We've got two numbers: 54 and 1302. Let's find their sum.

Step 1: We'll start by adding the digits 4 & 2 in column 1 and get 6.

Step 2: We'll start by adding the digits 5 & 0 in column 2 and get 5.

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

Step 4: We'll start by adding the digits 0 & 1 in column 4 and get 1.

So, 54 + 1302 = 1356.
