No problem, let's work through this together. We're starting with 1131 and 4817 and adding them all up.

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

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

Step 3: We'll start by adding the digits 1 & 8 in column 3 and get 9.

Step 4: We'll start by adding the digits 1 & 4 in column 4 and get 5.

So, 1131 + 4817 = 5948.
