Sure thing! We've got 120 and 3130 and we're gonna add them together.

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

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

Step 3: We'll start by adding the digits 1 & 1 in column 3 and get 2.

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

So, 120 + 3130 = 3250.
