Let's solve this addition problem. We have 1142 and 6260, and we need to add them together.

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

Step 2: We'll start by adding the digits 4 & 6 in column 2 and get 10.
We'll write down the last digit 0 and carry the 1 to the next column.

Step 3: We'll start by adding the digits 1 & 2 in column 3 and get 4.

Step 4: We'll start by adding the digits 1 & 6 in column 4 and get 7.

So, 1142 + 6260 = 7402.
