Here we will show you step-by-step how to calculate 19 plus 66 (19 + 66) using the Long Addition Method. We start by setting up our math problem as follows:
| 1 | 9 | |||||||
| + | 6 | 6 | ||||||
The next step is to add the ones digits together (9 + 6 = 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 | ||||||||
| 1 | 9 | |||||||
| + | 6 | 6 | ||||||
| 5 |
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 | 6 | ||||||
| 8 | 5 |
And that is how you solve 19 plus 66 using the Long Addition Method! The answer is displayed mathematically below:
19 + 66 = 85
