We know that 9 is in the Thousands Place. So the 9 will become 9000.
We also know that 5 is in the Hundreds Place. So the 5 will become 500.
Due to the fact there are 0's in the Tens and Ones Place we will do anything with it because it won't add up anything. What I mean by add up is that it will keep the number the same as it is. So since the answer is 9000+500, 0 wont do anything.
