How to calculate 19 plus 15 using Long Addition Here we will show you step-by-step how to calculate 19 plus 15 (19 + 15) using the Long Addition Method. We start by setting up our math problem as follows:

 1 9 + 1 5

The next step is to add the ones digits together (9 + 5 = 14). Since the sum creates 1 tens digit, we put the 1 in the tens column, and the 4 at the bottom of the ones:

 1 1 9 + 1 5 4

Then in our final step, we add the tens digits together (including the 1 from the previous step): 1 + 1 + 1 = 3 and put that sum at the bottom:

 1 1 9 + 1 5 3 4

And that is how you solve 19 plus 15 using the Long Addition Method! The answer is displayed mathematically below:

19 + 15 = 34
