We've got two numbers: 1013 and 4906. Let's find their sum.

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

Step 2: We'll start by adding the digits 1 & 0 in column 2 and get 1.

Step 3: We'll start by adding the digits 0 & 9 in column 3 and get 9.

Step 4: We'll start by adding the digits 1 & 4 in column 4 and get 5.

So, 1013 + 4906 = 5919.
