Here we will show you step-by-step how to calculate 3 plus 20 (3 + 20) using the Long Addition Method. We start by setting up our math problem as follows:
| 0 | 3 | |||||||
| + | 2 | 0 | ||||||
The next step is to add the ones digits together (3 + 0 = 3) like this:
| 0 | 3 | |||||||
| + | 2 | 0 | ||||||

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