Here we will show you step-by-step how to calculate 11 plus 70 (11 + 70) using the Long Addition Method. We start by setting up our math problem as follows:
| 1 | 1 | |||||||
| + | 7 | 0 | ||||||
The next step is to add the ones digits together (1 + 0 = 1) like this:
| 1 | 1 | |||||||
| + | 7 | 0 | ||||||

| 1 | 1 | |||||||
| + | 7 | 0 | ||||||
| 8 | 1 |
And that is how you solve 11 plus 70 using the Long Addition Method! The answer is displayed mathematically below:
