QUESTION 1 of 10

Subtraction is taking something away.

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.

Subtract 4 from 10. What are you left with?

Take away 8 from 10. What do you get?

What do you get if you take 5 away from 20?

Subtract 16 from 19. What are you left with?

Take away 13 from 16. What do you get?

What does 11 take away 4 equal?

17 take away 4 equals?
