Here we will show you step-by-step how to calculate 35 plus 15 (35 + 15) using the Long Addition Method. We start by setting up our math problem as follows:

3 | 5 | |||||||

+ | 1 | 5 | ||||||

The next step is to add the ones digits together (5 + 5 = 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 | ||||||||

3 | 5 | |||||||

+ | 1 | 5 | ||||||

0 |

Then in our final step, we add the tens digits together (including the 1 from the previous step): 3 + 1 + 1 = 5 and put that sum at the bottom:

1 | ||||||||

3 | 5 | |||||||

+ | 1 | 5 | ||||||

5 | 0 |

And that is how you solve 35 plus 15 using the Long Addition Method! The answer is displayed mathematically below:

**35 + 15 = 50**
