• 3 – Three
• 4 – Four
• 5 – Five
• 6 – Six
• 7 – Seven

• The metro is leaving from line three.
• I have four brothers.
• We need five apples to make an apple pie.
• My cousin is seven months pregnant.
• The train leaves at nine o’clock.
• I live ten minutes away from here.

## Use

We use cardinal numbers to express a general number of people, animals or things (to talk about how many of those things there are).

## Summary

Cardinal numbers are used to express the quantity of things, people and animals. These numbers are usually placed before or after a noun.

Cardinal numbers are: zero, one, two, three, four, five, six, seven, eight, nine and ten.

For example:
