No problem, let's work through this together. We're starting with 1383 and 8011 and adding them all up.

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

Step 2: We'll start by adding the digits 8 & 1 in column 2 and get 9.

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

Step 4: We'll start by adding the digits 1 & 8 in column 4 and get 9.

So, 1383 + 8011 = 9394.
