We've got two numbers: 1790 and 102. Let's find their sum.

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

Step 2: We'll start by adding the digits 9 & 0 in column 2 and get 9.

Step 3: We'll start by adding the digits 7 & 1 in column 3 and get 8.

Step 4: We'll start by adding the digits 1 & 0 in column 4 and get 1.

So, 1790 + 102 = 1892.
