No problem, let's work through this together. We're starting with 2000 and 3302 and adding them all up.

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

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

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

Step 4: We'll start by adding the digits 2 & 3 in column 4 and get 5.

So, 2000 + 3302 = 5302.
