Let's get this math done. We have 4016 and 280 and we're going to add them all together.

Step 1: We'll start by adding the digits 6 & 0 in column 1 and get 6.

Step 2: We'll start by adding the digits 1 & 8 in column 2 and get 9.

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 4 & 0 in column 4 and get 4.

So, 4016 + 280 = 4296.
