No problem, let's work through this together. We're starting with 1530 and 4387 and adding them all up.

Step 1: We'll start by adding the digits 0 & 7 in column 1 and get 7.

Step 2: We'll start by adding the digits 3 & 8 in column 2 and get 11.
We'll write down the last digit 1 and carry the 1 to the next column.

Step 3: We'll start by adding the digits 5 & 3 in column 3 and get 9.

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

So, 1530 + 4387 = 5917.
