No problem, let's work through this together. We're starting with 3356 and 2022 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 5 & 2 in column 2 and get 7.

Step 3: We'll start by adding the digits 3 & 0 in column 3 and get 3.

Step 4: We'll start by adding the digits 3 & 2 in column 4 and get 5.

So, 3356 + 2022 = 5378.
