Here we will show you step-by-step how to calculate 12 plus 38 (12 + 38) using the Long Addition Method. We start by setting up our math problem as follows:
1 | 2 | |||||||
+ | 3 | 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 | ||||||||
1 | 2 | |||||||
+ | 3 | 8 | ||||||
0 |
Then in our final step, we add the tens digits together (including the 1 from the previous step): 1 + 3 + 1 = 5 and put that sum at the bottom:
1 | ||||||||
1 | 2 | |||||||
+ | 3 | 8 | ||||||
5 | 0 |
And that is how you solve 12 plus 38 using the Long Addition Method! The answer is displayed mathematically below:
12 + 38 = 50
