No problem, let's work through this together. We're starting with 2313 and 2226 and adding them all up.

Step 1: We'll start by adding the digits 3 & 6 in column 1 and get 9.

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

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 & 2 in column 4 and get 4.

So, 2313 + 2226 = 4539.
