Here we will show you step-by-step how to calculate 19 plus 20 (19 + 20) using the Long Addition Method. We start by setting up our math problem as follows:
| 1 | 9 | |||||||
| + | 2 | 0 | ||||||
The next step is to add the ones digits together (9 + 0 = 9) like this:
| 1 | 9 | |||||||
| + | 2 | 0 | ||||||

| 1 | 9 | |||||||
| + | 2 | 0 | ||||||
| 3 | 9 |
And that is how you solve 19 plus 20 using the Long Addition Method! The answer is displayed mathematically below:
