Let's get this math done. We have 39 and 700 and we're going to add them all together.

Step 1: We'll start by adding the digits 9 & 0 in column 1 and get 9.

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 & 7 in column 3 and get 7.

So, 39 + 700 = 739.
