Let's solve this addition problem. We have 2350 and 2029, and we need to add them together.

Step 1: We'll start by adding the digits 0 & 9 in column 1 and get 9.

Step 2: We'll start by adding the digits 5 & 2 in column 2 and get 7.

Step 3: We'll start by adding the digits 3 & 0 in column 3 and get 3.

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

So, 2350 + 2029 = 4379.
