Here we go! We're going to add 107 and 375 together.

Step 1: We'll start by adding the digits 7 & 5 in column 1 and get 12.
We'll write down the last digit 2 and carry the 1 to the next column.

Step 2: We'll start by adding the digits 0 & 7 in column 2 and get 8.

Step 3: We'll start by adding the digits 1 & 3 in column 3 and get 4.

So, 107 + 375 = 482.
