No problem, let's work through this together. We're starting with 3312 and 5257 and adding them all up.

Step 1: We'll start by adding the digits 2 & 7 in column 1 and get 9.

Step 2: We'll start by adding the digits 1 & 5 in column 2 and get 6.

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

Step 4: We'll start by adding the digits 3 & 5 in column 4 and get 8.

So, 3312 + 5257 = 8569.
