Adding Numbers: Add two and three-digit numbers

In this activity, we'll look at how to add two and three digits numbers together.

For example: 

Question - Can you add the numbers below together?

So, how do we do this?

1) First, we add the 100 columns first - 900 + 0 = 900

2) Then, we add the 10 columns - 60 + 30 = 90

3) Next, we add the ones - 9 + 8 = 17

4) Finally, we add these together - 900 + 90 + 17 = 1007

 

Remember to put 0s as placeholders
