Okay, we are tasked with adding 5281 and 1151. Let's begin!

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

Step 2: We'll start by adding the digits 8 & 5 in column 2 and get 13.

Step 3: We'll start by adding the digits 2 & 1 in column 3 and get 4.

Step 4: We'll start by adding the digits 5 & 1 in column 4 and get 6.
