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
