No problem, let's work through this together. We're starting with 4361 and 1125 and adding them all up.

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

Step 2: We'll start by adding the digits 6 & 2 in column 2 and get 8.

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

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

So, 4361 + 1125 = 5486.
