No problem, let's work through this together. We're starting with 6111 and 2117 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 1 & 1 in column 2 and get 2.

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

Step 4: We'll start by adding the digits 6 & 2 in column 4 and get 8.

So, 6111 + 2117 = 8228.
