Here we will show you step-by-step how to calculate 15 plus 10 (15 + 10) using the Long Addition Method. We start by setting up our math problem as follows:
1 | 5 | |||||||
+ | 1 | 0 | ||||||
The next step is to add the ones digits together (5 + 0 = 5) like this:
1 | 5 | |||||||
+ | 1 | 0 | ||||||

Then in our final step, we add the tens digits together (1 + 1 = 2) like this:
1 | 5 | |||||||
+ | 1 | 0 | ||||||
2 | 5 |
And that is how you solve 15 plus 10 using the Long Addition Method! The answer is displayed mathematically below:
