Let's solve this addition problem. We have 2223 and 2438, and we need to add them together.

Step 1: We'll start by adding the digits 3 & 8 in column 1 and get 11.
We'll write down the last digit 1 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 2 & 3 in column 2 and get 6.

Step 3: We'll start by adding the digits 2 & 4 in column 3 and get 6.

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

So, 2223 + 2438 = 4661.
