Let's solve this addition problem. We have 203 and 4082, and we need to add them together.

Step 1: We'll start by adding the digits 3 & 2 in column 1 and get 5.

Step 2: We'll start by adding the digits 0 & 8 in column 2 and get 8.

Step 3: We'll start by adding the digits 2 & 0 in column 3 and get 2.

Step 4: We'll start by adding the digits 0 & 4 in column 4 and get 4.

So, 203 + 4082 = 4285.
