Ready to do some math? We're starting with 315 and 359 and adding them up.

Step 1: We'll start by adding the digits 5 & 9 in column 1 and get 14.
We'll write down the last digit 4 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 1 & 5 in column 2 and get 7.

Step 3: We'll start by adding the digits 3 & 3 in column 3 and get 6.

So, 315 + 359 = 674.
