Not to worry, we've got 1250 and 4499. Let's get to adding them!

Step 1: We'll start by adding the digits 0 & 9 in column 1 and get 9.

Step 2: We'll start by adding the digits 5 & 9 in column 2 and get 14.
We'll write down the last digit 4 and carry the 1 to the next column.

Step 3: We'll start by adding the digits 2 & 4 in column 3 and get 7.

Step 4: We'll start by adding the digits 1 & 4 in column 4 and get 5.

So, 1250 + 4499 = 5749.
