No problem, let's work through this together. We're starting with 2002 and 2844 and adding them all up.

Step 1: We'll start by adding the digits 2 & 4 in column 1 and get 6.

Step 2: We'll start by adding the digits 0 & 4 in column 2 and get 4.

Step 3: We'll start by adding the digits 0 & 8 in column 3 and get 8.

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

So, 2002 + 2844 = 4846.
