We've got two numbers: 5056 and 4012. Let's find their sum.

Step 1: We'll start by adding the digits 6 & 2 in column 1 and get 8.

Step 2: We'll start by adding the digits 5 & 1 in column 2 and get 6.

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

Step 4: We'll start by adding the digits 5 & 4 in column 4 and get 9.

So, 5056 + 4012 = 9068.
