Let's get this math done. We have 315 and 443 and we're going to add them all together.

Step 1: We'll start by adding the digits 5 & 3 in column 1 and get 8.

Step 2: We'll start by adding the digits 1 & 4 in column 2 and get 5.

Step 3: We'll start by adding the digits 3 & 4 in column 3 and get 7.

So, 315 + 443 = 758.
