Here we will show you step-by-step how to calculate 35 plus 85 (35 + 85) using the Long Addition Method. We start by setting up our math problem as follows:
3 | 5 | |||||||
+ | 8 | 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 | |||||||
+ | 8 | 5 | ||||||
0 |
Then in our final step, we add the tens digits together (including the 1 from the previous step): 3 + 8 + 1 = 12 and put that sum at the bottom:
1 | ||||||||
3 | 5 | |||||||
+ | 8 | 5 | ||||||
1 | 2 | 0 |
And that is how you solve 35 plus 85 using the Long Addition Method! The answer is displayed mathematically below:
35 + 85 = 120
