Let's solve this addition problem. We have 2219 and 7204, and we need to add them together.

Step 1: We'll start by adding the digits 9 & 4 in column 1 and get 13.
We'll write down the last digit 3 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 1 & 0 in column 2 and get 2.

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

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2219 + 7204 = 9423.
