Let's get this math done. We have 3 and 9722 and we're going to add them all together.

Step 1: We'll start by adding the digits 3 & 2 in column 1 and get 5.

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

Step 3: We'll start by adding the digits 0 & 7 in column 3 and get 7.

Step 4: We'll start by adding the digits 0 & 9 in column 4 and get 9.

So, 3 + 9722 = 9725.
