No problem, let's work through this together. We're starting with 17 and 3021 and adding them all up.

Step 1: We'll start by adding the digits 7 & 1 in column 1 and get 8.

Step 2: We'll start by adding the digits 1 & 2 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 0 & 3 in column 4 and get 3.

So, 17 + 3021 = 3038.
