We've got two numbers: 5036 and 623. Let's find their sum.

Step 1: We'll start by adding the digits 6 & 3 in column 1 and get 9.

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

Step 3: We'll start by adding the digits 0 & 6 in column 3 and get 6.

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

So, 5036 + 623 = 5659.
