No problem, let's work through this together. We're starting with 1537 and 4362 and adding them all up.

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 3 & 6 in column 2 and get 9.

Step 3: We'll start by adding the digits 5 & 3 in column 3 and get 8.

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

So, 1537 + 4362 = 5899.
