Addition of multi-digit numbers with a carry
Test your understanding of addition with a carry by practicing it! Work through the below exercises to use it in practice.
🎙️
Let's add 25 and 48 together
🎙️
When we're adding numbers with more than one digit, it's best to set them up in columns. Make sure that the ones digits are on top of each other.
🎙️
Now we can start to add. We start with the ones. 5 plus 8, or 8 plus 5, is equal to 13. The order doesn't matter.
🎙️
With the 13, we have a ones digit of 3, let's put that at the bottom in the ones column. But we also have a tens digit of 1. Let's split that apart and put our tens digit in the tens column.
🎙️
Now for the tens column, we can add 1 plus 2 plus 4, and get 7. So, in our tens column, we'll have a 7
🎙️
So our final answer is 73. We can continue this pattern of adding and carrying for any size of number.
