No problem, let's work through this together. We're starting with 232 and 3131 and adding them all up.

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

Step 2: We'll start by adding the digits 3 & 3 in column 2 and get 6.

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

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

So, 232 + 3131 = 3363.
