No problem, let's work through this together. We're starting with 2489 and 3000 and adding them all up.

Step 1: We'll start by adding the digits 9 & 0 in column 1 and get 9.

Step 2: We'll start by adding the digits 8 & 0 in column 2 and get 8.

Step 3: We'll start by adding the digits 4 & 0 in column 3 and get 4.

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

So, 2489 + 3000 = 5489.
