Sure thing! We've got 1003 and 4500 and we're gonna add them together.

Step 1: We'll start by adding the digits 3 & 0 in column 1 and get 3.

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

Step 3: We'll start by adding the digits 0 & 5 in column 3 and get 5.

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

So, 1003 + 4500 = 5503.
