We've got two numbers: 1717 and 4262. Let's find their sum.

Step 1: We'll start by adding the digits 7 & 2 in column 1 and get 9.

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

Step 3: We'll start by adding the digits 7 & 2 in column 3 and get 9.

Step 4: We'll start by adding the digits 1 & 4 in column 4 and get 5.

So, 1717 + 4262 = 5979.
