Sure thing! We've got 2507 and 2002 and we're gonna add them together.

Step 1: We'll start by adding the digits 7 & 2 in column 1 and get 9.

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 5 & 0 in column 3 and get 5.

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

So, 2507 + 2002 = 4509.
