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

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