Let's get this math done. We have 5113 and 4046 and we're going to add them all together.

Step 1: We'll start by adding the digits 3 & 6 in column 1 and get 9.

Step 2: We'll start by adding the digits 1 & 4 in column 2 and get 5.

Step 3: We'll start by adding the digits 1 & 0 in column 3 and get 1.

Step 4: We'll start by adding the digits 5 & 4 in column 4 and get 9.

So, 5113 + 4046 = 9159.
