Let's get this math done. We have 1408 and 3076 and we're going to add them all together.

Step 1: We'll start by adding the digits 8 & 6 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 0 & 7 in column 2 and get 8.

Step 3: We'll start by adding the digits 4 & 0 in column 3 and get 4.

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

So, 1408 + 3076 = 4484.
