Worksheet Overview

QUESTION 1 of 10

Subtraction is taking something away.

It is the opposite of addition. (Addition is adding something on.)

 

Look at this example.

take 4 away from 20 equals  16

 

We can write it like this, too.

20 - 4 = 16

 

We take 4 away from 20 to get 16. That's subtraction!

Now try for yourself.
