No problem, let's work through this together. We're starting with 1049 and 2450 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 4 & 5 in column 2 and get 9.

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

Step 4: We'll start by adding the digits 1 & 2 in column 4 and get 3.

So, 1049 + 2450 = 3499.
