Let's get this math done. We have 5611 and 170 and we're going to add them all together.

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

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

Step 3: We'll start by adding the digits 6 & 1 in column 3 and get 7.

Step 4: We'll start by adding the digits 5 & 0 in column 4 and get 5.

So, 5611 + 170 = 5781.
