Let's get this math done. We have 320 and 7240 and we're going to add them all together.

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

Step 2: We'll start by adding the digits 2 & 4 in column 2 and get 6.

Step 3: We'll start by adding the digits 3 & 2 in column 3 and get 5.

Step 4: We'll start by adding the digits 0 & 7 in column 4 and get 7.

So, 320 + 7240 = 7560.
