OK, let's do this. We've got 5310 and 4032 and we're adding them all together.

Step 1: We'll start by adding the digits 0 & 2 in column 1 and get 2.

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

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 5 & 4 in column 4 and get 9.

So, 5310 + 4032 = 9342.
