Let's get this math done. We have 1004 and 5361 and we're going to add them all together.

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

Step 2: We'll start by adding the digits 0 & 6 in column 2 and get 6.

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

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

So, 1004 + 5361 = 6365.
