Let's get this math done. We have 1210 and 4164 and we're going to add them all together.

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

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 2 & 1 in column 3 and get 3.

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

So, 1210 + 4164 = 5374.
