Not to worry, we've got 31 and 3006. Let's get to adding them!

Step 1: We'll start by adding the digits 1 & 6 in column 1 and get 7.

Step 2: We'll start by adding the digits 3 & 0 in column 2 and get 3.

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 0 & 3 in column 4 and get 3.

So, 31 + 3006 = 3037.
