Let's solve this addition problem. We have 9103 and 383, and we need to add them together.

Step 1: We'll start by adding the digits 3 & 3 in column 1 and get 6.

Step 2: We'll start by adding the digits 0 & 8 in column 2 and get 8.

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

Step 4: We'll start by adding the digits 9 & 0 in column 4 and get 9.

So, 9103 + 383 = 9486.
