Let's get this math done. We have 64 and 5220 and we're going to add them all together.

Step 1: We'll start by adding the digits 4 & 0 in column 1 and get 4.

Step 2: We'll start by adding the digits 6 & 2 in column 2 and get 8.

Step 3: We'll start by adding the digits 0 & 2 in column 3 and get 2.

Step 4: We'll start by adding the digits 0 & 5 in column 4 and get 5.

So, 64 + 5220 = 5284.
