How to calculate 77 plus 48 using Long Addition




Here we will show you step-by-step how to calculate 77 plus 48 (77 + 48) using the Long Addition Method. We start by setting up our math problem as follows:

              7 7
      +       4 8
                 

The next step is to add the ones digits together (7 + 8 = 15). Since the sum creates 1 tens digit, we put the 1 in the tens column, and the 5 at the bottom of the ones:

              1  
              7 7
      +       4 8
                5

Then in our final step, we add the tens digits together (including the 1 from the previous step): 7 + 4 + 1 = 12 and put that sum at the bottom:

              1  
              7 7
      +       4 8
            1 2 5

And that is how you solve 77 plus 48 using the Long Addition Method! The answer is displayed mathematically below:

77 + 48 = 125
