
In today's lesson
We are going to dive into the world of Cardinal numbers and Ordinal numbers in English
Cardinal numbers
Cardinal numbers are numbers referring to quantity
they can be used to tell the number of things in a group
Let's start by looking at numbers 1 to 12
0 - Zero
1 - One
2 - Two
3 - Three
4 - Four
5 - Five
6 - Six
7 - Seven
8 - Eight
9 - Nine
10 - Ten
11 - Eleven
12 - Twelve
All the numbers 13 to 19 have something in common
They have -teen at the end of the letters. These numbers are
Thirteen
Fourteen
Fiffteen
Sixteen
Seventeen
Eighteen
Ninteen
Next we will be looking at numbers from 20 to 99
You will probably notice that the numbers 1 to 9
Are repeated after every ten numbers with the relevant prefix
This can be seen as follows
Twenty
Twenty-one
Twenty-two
Twenty-three
Thirty
Thirty-four
Forty-five
Fiffty
Sixty-six
When the numbers get to three digits
They are called hundreds
For example
One hundred
Six hundred and twenty-two
When the numbers are between 4 & 6 digits, they are in thousands
You will notice that the tens hundreds and thousands
are all mentioned when spelling the numbers
For example
Three thousand two hundred and ninety
One hundred and twenty two thousand one hundred and ten
When the numbers have tens, hundreds and thousands
and more digits are added to reach seven figures
The numbers are in millions
For example
One million
Two million five hundred thousand six hundred and ten
Ordinal numbers
Ordinal numbers are numbers defining the position of something in a list
They are normally made by adding -th at the end of all numbers
With the exception of one two and three
you'll also notice that some spellings change slightly
Five becomes Fifth
Nine becomes Ninth
Thirteen becomes Thirteenth
Two-Hundred becomes Two-hundredth
One becomes First
Two becomes Second
Three becomes Third
They could be used in sentences as follows
1. I came second in the swimming competition
2. He went to the fourth floor
And that's all for today's lesson on numbers in English
