How to calculate 12 plus 38 using Long Addition




Here we will show you step-by-step how to calculate 12 plus 38 (12 + 38) using the Long Addition Method. We start by setting up our math problem as follows:

              1 2
      +       3 8
                 

The next step is to add the ones digits together (2 + 8 = 10). Since the sum creates 1 tens digit, we put the 1 in the tens column, and the 0 at the bottom of the ones:

              1  
              1 2
      +       3 8
                0

Then in our final step, we add the tens digits together (including the 1 from the previous step): 1 + 3 + 1 = 5 and put that sum at the bottom:

              1  
              1 2
      +       3 8
              5 0

And that is how you solve 12 plus 38 using the Long Addition Method! The answer is displayed mathematically below:

12 + 38 = 50
