No problem, let's work through this together. We're starting with 2311 and 7247 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 & 4 in column 2 and get 5.

Step 3: We'll start by adding the digits 3 & 2 in column 3 and get 5.

Step 4: We'll start by adding the digits 2 & 7 in column 4 and get 9.

So, 2311 + 7247 = 9558.
