Cardinal Numbers

Hey there, amigringo, how are you today?

Do you know the cardinal numbers in English? The cardinal numbers are the ones we use to count things, and they are infinite.

0 → zero

1 → one

2 → two

3 → three

4 → four

5 → five

6 → six

7 → seven

8 → eight

9 → nine

10 → ten

See some examples:

We need five (5) apples.

I have two (2) cats.

She's seven (7) years old now.

They meet four (4) times a week.

Are you free at eight (8)?

As we keep going, you will notice that eventually we start repeating numbers. They follow patterns as they grow bigger. This makes everything easier.

11 → eleven

12 → twelve

13 → thirteen

14 → fourteen

15 → fifteen

16 → sixteen

17 → seventeen

18 → eighteen

19 → nineteen

20 → twenty

21 → twenty-one

22 → twenty-two

23 → twenty-three

24 → twenty-four

25 → twenty-five

26 → twenty-six

27 → twenty-seven

28 → twenty-eight

29 → twenty-nine

30 → thirty

See some examples:

We have fifteen (15) books to donate.

I bought five (5) bars of chocolate.

They rescued twenty-four (24) cats.

We met at in school at thirteen (13).

I need thirty (30) volunteers for this event.

From here on, all the number will follow the same pattern and keep repeating the units. Notice that we will keep separating the tens from the units.

40 → forty

50 →fifty

60 → sixty

70 → seventy

80 → eighty

90 → ninety

100 → one/a hundred

101 → one/a hundred one

102 → one/a hundred two

103 → one/a hundred three

etc...

See some examples:

My apartment number is one hundred one (101).

His mother is sixty-seven (67) now.

I have fifty-three (53) guests.

She read forty (40) books this year.

Forty-four (44) hours of work is too much.

Her grandmother is eighty-four (84) years old.

The bigger number will also keep repeating, so once you know the first ones, you can just keep going.

200 → two hundred

300 → three hundred

400 → four hundred

500 → five hundred

600 → six hundred

700 → seven hundred

800 → eight hundred

900 → nine hundred

1,000 → one/a hundred

1,000,000 → one/a million

See some examples:

I watched this movie two hundred (200) times.

The Russian Revolution was a hundred eight (108) years ago.

The continent was invaded five hundred thirty-three years (533) ago.

We need seven thousand (7,000) signatures.

He must study for one thousand (1,000) hours.
