Let's get this math done. We have 5082 and 4003 and we're going to add them all together.

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

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

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

Step 4: We'll start by adding the digits 5 & 4 in column 4 and get 9.

So, 5082 + 4003 = 9085.
