What is Subtraction?

Subtraction is taking away one number from another.
It helps us find out how many are left after something is taken away.
It is the opposite of addition.

Examples:

Eating cookies:
- If you have 10 cookies and eat 3, you subtract 3 from 10.
- You have 10 - 3 = 7 cookies left!

Books on a shelf:
- If there are 5 books on a shelf and you give 2 to a friend, you take away 2.
- You have 5 - 2 = 3 books left on the shelf!

Marbles in a jar:
- If you have 12 marbles in a jar and lose 4 while playing, you subtract 4.
- You have 12 - 4 = 8 marbles left!
