No problem, let's work through this together. We're starting with 3029 and 5003 and adding them all up.

Step 1: We'll start by adding the digits 9 & 3 in column 1 and get 12.
We'll write down the last digit 2 and carry the 1 to the next column.

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

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 3 & 5 in column 4 and get 8.

So, 3029 + 5003 = 8032.
