Let's get this math done. We have 2520 and 2058 and we're going to add them all together.

Step 1: We'll start by adding the digits 0 & 8 in column 1 and get 8.

Step 2: We'll start by adding the digits 2 & 5 in column 2 and get 7.

Step 3: We'll start by adding the digits 5 & 0 in column 3 and get 5.

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

So, 2520 + 2058 = 4578.
