No problem, let's work through this together. We're starting with 2038 and 5207 and adding them all up.

Step 1: We'll start by adding the digits 8 & 7 in column 1 and get 15.
We'll write down the last digit 5 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 3 & 0 in column 2 and get 4.

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 2 & 5 in column 4 and get 7.

So, 2038 + 5207 = 7245.
