We've got two numbers: 7440 and 36. Let's find their sum.

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

Step 2: We'll start by adding the digits 4 & 3 in column 2 and get 7.

Step 3: We'll start by adding the digits 4 & 0 in column 3 and get 4.

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

So, 7440 + 36 = 7476.
