Here we will show you step-by-step how to calculate 19 plus 69 (19 + 69) using the Long Addition Method. We start by setting up our math problem as follows:
| 1 | 9 | |||||||
| + | 6 | 9 | ||||||
The next step is to add the ones digits together (9 + 9 = 18). Since the sum creates 1 tens digit, we put the 1 in the tens column, and the 8 at the bottom of the ones:
| 1 | ||||||||
| 1 | 9 | |||||||
| + | 6 | 9 | ||||||
| 8 |
Then in our final step, we add the tens digits together (including the 1 from the previous step): 1 + 6 + 1 = 8 and put that sum at the bottom:
| 1 | ||||||||
| 1 | 9 | |||||||
| + | 6 | 9 | ||||||
| 8 | 8 |
And that is how you solve 19 plus 69 using the Long Addition Method! The answer is displayed mathematically below:
19 + 69 = 88
