No problem, let's work through this together. We're starting with 4044 and 5245 and adding them all up.

Step 1: We'll start by adding the digits 4 & 5 in column 1 and get 9.

Step 2: We'll start by adding the digits 4 & 4 in column 2 and get 8.

Step 3: We'll start by adding the digits 0 & 2 in column 3 and get 2.

Step 4: We'll start by adding the digits 4 & 5 in column 4 and get 9.

So, 4044 + 5245 = 9289.
