No problem, let's work through this together. We're starting with 5116 and 2162 and adding them all up.

Step 1: We'll start by adding the digits 6 & 2 in column 1 and get 8.

Step 2: We'll start by adding the digits 1 & 6 in column 2 and get 7.

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 5 & 2 in column 4 and get 7.

So, 5116 + 2162 = 7278.
