We've got two numbers: 7442 and 2340. Let's find their sum.

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 & 4 in column 2 and get 8.

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

Step 4: We'll start by adding the digits 7 & 2 in column 4 and get 9.

So, 7442 + 2340 = 9782.
