Addition is adding something on.
When you add everything together, you get a total.
Example
Look at this addition:
16 + 2 = ?
Answer
Start at 16 and count 2 forward.
What do you get then?
Use the number line below to help you count on.
16 + 2 = 18
Start at the number 16 on the number line. Move 2 numbers to the right and you get to 18. So, 16 + 2 = 18.
Always move to the right on a number line when you are adding.
Now it's time to have a go at the questions.
Tip: You always have to add 2 to find your total.
