Here we will show you step-by-step how to calculate 2 plus 18 (2 + 18) using the Long Addition Method. We start by setting up our math problem as follows:
| 0 | 2 | |||||||
| + | 1 | 8 | ||||||
The next step is to add the ones digits together (2 + 8 = 10). Since the sum creates 1 tens digit, we put the 1 in the tens column, and the 0 at the bottom of the ones:
| 1 | ||||||||
| 0 | 2 | |||||||
| + | 1 | 8 | ||||||
| 0 |
Then in our final step, we add the tens digits together (including the 1 from the previous step): 0 + 1 + 1 = 2 and put that sum at the bottom:
| 1 | ||||||||
| 0 | 2 | |||||||
| + | 1 | 8 | ||||||
| 2 | 0 |
And that is how you solve 2 plus 18 using the Long Addition Method! The answer is displayed mathematically below:
2 + 18 = 20
